What Split Audio does

Cut a long audio file into equal pieces — by duration or piece count — and download as ZIP. The result is a ZIP, WAV, MP3 file you download directly.

How it works

Web Audio API + AudioWorklet for low-latency DSP, ffmpeg.wasm for codec encoding, and a custom WASM SIMD path for time-stretching and pitch-shifting. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
