Change WAV sample rate

Upload a WAV file and resample it to the sample rate you need.

New sample rate

Your file never leaves your device. All processing happens right in your browser, and nothing is uploaded to a server.

Resampling WAV without leaving the browser

Pick a new sample rate and the tool resamples your WAV to it, writing a fresh uncompressed file. The classic moves: 44.1 kHz for CD-lineage audio, 48 kHz for anything destined for video, and lower rates like 16 kHz where speech pipelines demand them.

Mismatched sample rates cause real problems: audio drifting out of sync in video editors, DAWs forcing project-wide conversions, and transcription APIs rejecting input outright. Resampling once, correctly, avoids all of it.

Quality notes for the careful

Downsampling discards frequencies above the new Nyquist limit (half the sample rate); content below it is preserved by the resampler. Upsampling never adds detail, it only makes the file bigger, so upsample only when a tool insists on a specific rate.
