type AudioStreamDecoder ¶

type AudioStreamDecoder interface {
	Push(data []byte)
	EndInput()
	Next() (*model.AudioFrame, error)
	Close() error
}

AudioStreamDecoder is a generic interface for decoding compressed audio formats (like MP3, WAV, FLAC) into raw PCM AudioFrames suitable for LiveKit WebRTC output.
