(...) Not only the earpads were crumbling (literally), but the sound had changed in a way I couldn't explain: bass and midbass completely gone, treble harsh and overwhelming (...)

Not sure if it was because I was the last of the thread previously or because I’ve just had a few socially distant beers bought for me ... but,

I’ve actually recently picked up my FOURTH set of 7506s despite what I’ve said and think about them, this time second hand because they were a cheap extra set of level limited phones which I can always use. All my sets now have crumbling pads (with new covers over them) but the “treble harsh and overwhelming “ was always there from new!

For me, so far, apart from the earpads (in all cases less old than my DT phones where the ear pads are fine) I am pleased to say that they have not changed one bit!

Hi Merijn,

welcome to JWS. I’ve had my stereo pair of MKH 8040 cardioids since pretty much they were introduced, 2007 or 2008. I use them with softies, homemade softies, light waves and BBGs but always cover the back end with a short cut strip of tubular foam to catch the microphony wind noise when doing so. Find some cheap (pound shop) bicycle handlebar foam strips and cut them to just cover the remaining body length and a tad more over the XLR ... it’s the body of the MXS which is sensitive so you don’t have to cover the entire XLR. I prefer using a slightly softer handlebar foam than the more rigid but I doubt it actually makes any difference, it’s just covering the MXS xlr mic shell that’s important.

Depending on how you’re using clips /suspensions it’s fairly easy to cut slits through handlebar foam to accommodate them without compromising where wind might hit: if using the mic clips which come with 8020 etc series just cut a slit 3cm at the bottom where the clip goes and all is covered fine. If using suspensions or whatever have a play about but I’ve never not been able to sort it out. If using supersofties I would be personally tempted to pull a nylon short stocking over the whole apparatus just as a final thing but again, that’s just me- I wouldn’t say it’s necessary.

Really, in more than ten years this has solved the microphony noise problem whenever wind has been light enough to not need a full contained zeppelin- and possibly like you when wind is not an issue at all I am happy to use my Bruel and Kjaer omnis outside with absolutely no wind protection at all ... but this doesn’t happen all that often! In comparison, I would think that my 8040 body shells are more sensitive to wind/touch etc than my MKH40 but not even as much as my Schoeps which I couldn’t imagine using without suspension or cover.

Hope this helps (and sets your mind at rest when you get a chance to find an open shop), best,

Jez

Hmm, don’t have one (and prob never will) but is it not a question of the air around it optimising the successfulness? So a BBG or similar would be a good outdoor choice (long enough - I think so?) otherwise, going thinner, a ‘lightwave’ tube with windjammer? Yep I know this is not much help (ie there probably isn’t a ready made suspension with windshield option available) but I reckon it’s diy... possibly just a softie with a little extra foam for suspension and the softie attached somehow to the boom? Like I might do with 4060s (albeit not booming..!) ???

Hi Nicky,

I filmed an octogenarian choir on the Polish Ukrainian border several years ago - a great time and a great bunch of folk and I hope they’re all getting close to or surpassing the 100 years ...

Too many useful replies already to try to quote examples, but I would say this is one situation where I would try to get an MS rig in there :

I am saying this as a post person and potential dubbing mixer ...

1: boom (swing boom) in mono - the S is both useless and a distraction in a non-fixed position for post and ambience can or will be added or faked even for the “deliverable necessities” so don’t worry about that - ‘content’ requires mono - “the message”!

2: if you decide to try MS (and having an MKH30 I think you should) use it only for fixed mic positions for subjects when there is a likelihood they may burst out in song (=all the time as far as your director is concerned!!)

So, with that in mind: try to work out - can you swing a boom and have a stand ready with an MS rig? Does the MKH50 always have to be paired with the 30 on a suspension? I kind of go with Fred saying have a separate stereo ambience rig on a stand and two boom options for inside/outside. I also think that a wider mic than the 50 (even the 40 is a narrow cardioid) could be a nicer choice. But will you have this opportunity or speed to set up on the job? I don’t know- you might have a leisurely shoot or a frantic shoot.

I would consider either having a totally separate MS rig (with stand) for all the music stuff (even the ambience, but for me this is secondary and less important from a content point of view) and a boom with indoors/outdoors choices, or have the mkh50 always ready with the 30.

