| Parameter | Setting | Explanation | | :--- | :--- | :--- | | | Chromatic or song key (e.g., C Major) | Restricts correction to valid notes. | | Threshold | 40-60% | Lower = more correction; higher = more original signal. | | Attack | 10-20 ms | Faster = robotic (T-Pain effect); slower = natural. | | Correction Speed | 50-100% | 100% = instant correction; 50% = gradual glide. | | Reference | MIDI note (e.g., C4) | Only corrects notes toward the chosen pitch (optional). |
| Artifact | Cause | Solution | | :--- | :--- | :--- | | "Chipmunk" warble | Correction speed too fast on vibrato | Increase Attack time to 20-30 ms. | | Hollow/phase sound | Applying pitch correction twice | Undo and reapply on a fresh copy of the track. | | Robotic glides | Scale set to Chromatic | Set to a specific major/minor scale. | | Silence/pops at edges | Zero-crossing not aligned | Before selecting, go to Edit → Zero Crossing . | how to auto tune in audacity
