## Frequently asked questions

### When should I use time stretching instead of resampling?

Use time stretching when pitch should remain stable while duration or tempo changes. Choose resampling when speed and pitch should change together.

### Is a looper different from concatenating a clip?

Yes. audio-looper targets a seamless musical or ambient join; audio-loop-concat simply repeats the complete file.

### How do I align a remix to another track?

Start with audio-beat-matcher, then use a pitch-preserving tempo or stretch tool and listen for transient drift.