Just know that when “booming” MS to act like a tripod not like a boom. And let post know when, why and how you recorded the MS tracks (so if there are sudden shifts then post is aware).

Big (stereo) rycotes are I believe considerably harder to boom than normal ones: I’m not sure what you have yourself. I would consider quicklocks between say 50 and 416, and maybe some easy way to mount a 30 to the 50 if you go that way - compromising the 30 but ensuring the 50 is good for sound. But it depends on what you and the director expect to record in what condition (specifically interior or exterior). There’s the possibility of keeping the 50 in a suspension with a clip to add the 30 when desired? Be aware the 30 will be microphonically (handling noise) more sensitive if it’s on an extra cable - which is why I like the older stereo connbox with plug in cables when working with either/or mono and stereo.

One bonus for MS worth thinking about beyond filming is the (once in a lifetime) voices recorded have an extra ambience for eg a record release beyond the documentary.

Enjoy the job. Best skies I have seen besides the Himalayas...

CineW,

I couldn't agree more about current day final stage studio mixers stretching the bleeding edge of audio dynamics. The last 5 to 7 years i have had to have the remote in hand in order to gain up  whispering dialog only to then hear nuclear bomb SPL sound from a roaring jet that blows my hair straight back as I mash the volume button down. I think these mixers get an evil pleasure from what they are doing. My next AV amp is going to have and AGC control.

 

I have ranted about this before on this forum. I'll crawl back into my whole.

Great and depressing thread!  Musta been great back then.  Fisher booms...  Projecting actors...  Quiet sets...  No wires...  Single camera shoots...

 

Those were the days; how I wish I could remember them rather than fantasize about em.

 

But as we are seeing human history isn’t an upward arc, but rather a sine that we’re in a downward leg of.  The negative polarity of our alternating culture.  Maybe these things will come back if people’s sense’s ever return.  HAH!  That’s a laugh!

I agree this is a really great thread with some good information (not to mention pics too)!

To some extent I don't think it is the broadcast rerecording mixer who is to blame for the excessive dynamic range (although sometimes it most definitely is). It is usually the 'direct employer' of said mixer (who indeed may employ said mixer because they have a mutual understanding what dynamic range ought to be on a TV show)!?

Have loudness standards really improved the intelligibility of dialogue ... ?

Next, Izen Ears, "Those were the days"  ... they're still with us in part: for every unconcerned team there's a concerned team; for every lousy location there's an ideal location; for every star who alternates SHOUTS and (whispers) there is an old stalwart who provides the same performance take after take...

Hell, if it wasn't fun why the hell do it?

Interesting thread from the same question we periodically ask ourselves! The stage pictures and RCA ribbons are a delight for me, thank you!

Hi Dan,

to answer your question to me first, as dialogue editor I would be looking for mono fill for the dialogue track(s) - being the 'fill' track which may have been recorded by the PSM specifically to help me with the edit. Of course there is nothing to stop me just using one leg  of a stereo track if room tone has been recorded in stereo.

If I'm handling the ATMOS tracks (which I might well do as a dialogue or effects editor on a job with a few editors) as well as the fill I would most usually put a couple of tracks of stereo room tone, although if I had a good track which fit the scene of a 4.0 or 5.0 I might use that (those). Although this really does depend on the film how we decide to prepare the tracks. Note that I am talking here about "bland" room tone, NOT a detailed ambient recording. Two stereo tracks is often sufficient to be blended and panned multichannel and fill out the mix (remember that the dialogue tracks and more characterful Atmos tracks are also present). In fact an added difficulty of recording a 'plain air' track in 4 or 5 channels rather than 2 is that attention-grabbing little sounds or areas become far more noticeable. Of course this 'difficulty' becomes an asset when recording an ambience (like a country or city scape) where you want to breath life into the sound and to some extent draw the audience attention toward it. I have recorded room tones (as opposed to atmos) in multichannel but it is only when conditions are very good (location acoustic) that you will get tracks suitable for this purpose. Again, if the conditions, and thus sound, was more characteristic, bingo, you are recording not a room tone but an interior and there is nothing to stop an editor using two legs of a blandish multichannel interior to reduce the stereo perception. You probably weren't asking me for a differentiation between room tone and atmos but you did use the term so got my answer thus.

