Frequently Asked Questions
Can I merge tracks that have different sample rates?
Yes. Our engine unifies sample rates through linear interpolation before concatenating the audio streams so the output pitch and playback speed stay perfectly matched.
How does the crossfade transition work?
Crossfading overlaps the end of the previous track with the beginning of the next track, applying an equal-power trigonometric curve so there is no sudden volume drop or clip.
