Audio Channel Extractor
Extract one decoded channel from a multichannel audio file and export it as a mono WAV.
What this tool does
This tool copies one decoded channel into a mono WAV. It does not mix, rebalance, reconstruct or infer speaker/channel labels.
How it works
The selected file is decoded with the browser Web Audio API. The analysis or channel operation runs locally on decoded PCM samples. Outputs are generated without altering the original file.
Limitations and interpretation
Browser codec support varies. Results describe decoded sample data only and must not be presented as forensic, certified metering, perceptual-quality or mastering evidence beyond the stated calculation.
Privacy
Processing for this tool stays in the browser and the selected file is not intentionally uploaded by this page.
FAQ
Does it modify the source? No. Can unsupported formats be forced? No; decoding capability depends on the browser. Is the result a quality score? No.