Back to the issue of ambisonics. I avoid it in film generally (search elsewhere why). For recording multichannel ambiences I actually favour a 4.0 approach but often go 5.0 (or am asked to) amusingly for its 'resale' value perception (people [think they] know what 5.1 is and it is surely superior to four point ... whatever it is you just did)! I often go for spaced omnis for all types of film effects but would push people to consider IRT recording.

So a brief look back to your original post (which I'm afraid I can't be much help with either).

On 22 July 2020 at 8:05 PM, Dan Wake said:

I’m looking for those goals:

1) taking field recording audio for 5.1 mix (the mics needs to be enough silent for room tones). Needs it for documentaries and short movies

2) build sound libraries to sell online

3) make field recordings for VR audio (for videogames development). 
 

For 1 and 2, I would say the first mics to buy for film making are a hyper and a shotgun. Perhaps you already have these, perhaps you have no intention to record dialogue but ONLY find jobs where you record effects and atmospheres. I'm not sure what your position is so couldn't think to give advice. For recording effects and field recording in general I would suggest a pair of cardioids or a pair of omnis, or both pairs. For multichannel that's 4 of either or of both.

For 3, I have no experience so wouldn't have commented, but I notice that many are using ambisonics so that's very probably the route to go down. Again (2 again) if you want to sell ambisonic recordings then get an ambisonic mic: I am not in the marketplace for such recordings however.

Personally I had several other mics before I bought my Soundfield or put together my first MS rigs. I use neither generally for film fx recording generally though but they both have other uses. My principal mics for fx are cardioids and omnis although others get a lot of use. My inkling, especially if '3' is really a plan, is to buy, hire or indeed build(?) an ambisonic mic and start experimenting with it.

I must say I hadn't realised but am much impressed by your proposed intention to build an ambisonic mic, and a second order one at that! Me, I'm scared to solder a hirose ....

Best, Jez

Addendum for Werner - are you talking about post for broadcast or for feature film? It is the latter I do not like ambisonics (nor indeed MS) for. I also worked (over the decades) in TV, radio, music where I consider such phase related techniques an asset rather than an issue to manage.

Hi Dan, I wasn't planning on commenting on your original post simply because I have no experience (nor knowledge of for many) the mics you mention, nor really the understanding of what you really plan to do with ambisonic mic technique - but

5 hours ago, Dan Wake said:

Hi, do find the NT-SF1 to be good enough for room tones recordings? Thx

As a dialogue editor, if confronted with room tone recorded on an ambisonic mic, I would:

1. swear

2. listen to decide if it was any good ...

3. if, as expected, it was no good, swear again, then laugh, then find something in my library

4. if it actually seemed useful, say "oh ok" (possibly swear again whilst laughing) and either choose (if possible) or randomly select a single channel of the 4 (to NINE?!?) available and delete the rest.

Although I would expect '3' to be the final stage and if pressed for time just '1'.

Different recording techniques for different purposes. Different media even. Buy the mic that suits what you REALLY want to do ...

1 x hyper, or

2 x cardioid, or

1 x ambisonic

... none of these options (for instance) can be a desirable replacement for any of the others.

@The Immoral Mr Teas , if I may ask, could you elaborate on what you said about MS not sitting nicely with multichannel encoding? I'd be very interested in hearing your thoughts about this.

Personally, I've always found the stereo image of M/S recordings (especially of ambiences) a bit "weird" or "unnatural", for reasons I can't really grasp. I often have this feeling that there's a clear center image, combined with a L-R stereo field that sounds as if it's "behind" my ears, rather than in front, and that (even when reducing the S part of the M/S) the stereo part of the sound is somewhat disconnected from the center part - an issue I never experience with ORTF or XY. When listening on headphones this effect becomes even more pronounced. Does anyone else experience this?

The attractive part of M/S is that it's so much more compact than an ortf setup, and you have a real center, as opposed ot a phantom center.... you win some, you lose some...

I think MS is an excellent technique for many, generally 2 channel, systems or purposes: the two obvious being radio (taking advantage of the inherent mono compatibility) and vinyl (it was rare for me to encounter a tracking or mixing session where MS didn't come up somewhere). I would add any (2 channel) scenario where the sound in front is 'documentary' essential and the sound around it is 'a beautification' which could be the case for radio documentary, podcast ditto and Alan Lomax/David Lewiston/Harry Smith style folk song collection.

