Hi,
I’m close to get a raspberry pi 4, and to try out Sonic Pi, but I wonder which audio interface would be recommended ? My use would be to use Sonic Pi as on the fly effect for vocals, so I would need at least 1 input, and of course 1 output, at least 44.1 kHz 16 bit. What I found up to now :
-
Hifiberry : very compact but seems to be dedicated to audio streaming (small RCA connectors without any input)
-
Pi sound : very expensive and way too high performances for my application
I would like to find some small and reliable solution… 
Any advice ?
Thanks
