JavierCarles Posted February 16, 2020 Report Share Posted February 16, 2020 Hi folks, I've had this beeping/pulse sound issue with my G3 these two last days of shooting in two different locations. Have a listen here --> (5 seconds audio) 9C7JOaTy https://drive.google.com/open?id=1O73QDLKLfPaWPiQYrRCNpnDM (longer version here --> https://drive.google.com/open?id=1ncHqt0VoH5PP0DeUNf1TU-jyR0dvOdXT ) I don't understand what the heck is it, and is driving me crazy; been testing at home with exact setup and all and the sound does not appear. I can 90% assure that is NOT (or shouldn't be) the following (since I've tested it) - can't be cables xlr (one new and the other is just fine) - lapel mic Sanken cos 11d is just good and friend been using it and it's good) - recorder ZoomF4 (it works well and no P48 in channels; tried in all of them) - can't be batteries eneloop AA 5 months old; weren't full while it happened but still two lines and it just doesn't make sense) - doesn't make a difference if pilot tone was active or inactive; the sound was still happening. Same with squelch - I did scan new freqs; even between takes - no phones on actors I'm not a very tech guy but does that sound like electronic issue? .. or cable/plug of the sanken? But been trying them right now at home and no issues whatsoever.. even recording. Or is it more like cell interference? FYI I'm powering my F4 with a TalentCell battery that it should be good. Any help will be much appreciated. Thanks! Quote Link to comment Share on other sites More sharing options...
Eric Toline Posted February 16, 2020 Report Share Posted February 16, 2020 While the noise is very low level it's there. My guess would be something in the air that's being picked up by your wireless. Quote Link to comment Share on other sites More sharing options...
sciproductions Posted February 17, 2020 Report Share Posted February 17, 2020 Just out of curiosity did you change frequency each day? I think that might be a form of interference. Quote Link to comment Share on other sites More sharing options...
Rick Reineke Posted February 17, 2020 Report Share Posted February 17, 2020 I used to encounter that type of 'chirping' noise occasionally, but i was not only with wireless gear. I think it emanated from early smart phones (Black Berrys and such), I recall it entered through poorly shielded and unbalanced cables.

berniebeaudry Posted February 18, 2020 Report Share Posted February 18, 2020 As Eric said, your wireless must be picking up something that is specific to the locations you were in. It could be environmental or electronic or a combination of both. It's very obvious on the longer piece you posted. Looking at it in a spectrogram in RX 6, its a regular pulses that are in most of the vocal range. Not very loud but certainly noticeable. I did a quick test with the declick module in RX and it was able to get the pulses out without much damage to the voices. I did screen shots so you can see what the pulses look like before and after declicking. Here's a close up of the pulses: Quote Link to comment Share on other sites More sharing options...
berniebeaudry Posted February 18, 2020 Report Share Posted February 18, 2020 I used a different color option and zoomed in further for the pulse close up so they're easier to see. Quote Link to comment Share on other sites More sharing options...
Jacob Gustavsson Posted February 18, 2020 Report Share Posted February 18, 2020 Hey Javier, Is the noise still there when you power it without the talentcell? Quote Link to comment Share on other sites More sharing options...
JavierCarles Posted February 20, 2020 Author Report Share Posted February 20, 2020 Hi everyone, thanks very much for the replies! And Bernie specially for your time with the RX, amazing! I'm pretty sure it was happening due to the wireless remote focus pulling thing and/or other wireless things in the Amira they were using, 'cause it was full with stuff I've never seen before. Maybe some bluetooth things -- I should have asked exactly what they were using.. (although it wouldn't have changed much I believe). I'm saying this 'cause it happened on both days of shooting, in different locations (2nd one more present though), and it did not happen at all at home on my own with exact setup, so I want to believe is something to do with that focus thing. I did change frequencies and didn't change anything if I run my F4 with the external battery or the AA batteries. I'm shooting again this weekend, with different crew; let's see what happens ! If it happens again I'll get quite worried. Thanks again! Quote Link to comment Share on other sites More sharing options...

I saw this as a learning challenge as I've not encountered that type of noise before. If production wants to clean that up let me know and we can chat about it off line.

vale Posted February 22, 2020 Report Share Posted February 22, 2020 I had this same issue, a couple of times, and it turned out it was the focus puller system (I guess it was a CineTape that time). Quote Link to comment Share on other sites More sharing options...
JavierCarles Posted February 24, 2020 Author Report Share Posted February 24, 2020 Hey Folks, YES, it was most likely the frikking focus puller thing because I was shooting this weekend with a different crew (with a different focus puller device) and it did not happen. So yes, it's all good ! Thanks again everyone!! Quote Link to comment Share on other sites More sharing options...