It does of course also work in multichannel formats (re ambisonics) but I have personally found that the side signal just becomes a complication in the 5.1 etc formats of film - both in itself within the LCR soundscape and in the encoding to eg Dolby Digital. I'm afraid I cannot comment regarding Dolby Atmos or other more recent systems, perhaps things have moved on. But in my experience 'phase tricks' never worked easily in a film theatre. (Indeed in some ways they don't with vinyl either but there has been many decades of knowing what does work in this field).

I would be interested to hear if there are indeed problems associated with ambisonics in 3D VR production since this is where (after sports broadcasting) the more recent boom in the technique seems to have come from. I have a Soundfield and as mentioned several MS / MSM combo possibilities- I just don't use them for film effects. In fact for film I like the opportunity to go to the opposite extreme from coincident to spaced techniques - although I probably go for the middle ground of semi spaced (such as ORTF) most of the time.

ideally, one should use a cardioid as Mid.This would theoretically result in a perfect XY after matrix.

Absolutely - a perfectly perceived XY sound angle at least.

I wish that Sennheiser would make a 5pin MZX 8030 series module that would allow you to screw on different Mid capsules rather than using the MKH30 strapped to a MKH8040, 8050, or 8060. (Sennheiser, if your on here and take my idea, I want a t-shirt) 

I can only wonder why they never came out with the expected if not promised MKH8030 ... was it expected relative low sales (yet they gave us the 8090) or would they have needed to make it slightly fatter or longer (who would really care)? A mystery. Personally I would prefer to keep the side capsule vertically coincident hence piggy backed but it's not a bad idea at all - particularly for double MS in a blimp.

[edit addendum] - actually when I think about it I would probably prefer such a module over a standard mono MKH8030 purely for the added usefulness even if you didn't intend to screw another 80 capsule in front. There would also be the possibility of screwing a second 8030 capsule in front at 90 degrees (admittedly some fine manufacturing needed here) for a sweet blumlein mic (like a midget SM69 or that nice old Schoeps model) or as part of a WXY array.

Well you could always try to deaden the room when shooting video, although perhaps the clients being seen to wouldn't like the visual change in ambience. Carpet on the floor out of shot, certainly below the mic stands, and some thick curtains or padding on the (out of shot) walls, particularly behind the mics if they're not intended to be seen. The entire Sennheiser MKH 8020-90 range is pretty much the most sensitive and quietest mic you can get beyond extreme specialisation so it's a case of working out a way of improving the acoustics of the room. Once that is addressed I would even consider the 8020 omni mic (up as close as possible out of frame) or the less common wide cardioid (8090 I think). The point Sennheiser are making with cardioids is to have a decent 'null' at the back of the mic (to point to a problem area often) as opposed to more directional mics (8050, 60, 70) where the back of the mic or tube characteristic of the mic picks up more unwanted reflection from the room. As I said before, if you want 'nice', rather than merely documentary, sound the thing to do is to look seriously into changing the acoustic properties of the room itself for the video shoots.

Having sound edited similar scenes you might indeed consider, if duration is not long (ie promo videos) getting an editor to do 'foley' sound editing, similar to the 'super up close' sound of natural history documentaries, although I would only recommend this if you went with suitably skilled people and / or quality studios ... Although getting the acoustic deadened and recording the real thing close is the best first step anyway.

Where in Poland are you anyway? Warsaw and Lodz are both central for tv/radio/film and there are theatre based studios elsewhere. I would highly recommend finding a local sound engineer to guide you.

Best, Jez

(I worked in Poland at TVP and elsewhere so I know what my name means to you)!

Are you talking about a small single channel mic pre? Sound Devices have made two such models in the past and Fostex I think made one more recently. There's probably an older one by Shure too? If nobody chimes in have a search for these three.

Best, Jez

If you're thinking of something you see regularly when a boom op is working with a production mixer and the second person is feeding the camera (or recording double system) however it could be several other things you're thinking about. Zaxcom is another brand to search for the gadget you're searching for. Obvious thing is to reach out to one of the folks you've worked with you remember wearing such a thing ...

and (further edit) I've just realised what the 'C's are down at the bottom ... so more musical than scientific the original compiler ...?

