Acoustic Echo Cancellation Flow-Like Node Flow-Like WASM node that wraps thewh1teagle/aec ( aec-rs ) to remove speaker echo from mono WAV recordings. Node acoustic_echo_cancellation takes FlowPath inputs for: recorded_wav : mono 16-bit PCM WAV containing microphone audio plus echo echo_reference_wav : required mono 16-bit PCM WAV of the clean playback/system-output signal output_wav : FlowPath where the cleaned WAV will be written config : typed timing and preprocessing settings It outputs the written FlowPath plus sample/frame counts. The echo reference is not optional. Capture the audio that was sent to the speakers/headphones, remote call output, or system output as a separate mono WAV while recording the microphone. If you only have the microphone recording, use a denoise/noise-suppression node instead of acoustic echo cancellation.
