Audio Looper and Extender
Calculate a local loop plan without uploading audio or generating an audio file.
A QUICK WALKTHROUGH
How to use this tool
- Enter clip length, loop count and intended fade duration.
- Set a target total length.
- Review the planned repeats, duration and remaining adjustment.
Planning only
This calculator estimates timing and repeat structure. It does not read, upload, edit or generate audio.
Target length
The plan compares the requested target with clip length × loop count and reports the remaining difference. Fade duration is not shown in the results and is not subtracted from the raw clip duration.
GOOD TO KNOW
Common questions
Does it create an audio file?
No. It provides a browser-local timing plan only.
Is my audio uploaded?
No audio is selected or uploaded; all values stay in this browser.
What does the fade value change?
It is an input for your own planning. It is not shown in results, does not model crossfades and does not alter the duration arithmetic.
