using USB DAC/ADC/Audio Interface with a Raspberry Pi 4B - as a BirdNET Pi (it detects and automatically identifies birds by their song/calls)
I am using a Clippy EM272 Microphone via TRS-TTRS converter
micbooster.com
I was first using a 96/48 Audio interface - Ugreen - Ugreen 94khz/24bitwhich seemed OK but gain seemed lower than I would have hoped
I accidentally broke that one so replaced it with a 384/32bit - Ugreen 384khz/32bit - one which I hoped might give out more voltage on the signal to the mic - but if anything (hard to directly compare) the voltage and gain seems a bit lower
Question I have please is that the CM272 has I think a voltage range of 2V-10V - 2V being about the minimum
I literally can't find the output voltage to the mic listed on any of the USB Audio interfaces/DACs/ADCs, just distortion, power to Headphones etc - so for my usage (I'm not even using the DAC, only the ADC) it is very difficult to find what I am looking for. Any recommendation please ? or should I go for something like the cheapest Focusrite I can get (USB powered - hopefully will be able to be powered from the Pi)
many thanks for any help
