Convert browser-decodable audio into 16-bit, 24-bit or 32-bit float WAV, with sample-rate and channel choices.
No file selected.
Up to 128 MiB per file; decoded audio up to 256 MiB (about 23 min mono / 11½ min stereo). Formats depend on your browser's decoder. Working audio uses 48 kHz; exported WAV uses your selected rate.

Load audio to choose a section.
Click the waveform to seek, or use the adjacent transport and exact time controls. Live audition previews channel routing only; sample-rate and encoding changes require the generated WAV. This is the original source waveform. No tail is appended. Review the processing notes and generate the actual WAV before downloading.
Playback stopped.
Rate and encoding changes are heard in the generated WAV. Uncheck to compare original decoded audio. Exports always use selected settings.
The original file stays unchanged.
Input is decoded by the browser at the shared 48 kHz working rate; original sample rate/codec quality is not preserved. Lower-rate exports use a normalized 96-tap Blackman-windowed sinc with a conservative transition band and clamped edges. Format conversion cannot recover lost information. Live audition previews channel routing only; generate and play the actual WAV to hear rate/encoding changes. WAV only: no MP3/AAC encoding, compressed-size guarantee, tags, artwork or dithering.

WAV | selected channel count and sample rate. Review the output plan before exporting. Input up to 128 MiB; source/output float buffers each up to 256 MiB, subject to device memory. Final PCM clipping is counted. Tags/artwork are omitted. Settings changes clear exports; Stop terminates the local worker. No source or settings are sent to a server.
Your audio is never uploaded to any server. Decoding, effect processing, playback and WAV encoding run locally with self-hosted code. Source files stay unchanged, with no account or audio history.

Channel routing applies live. Rate and encoding changes are heard in the generated actual WAV. Settings are delivered to the playing local AudioWorklet without restarting the source. Continuous controls use short smoothing transitions; discrete routing or direction changes may click. Exports apply current fixed settings, not a recording of knob movements. Original comparison affects monitoring only.
Duration follows the original apart from output sample rounding, with at least one output frame and no appended tail. Channel and sample-rate choices are explicit in the output plan. The converter supports 16-bit PCM, 24-bit PCM and 32-bit float WAV; other tools export 48 kHz 16-bit PCM WAV. Tags/artwork are omitted. The actual encoded player and waveform must load before download enables.
Seeking uses the original timeline. Current fixed routing settings apply at the selected cursor; smoothing during live edits is not recorded in exports.
One mono/stereo file up to 128 MiB, decoded at 48 kHz within a 256 MiB float budget. Output has its own 256 MiB float budget; device memory may impose lower limits. Browser decoder support varies. Live AudioWorklet needs HTTPS or localhost and a supported browser. Stop/edit/clear/replacement terminates export and discards obsolete results.
