The coarse envelope check puts the offset near , but the fine correlator locked to . On steady pitched sources this can happen if the correlator snaps to a pitch-period sidelobe.
- Try re-bouncing a section with a clear transient (rim hit, consonant, kick).
- Verify by ear with a null test in your DAW before applying.
- Or accept the envelope value as a starting point and fine-tune.