Fred, thank you, that was a great write up. I was also briefly stagier in 1994 to Laurent Quaglio who did films with Ruh (and didn't mess his sound up in post)! I am particularly fond (for Ruh) of Saint Jack (Bogdanovich - Corman - Hefner!!) which is one of the most incredible rostra of actors/ production / tech I can think of and doesn't disappoint. Sadly I never met Ruh but it was a name even in international (meaning non-French here) films when you generally knew you would be in for a good soundtrack.

Well... for me, the only work I've had recently is because of Zoom and Microsoft Teams!

 

One of my corporate clients wants to continue to communicate with their employees, so they use Microsoft teams.  But they're doing it a little differently.  They have each presenter call into their own individual "Teams" meeting.  The only other person on these individual meetings is "us", in the control room.  This allows us (from their control room) to crop and grab almost a full screen iso shot of each presenter that they can switch to at any time and not be at the mercy of "Teams" auto switching.  Then we sent it back out to their employees on yet another separate "Teams" meeting. 

 

The dilemma is the audio, for which they've been hiring me.  Because they have set up all the presenters into different "meetings", and because the employees log into still another meeting to watch and listen, I have to get audio out of all the various meetings (multiple computers) and feed them to the others via multiple mix minuses.  

 

Not all of these "meetings" are sent out live.  Some are edited and sent out later, which allows them to switch to other presenters for reactions shots, something that's not so easily done with multiple people logged into single meeting. 

 

Of course none of this is "location sound", but I'm sure grateful to have the work!

My favourite 'improperly used mic' film is 'Blow Out'. Most of the examples given so far have mics pointed in the wrong direction but mostly in suspensions and wind protection. In Blow Out, Travolta points the mic in the right direction but his fingers do all the suspension in windless exteriors. Certainly get 'A' full bodied wind effect for his producer - if not 1 we'd be proud of. But there's the Lav mic scene - and who us hasn't felt like improperly using a lav in such a way at some point ,'

We're already there!

We've been there for years ... Adjust the skills so we are still needed, and then ... BINGO! folks need quality again, for whatever reason.

Just noticed my 700th post (whey hey!) coincides with Philip's 10,001!  (This was the edit). J

Brightnight, after the last post and very useful detail (= camera records PCM 48k 16bit) I would strongly suggest looking not for a recorder but a "low power PREAMP with XLR in and 3.5 mini jack consumer level output" ... with your extra skills I would consider if it could be externally battery powered and turned on and off with the same switching circuit that turns the camera to record. Perhaps even the same battery unit could power camera and preamp (+ mic)?

Unless you have a spectacular scientific need for going over 48k and 16 bit (better than a CD ... if you remember them) I see no great benefit of going double system (which is what we call separate but synched sound and picture). With your two issues of massive power duration and potential (auto) edit/resync of hundreds of clips I would at least firstly focus on a camera based solution for recording which would just mean 'how to power a decent mic into a decent preamp and send to camera'.

Recorders generally (as I gather) are far more power hungry than preamps / mixers - even though this has deliberately been addressed on the recorder front in recent years. If you look at 'yesteryear's' preamps/mixers from SQN, Sound Devices etc they are already designed for say a day of activity on a set of alkaline batteries, far better in consumption than any recorder. They are also generally more 'bullet proof' than any recorder, especially one on the consumer or semi pro level.

I would look carefully at a few options (please anyone else chime in if they think of similar) such as SQN (possibly even the obsolete SQN 3 if only mono) and from Sound Devices the 302 or the (original) MixPre or (again if mono) one of the early mono preamps. All for the simple reason all these units are extremely reliable in poor conditions. It would then come down to working out if a triggered power feed worked (probably say half a minute for a P48 mic I would guess). I am assuming that all your quality mic candidates are P48 powered. Then just have a feed to the camera (calibrated as best you can, shouldn't be a problem).

If you were insistent about the recorder route I would look at both the Zoom F6 and the Series 2 Sound Devices Mix Pre recorders for their 32 bit function: unmonitored recording is surely the best reason for this feature. Personally again I would STILL be looking at a solid  mic/preamp front end to camera and potentially a second feed to a separate recorder.

