Another question Zero Pi W + IQaudIO + elektrets: annoying clicks/noise
by Gívan Belá 29 May '22

Hi Dear Locustreamers, Since a while I am trying to get a good quality out of the combination of a Zero Pi W with IQaudIO card I am running it over my wifi net since there is no phone connection anyway in many places around And for testing I run it on the normal electricity grid.. but I will make a battery/solarcharge unit soon… So, I had no problems configuring the thing like indicated on the locusonus website, it is really neat and easy and well documented (Thanks for that! Beautiful!) Also the file “Streambox-Off-grid-with-IQ-Audio-Code-Zero-and-solar-Summer-2021” was helpful… The system itself is running quite stable for a couple of weeks now, but I am having major problems with the electret microphones But when I connect any electret microphone pair to the stereo plug, there is an annoying digital rhythmical click/tik/noiseburst in the sound I tested some self-built pair and also a pair I bought some time ago, the EM272 microphones are fine and are by themselves providing a clear sound And not so much noise.. compared to the built-in MEMS which are rather noisy! But these rhythmical clicks are quite bad and irritating after a while! (I think Golo is on this list too and he is having the same problem, He thinks it has to do with interference from the modem But mine is really far away.. and moving closer or further does not change anything to it… ) Now, I played around a little and noticed that when I change input to the MEMs the digital click is still there until I disconnect the electrets… Actually when I simply plug a minijack without cable in the connector, I hear the clicks again! Finally, I was thinking of streaming binaural, and connected a HR-VR zoom line output to it with a minijack, and … THE CLICKS ARE GONE! So now I am wondering what the solution could be… I am not an engineer or have any of these skills, but first I thought it was the ADC on the card That was doing the bad job, but since it is working perfectly with a line in from the H3VR (btw - the binaural stream adds a nice spatial aspect), Maybe it is the signal itself from the electrets and how it is handled on the IQaudIO - do I need to solder resistors and capacitors between pins or what can I do? Help! ~G Ps the stream is currently at: http://locus.creacast.com:9001/mobile_kra.ogg

REVEIL / SC9 — after
by Grant Smith 11 May '22

11 May '22

Dear List Thank you to everybody who contributed to the ninth edition of Reveil, as a streamer, broadcaster or listener, by setting up a sound camp or creating a live project. Special thanks to Stéphane, Renaud and all at Locus Sonus, with the support of Creacast, for work on the Icecast server so the broadcast ran smoothly for the full 24+1 hours. Towards 2023, we are thinking about the archive of ephemeral sounds accumulated over what will be 10 years of these activities, and how the Acoustic Commons network can be further imagined and supported. It is a privilege for us to be part of these collective works at the start of May each year. As always we welcome your thoughts on what should be kept and what needs to change. This could be a good place to have those discussions and / or, if you find time, please consider answering some of these six questions <https://forms.gle/nuGD8CCnEAMT8x52A>. The stream <https://streams.soundtent.org/manage/streams> and project <https://streams.soundtent.org/manage/projects> pages created for the event are editable. Recordings, images and text can be added, as a long term archive. Selected pages and a full list of streams and projects from Reveil 8 are collected in this sampler <http://acousticommons.net/files/reveil_8_sampler.pdf>. Thank you! Best wishes Soundcamp soundtent.org <http://soundtent.org/> Acoustic Commons network: acousticommons.net <http://http//acousticommons.net/>

live stream tonight
by Jem Finer 06 May '22

Hello, I’ve left my streambox in Highgate Woods, North London. A lovely old piece of ancient woodland with a lot of birdsong, though now it’s quietened down for the night. The odd sound, a breeze in the trees and distant planes and traffic and trains. http://locus.creacast.com:9001/london_wildmic This is a bit of an experiment to see if the stream will run reliably. I had big problems last Friday night / Saturday morning in a different location with the stream going totally offline after a few hours. And when it was online there was em interference and it seemed to dropout every 30 seconds or so. I think the cause was leaving it in an area of poor reception though my phone read two bars of 5G when I left it. And there is a question: I assume that if there is 5G there is also 4G (which my SIM card receives). But maybe that’s a problem ? Tonight I left it in a location of 3 bars of 5G. It seems more stable but went offline about 30 minutes ago - ‘not found’ - and then came back again. At least it seems to be able to log itself back on. And sometimes the stream stops and I have to reload the url. I’d be interested to know what anyone thinks in regards to where the problems lie. Is it a 5/4G discrepancy, local connectivity wavering, or even the server ? Hopefully it will last the night, the sounds of dawn I imagine will be beautiful. Thanks, Jem
