How it works

Your audio never leaves your device

The speed changer uses your browser's Web Audio API to decode the file, resample it at your chosen rate, and re-encode a 16-bit PCM WAV — all on your machine, no server round trip.

Step 1

Drop the file

MP3, WAV, OGG, M4A or FLAC — up to 25 MB.

Step 2

Choose a speed

Slide from 0.5× to 2× or tap a preset, then apply.

Step 3

Download the WAV

Preview first, then save the re-timed audio.
