RtAudio or PortAudio, which one to use?

Question

I\'m considering RTAudio + RTMidi and PortAudio + PortMidi for a new project that requires realtime audio and midi procesing. Can anyone with experience using both libraries rec

Answer 1

The PortAudio Java bindings are oversimplified. For example, you cannot set exclusive mode or shared mode for device access, which is a shame because it effectively steals 7ms of less latency from you -- especially if you capture microphone input (where usually no shared access is necessary) under Windows 10. If you count in output, you lose out on 14 ms RTT for monitoring your mic/stuff.

RtAudio seems to have WASAPI support now, but I'm not sure if it's better than PortAudio's. But are there Java bindings? Wasn't asked in the question, I know, but still ... :)

Another, rather new project is XtAudio. It exposes exclusive and shared access to devices as different sets of devices to the frontend and in general seems to have a better API support. Don't think it supports MIDI tho.
