Audio loop duration calculator with gaps and crossfades
Read a local loop length or enter it manually, then calculate repeat or target duration with real gaps and crossfades between plays.
Choose a local audio file or enter its duration, add any gap or crossfade, then calculate total time or the complete loops that fit a target.
Result
Use the real loop duration
Choose a local file to read its duration in the browser or enter the length manually. Calculate by repeat count or target duration, then include the gap or crossfade applied at every transition instead of assuming every player is perfectly gapless.
Rehearse the actual player
The result models the transition values you enter, but encoder padding and player behavior can still differ. Test the same file, loop mode, crossfade, output route, and target program moment before relying on an exact endpoint.
