In short

  1. Vocal and instrumental separation on the device, with a fast engine and a sharper DTTNet engine

  2. YouTube extraction, trimming and splitting into clips

  3. No cloud, no uploads, no account

What it is

An Android toolkit for pulling sound apart: paste a YouTube link and extract the audio, separate any track into vocals and instrumental, trim a range or split a track into equal clips. Everything is processed on the device.

How it is built

The processing is written in C and C++ and driven from a Kotlin app. Separation offers a fast engine and a sharper one built on DTTNet, output is M4A, MP3 or WAV, and the results live in an app-private library. Keeping it on the device was the point: no cloud, no uploads, no account.
