Possible to record from audio output? about coast_audio

[SKKbySSK]

It's not easy but yes, this library was made for such a complex audio processing use case.

To do that, I think you need to reimplement the audio file playback logic by using coast_audio's node graph system.
You should use these nodes for building the audio graph.

• GraphNode
  • for building audio node graph.
• MabPlaybackDeviceNode (example)
  • for playing audio.
• DecoderNode
  • for decoding audio data.
  • You can use MabAudioDecoder for decoding wav, mp3 and flac files.
• MixerNode
  • for mixing decoder nodes.

(Note that the Mab~ classes are located at coast_audio_miniaudio package)

Please see the audio_graph_example to learn how to build the graph.
This example also contains writing wav audio file logic.
