Re:Pitch is a small, browser-based tool I built to recreate an old sampling workflow in a fast, frictionless way.

Speeding up samples before loading them into a sampler is a technique that goes back to early hardware like the Emu SP-1200 and Akai MPC60. Originally, it was a workaround for limited memory. Today, it’s still useful — not out of necessity, but for the sound and the feel it creates.

I made Re:Pitch because I wanted a simple way to apply that technique without opening a DAW or repeating the same resampling steps over and over.

What It Is

Re:Pitch is a drag-and-drop web app that lets you change the speed and fidelity of audio files before they’re loaded into a sampler.

You can choose clean, CD-quality output or deliberately degraded settings inspired by classic samplers like the SP-1200 or Casio SK-1. The result is a pre-processed sample that’s meant to be pitched down and played on hardware.

How It Works

The tool runs entirely in the browser using the Web Audio API. All processing happens client-side, so your audio files never leave your computer.

It’s intentionally limited and focused. The goal isn’t to replace a DAW, but to remove a repetitive step from the creative process and keep momentum going.

Why I Made It

I built Re:Pitch after getting tired of manually speeding up and resampling sounds for my Teenage Engineering EP-133 KO II in Ableton.

It reflects the kind of tools I like to make and use myself: small, specific, and designed around real workflows rather than feature lists.
