Stereo split and noise gate
Split stereo into mono WAV, swap or mute outputs, and optionally suppress low-level gaps with a separate gate on each output.
About this stereo split and noise gate
Split stereo into mono WAV, swap or mute outputs, and optionally suppress low-level gaps with a separate gate on each output Processes streaming audio and video buffers directly in the browser using HTML5 Media and Web Audio APIs with zero server uploads.
Audio and video decoding pipeline
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Choose audio, optionally swap source channels or mute either output, then process and download left-channel.wav and right-channel.wav. Both are mono PCM16 WAV at 48 kHz. Both gates start off. Enable either output gate and choose a threshold from −80 to −10 dBFS (initially −40). After optional channel swapping, each enabled gate opens when a 10 ms block peak reaches the threshold, with a 2 ms gain ramp. Full output mute takes priority.
Worked media transformation example
Scenario: Stereo split and noise gate
Sample input:
Processing: Swap routes source right to left output and source left to right output. Gate and mute apply to the named output after routing. Mute silences the entire output; the optional gate suppresses only low-level blocks. Both gates start off.
Illustrative output:
Buffer duration & codec support limits
Operational constraints and validation boundaries: Files must be smaller than 100 MB (100,000,000 bytes), with at most 128,000,000 bytes of decoded Float32 samples across all channels. Native channel splitting uses only the first two channels; mono input is rejected. Both outputs retain frame count and sample order. Muting removes all signal, including speech. The original splitter below retains its unchanged routing. This level gate can suppress quiet wanted sound. Noise overlapping louder content remains; it is not spectral denoising or source separation. Gate settings persist when choosing another file. Changing any setting clears the previous outputs.
Audio and video rendering in Stereo split and noise gate depends on browser hardware and supported media codecs. Verify playback compatibility on your target platforms.
In-memory audio-video processing boundary
File buffers and document assets in Stereo split and noise gate are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
