## Overview

StemSplit is a web-based audio stem separation service. Users can upload audio files or paste YouTube URLs to extract:

- **Vocals** - The singing/voice track
- **Instrumental** - Everything except vocals (also called "backing track" or "karaoke version")
- **Drums** - Isolated drum and percussion tracks
- **Bass** - Isolated bass guitar/synth bass
- **Guitar** - Isolated guitar tracks (6-stem mode)
- **Piano** - Isolated piano/keyboard tracks (6-stem mode)
- **Other** - Remaining instruments

## Key Features

### Vocal Removal
Remove vocals from any song to create karaoke tracks or instrumental versions. Uses AI to cleanly separate the voice from the backing music while preserving audio quality.

### 4-Stem Separation
Split audio into four separate tracks:
- Vocals
- Drums
- Bass
- Other (guitars, keyboards, synths, etc.)

### 6-Stem Separation
Split audio into six separate tracks for more granular control:
- Vocals
- Drums
- Bass
- Guitar
- Piano
- Other

### YouTube Integration
Process YouTube videos directly by pasting the URL. StemSplit downloads the audio and processes it automatically. Maximum video duration: 120 minutes.

### Multiple Output Formats
Export stems in your preferred format:
- **WAV** - Lossless, highest quality, larger files
- **MP3** - Compressed (320kbps), smaller files
- **FLAC** - Lossless compression, good balance of quality and size

### REST API
Full programmatic access for developers. Create automated workflows, integrate with existing tools, or build custom applications.

### Free Credits on Signup
New users receive **5 free minutes** of audio processing when they sign up — no credit card required. That's enough to process about 1-2 full songs.

---

## How It Works

1. **Upload Audio**: Upload an audio file (MP3, WAV, FLAC, M4A, OGG, WebM) or paste a YouTube URL
2. **Choose Output**: Select what stems you want (vocals only, instrumental, both, 4-stems, or 6-stems)
3. **Select Quality**: Choose processing quality (Fast, Balanced, or Best)
4. **Process**: AI model separates the audio into individual stems
5. **Download**: Download your separated stems in your chosen format

Processing time varies based on audio length and quality setting:
- Fast: ~20 seconds per minute of audio
- Balanced: ~40 seconds per minute of audio
- Best: ~60 seconds per minute of audio

---

## Pricing

StemSplit uses pay-as-you-go credit-based pricing. Credits never expire.

### Free on Signup

New users get **5 free minutes** when they sign up — no credit card required.

### Credit Packages

| Package | Minutes | Price | Per Minute |
|---------|---------|-------|------------|
| Starter | 10 min | $2 | $0.20 |
| Standard | 30 min | $5 | $0.17 |
| Pro | 100 min | $12 | $0.12 |
| Studio | 300 min | $30 | $0.10 |

### How Credits Work

- Credits are measured in processing minutes
- 1 credit = 1 second of audio processed
- A 3-minute song uses 180 credits (3 minutes)
- Output type and quality do not affect credit usage
- Only successful jobs consume credits

### Referral Program

Get **5 free minutes** when friends sign up with your referral link.

### Enterprise
