List of Core Audio iOS apps

Apps that support Apple’s Core Audio framework allow you to use iOS compatible audio interfaces, such as the iXY Mic or the Apogee Jam (to name a few), to send audio in and/out of your iDevice to be recorded, processed live, amplified via external speakers. You can also use just about any (depends on the power requirements) USB audio interface and an iPad Camera Connection Kit. Here’s a regularly updated list of iPhone / iPad apps that support connecting external audio hardware:

    Not sure if it’s what you’re looking for — my app Audio MIDI Connect uses CoreAudio, and converts pitch to MIDI notes. It’s worked with every piece of audio input hardware I’m aware of (this is all handled by iOS, so it’s not like we’ve done anything special).
