Windows implementation of audio_flutter - WASAPI loopback and microphone capture plus render playback.

Changelog #

0.1.0 #

  • Initial package: Windows capture and PCM playback for audio_flutter over WASAPI. The native half has not been compiled — see the README.
  • System audio through shared-mode loopback on a render endpoint; microphone through the same client on an eCapture endpoint.
  • Endpoint mix format is read rather than assumed, decoding IEEE float32 and 8/16/24/32-bit integer PCM, down-mixing to mono and resampling with a phase-continuous linear interpolator.
  • Capture threads run on the MMCSS "Pro Audio" task and poll at half the endpoint buffer in 5 ms slices, so stop latency stays bounded.
  • Bounded frame ring per session honouring maxBufferedDuration and every PlatformCaptureOverflowPolicy, drained by readCaptureFrames; audio is pulled, so only lifecycle events cross the event channel.
  • Stall watchdog reporting CaptureStalled when an initialised capture never delivers audio.
  • Endpoint enumeration for both capture inputs and render targets, plus playback through IAudioRenderClient.
  • processIds and rawRecordingPath are rejected rather than silently ignored.
