As is probably well known the Cirrus Logic Audio Card has stopped being manufactured and as such is proving very difficult to get. My reasons for wanting this card was that I needed something with a sample rate of 192khz for recording audio due to Nyquist's Sampling Theorem meaning I would be able to record at half this so 96khz.
Most of the replacements being talked about for this audio card focus on audio output. Those that do audio input, such as the Fe-Pi and the AudioInjector stereo sound card, usually only have a sample rate of 96 khz. The only sound card so far that suits my purpose is the PiSound however at $99 it is a significant step up in the price compared to the Cirrus Logic Audio Card.
Therefore my question is if anyone knows of an audio card for the Raspberry Pi 3 which has a 192khz sample rate?
