Hi, i had the same problems when i used the mic input. The final solution for me was to use a smal mixer whit the primo mics, connected to the line input.Listen here ( lot of wind now):https://wijnandbredewold.nl/LIVESTATIONRegards, Wijnand -------- Oorspronkelijk bericht --------Van: Gívan Belá xgz@societyofalgorithm.org Datum: 26-05-2022 09:56 (GMT+01:00) Aan: locustream@locusonus.org Onderwerp: [locustream mailing list] Another question Zero Pi W + IQaudIO + elektrets: annoying clicks/noise 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 cardI 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 microphonesBut when I connect any electret microphone pair to the stereo plug, there is an annoying digital rhythmical click/tik/noiseburst in the soundI 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 soundAnd 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 cardThat 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! ~GPs the stream is currently at: http://locus.creacast.com:9001/mobile_kra.ogg
