Why this tool is useful
Create an uncompressed, widely readable editing copy from audio that the current browser can decode, while keeping private recordings on the device.

Private Audio to WAV Converter
Decode a browser-supported audio file, optionally change its sample rate or channel layout, and download a PCM WAV without uploading the source.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
Web Audio decodes the input, the browser performs bounded linear resampling and channel mapping, then writes a PCM WAV header and interleaved 16-bit samples.
Practical example
Choose a browser-playable voice recording, convert it to 16 kHz mono WAV, inspect the reported duration and download the local result.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