My ideas so far. Again, interested to see where this goes and whether either wildlife folk or manufacturers here see this and chime in. I am also very interested in a more detailed description of your existing powering and triggering system for camera as it stands (especially if self built). You probably know that most audio options run around 12volt dc, often 6-18, sometimes wider, although many do not have such great leeway.

Thanks haifai and Jez - some good, pragmatic thinking here; feel a bit dumb that it didn't occur to me that strapping an alternative fig 8 to an existing MS shotgun is an option

NOT what I meant! I meant that the side mic of say an RSM or Sanken could be used yet one could change the Mid mic to another type, say omni or whatever!

It's not definite yet, but most likely each room (3) will use 3 projection screens to display visuals and a pair of loudspeakers for stereo reproduction. I'm pushing for multi-channel sound, but it looks like this isn't a priority for the folks creating the budget...  However, a gig for later in the year (if distance restrictions ever lift sufficiently for filming of crowds) will feature Saxon battle scenes; the director wants immersive sound so I foresee renting a Soundfield - or possibly a double MS rig - come the time. Fingers crossed.

I find ambisonics an excellent potential solution for gallery work (so long as the sound can handle the format, ie phase and abandonment of local definition). When the visuals are the key thing and sound is the poor cousin sometimes it's actually nice to take advantage and allow the sound to show off when it isn't constrained by factors like precise audience localisation (and often sync)...

Ambisonics is MS, too, in the manner that there are two mids (omni and fig8) and two sides (both fig8) ... or is that three? and one mid? or three mids? ughhh! But my point is that MS can be a good recording companion for an Ambisonic replay ... but it will not be automatically straightforward without a mix.

(... cutting here good advice sorry! ...)

I find MS sounding quite "artificial", it becomes even more weird if there are unwanted sounds from behind (e.g. traffic).

Excellent point from a regular MS recordist, that the side mic can pick up unwanted stuff (actually Mungo, it won't be from behind, ha ha, sorry for being the pedant)! Though I should point out that this is not the reason I avoid (the S from) MS for film effects - it is just because the inherent phase replay of MS doesn't sit nicely with multiple tracks in either LCR + surround nor with the encoding of multichannel film systems. I HAVE recorded Blumlein (crossed Figure8) and there are occasions where phase techniques can be used to good effect but it is a complicated situation in film that the rerecording mixer needs to know what is there and judge how it will work with both the coexisting sounds and the replay format. Too often it is just more shit to deal with, and often mute out.

Jez

Brightnight, firstly welcome to JWS - it is an intriguing question. I don't believe such a thing exists, it will certainly have to be created or modified from whatever. My first thought is to find a camera that works both with trigger recording and has a sound input, then either (easiest) connect a microphone which is powered by the camera (and its battery system) or have a low consumption battery (probably electret) or battery - preamp unit (as Rick suggests, running constantly with an external battery) connected which doesn't need to be triggered.

Hopefully somebody here who currently does wildlife (I did many years ago) may chime in on current systems and ideas but I wouldn't be too surprised if it's a choice between,

i. keep close and change the battery / check the results; and

ii. silent

Very interested here on everyone's ideas

Jez

Hi Al, and welcome to JWS 

You may well end up here with a dozen or so testimonies from people saying they get great results with their Schoeps pair, their MKH pair, their Sanken, their RSM, shotgun front end, omni front end, etc etc etc. It's a wide and variable question to advise on and most opinions are going to be valid in their way - so good luck in advance! Hey, here I am!

Personally my MS / MSM rig is variable based around a Schoeps Fig 8 constant (purely because that's what I have) and I concur with haifai that you should leave yourself the choice for variation. Even if you did pick up an 'in one' MS mic like the RSM there is nothing to stop you strapping a different front capsule atop the fig 8 position whenever you wanted to.

For ambience type recordings a subcardioid capsule is often popular, as it can be for musical applications. Halfway between the benefits of omni and cardioid. For fx recording of a 'specific subject' rather than soundscape anything from cardioid to short shotgun. As a sound effects editor I rarely use the side aspect of a MS recording for film tracklay however and even more rarely would record fx in MS: I would just dematrix it if necessary and use the mono front end. Broadcast, radio, podcast, music etc as well as ambisonics is a different thing though.

I have to think though that as a starting off point for a general MS rig you cannot go wrong with 'cardioid front, fig 8 side' but the best advice is already in the reply above mine - try a few out and decide what suits your needs best
