Sample & Stem Studio

Split any song into stems.
Sample, remix, reassemble.

Salvo captures or loads audio, lets you edit it — trim, speed, pitch, effects — and separates it into vocals, drums, bass, and other. Runs privately on your own machine.

Free. Private. No account required.

Built for people who take sound apart

AI stem separation

Isolate vocals, drums, bass, and other from any track — fast, on-device, no upload.

Real editing

Trim, time-stretch, pitch-shift, and add effects. Shape the sample before you flip it.

Private by default

The local engine is offline, unlimited, and accountless. Your audio never leaves your Mac.

Right in the browser

A lightweight extension with a popup and a side panel — capture what's playing and go.

How it works

  1. 1 Install the extension and the free macOS companion.
  2. 2 Capture what's playing, or load an audio file.
  3. 3 Split into stems and edit — then export your sample.

Your audio stays yours

Salvo's on-device engine processes everything locally — no uploads, no account, no tracking of what you make. Read the full Privacy Policy and Terms.
