# Stem Separation in REAPER: Complete Guide

REAPER doesn't have built-in stem separation, but you can integrate AI tools and plugins. Here's how.

## REAPER + AI Stem Separation

**Two approaches:**
1. Pre-process stems with AI → Import to REAPER
2. Use VST plugins inside REAPER

## Method 1: Pre-Process with AI (Recommended)

**Workflow:**
1. Export track from REAPER
2. Process with [StemSplit](/stem-splitter)
3. Import separated stems back
4. Continue editing/mixing

**Advantages:**
- Best quality (latest AI)
- No CPU load during mixing
- Clean stem files

### Step-by-Step

**1. Export From REAPER:**
- File → Render
- WAV format
- Original sample rate

**2. Separate Stems:**
- Upload to [StemSplit](/stem-splitter)
- Select 4-stem separation
- Download vocals, drums, bass, other

**3. Import to REAPER:**
- Drag stems into project
- Line up with original timing
- Label tracks clearly

**4. Mix:**
- Individual stem processing
- Effects per stem
- Final master

## Method 2: VST Plugins in REAPER

**Available plugins:**
- iZotope RX Music Rebalance ($399+)

2. Place in VST folder
3. REAPER → Preferences → Plugins
4. Rescan VST paths
5. Add plugin to FX chain

**Limitations:**
- Expensive plugins required
- CPU intensive
- Real-time processing slow
- Lower quality than offline AI

## Workflow Comparison

| Method | Quality | Speed | CPU | Cost |
|--------|---------|-------|-----|------|
| [StemSplit](/stem-splitter) + REAPER | Excellent | Fast | Zero | $0.10/min |

## REAPER Workflow Tips

**Organize stems:**

## Recommended Setup

**For professional results:**

1. **Stem separation:** [StemSplit](/stem-splitter) (best quality)
2. **DAW:** REAPER (editing/mixing)
3. **Monitoring:** Good headphones
4. **Export:** WAV 24-bit

## FAQ

### Can REAPER separate stems natively?

No. Use external AI tools like [StemSplit](/stem-splitter) then import results.

### Do I need expensive plugins?

No. Pre-process with [StemSplit](/stem-splitter) ($0.10/min) instead of buying $399+ plugins.

### What sample rate should I use?

Match your project sample rate (usually 44.1kHz or 48kHz).

## Conclusion

**Best workflow for REAPER users:**
1. Export track from REAPER
2. Separate stems with [StemSplit](/stem-splitter)
3. Import separated tracks
4. Mix in REAPER

Faster, cheaper, and better quality than VST plugins.
