Audio In

Anyone have good suggestions for capturing audio in ?

Thanks in advance.

What sort of audio source? From a microphone?

Yes a mic, I would like to record and have playback.

A USB microphone is probably the best (only?) option. You can record the audio with Alsa as described in this Stack Overflow answer below.

Thanks for reply. I am trying to find something other than usb. Trying to keep a small foot print if possible .

A small USB microphone is probably as small a footprint as you could get. The alternative is an analogue microphone and an additional ADC to convert the analog signal from the microphone to a digital one that can be understood by the Pi, but you’ll struggle to sample quickly enough to get decent quality.

It’s up to you, really. I always tend to go with the solution with the least friction which, in this case, is probably a small USB microphone.

Radio mic?

Thanks for the reply. I have usb working, most mic set ups seems to large form factor for what I am doing. I am learning ADC using 12, 16, bit chips with mems and electorate mics. Be great if the Phat dac had ins on it.

Thanks again.
