What Happens When You Merge
- Same format + bitrate: Direct concatenation. No quality loss.
- Different formats: Decoded and re-encoded. Slight loss for lossy formats.
- Different sample rates: Resampled to match.
Tips
- Add crossfade. 0.5-1 second crossfade eliminates harsh cuts.
- Normalize volume. If tracks have different volumes, normalize first.
- Check order. Drag files into correct sequence before merging.
