## Roadmap
|
||||
|
||||
0. implement JACK backend, get examples working
|
||||
0. Steal PulseAudio's default channel maps per channel count
|
||||
0. Ability to parse PulseAudio's "front-left" "front-right" channel label strings
|
||||
0. When two soundio clients are talking to each other, use port names to
|
||||
negotiate channel maps.
|
||||
0. why does pulseaudio microphone use up all the CPU?
|
||||
0. merge in/out stream structures and functions?
|
||||
0. implement CoreAudio (OSX) backend, get examples working
|
||||
0. implement WASAPI (Windows) backend, get examples working
|
||||
0. implement ASIO (Windows) backend, get examples working
|
||||
0. Avoid calling `panic` in PulseAudio.
|
||||
0. Avoid calling `soundio_panic` in PulseAudio.
|
||||
0. Figure out a way to test prebuf. I suspect prebuf not working for ALSA
|
||||
which is why we have to pre-fill the ring buffer with silence for
|
||||
the microphone example.

|
|||
0. Allow calling functions from outside the callbacks as long as they first
|
||||
call lock and then unlock when done.
|
||||
0. Should pause/resume be callable from outside the callbacks?
|
||||
0. device.name -> device.id, device.description -> device.name
|
||||
0. PulseAudio: when opening a device start it corked that way we can get
|
||||
accurate buffer readings
|
||||
0. clean up API and improve documentation
|
||||
- make sure every function which can return an error documents which errors
|
||||
it can return
