# DrumSplit — Full LLM Context

> Neural AI-powered drum separation. Split any song into 5 individual drum stems plus a drumless music track.

## Overview

DrumSplit is a web-based audio separation tool at https://drumsplit.io. Users upload a song and get back isolated drum stems (kick, snare, hi-hats, toms, cymbals) plus a music track with all drums removed. All output is 24-bit WAV.

## How It Works

Two-stage neural pipeline:
1. **Stage 1 — Drum Isolation:** Separates drums from the full mix using a neural network, producing an isolated drum bus and a Music stem (original minus drums).
2. **Stage 2 — Drum Splitting:** Splits the isolated drum bus into 5 individual stems: kick, snare, hi-hats, toms, cymbals.

## Separation Modes

- **Natural** (default, free) — Clean, natural separation. Best for acoustic drums, jazz, rock, and general use across all genres.
- **Puncher** (paid only) — Transient enhancement for punchier attack. Optimized for EDM, hip-hop, trap, and pop with heavily compressed mixes.
- **Direct** (paid only) — Skips Stage 1 entirely. User provides an already-isolated drum track or drum bus. Directly splits into 5 individual kit pieces. Perfect for breaking down samples, breaks, and drum bus recordings.
