Step-by-Step Process
Step 1: Choose Your Songs
Pick songs with:
- Similar BPM (within 10 BPM)
- Compatible or same key
- Strong vocal melody on song A
- Strong instrumental on song B
Example combo:
- Vocals: "Someone Like You" (Adele, 67 BPM, A major)

Step 2: Isolate Vocals and Instrumentals
Use StemSplit to separate:
For Song A (source of vocals):
- Upload to StemSplit
- Select "Vocals Only"
- Download acapella
For Song B (source of instrumental):
- Upload to StemSplit
- Select "Instrumental Only"
- Download backing track
Step 3: Match Tempo
Both tracks must be same BPM:
In Audacity:
- Effect → Change Tempo
- Adjust percentage
- Preview and apply
In DAW:
- Enable "Warp" or "Flex Time"
- Set both tracks to same BPM
Step 4: Match Keys
Vocals and instrumental should be in compatible keys:
Check keys:
- Use online key detector
- Or trust your ear
Adjust if needed:
- Effect → Change Pitch (Audacity)
- Transpose function (DAW)
Key compatibility chart:
- C major ↔ A minor
- G major ↔ E minor
- D major ↔ B minor
- Etc.
Step 5: Align and Mix
Arrangement:
- Import both tracks into DAW/Audacity
- Line up downbeats
- Adjust vocal placement
- Try different starting points
Mixing tips:
- Vocals slightly louder than instrumental
- Add reverb to blend vocals
- EQ to prevent frequency clashes
- Compress for consistent levels
Step 6: Add Transitions
Make it interesting:
- Drop instrumentals during vocal highlights
- Switch between two instrumentals
- Add effects on transitions
- Build energy throughout
Step 7: Export
Settings:
- WAV (uncompressed) for further editing
- MP3 320kbps for sharing
- Normalize to -1 dB
Pro Tips
Finding Compatible Songs
Use These Tools:
- Mixed in Key (key detection)
- WhoSampled.com (find similar songs)

Tempo Tricks
If BPMs are different:
- Speed up slower track
- Slow down faster track
- Change both to middle BPM
Formula:
New BPM = Original BPM × (Desired BPM ÷ Original BPM)
