How to use this workflow
Copy the actual requirement
Record maximum duration, required introduction, allowed edits and delivery format before trimming.
Budget the full file
Subtract every required non-performance segment and an explicit safety margin from the limit.
Trim and verify the delivery
Use Audio Trimmer for a continuous excerpt, then inspect the exported file from beginning to end. Convert only if the requested format requires it.
An invented 90-second delivery budget
Suppose an organizer permits a 90-second file and requires a 4-second introduction. Reserve 1 second of final silence and 0.5 seconds of margin. The performance budget is 90 − 4 − 1 − 0.5 = 84.5 seconds. These are hypothetical requirements, not rules for a real audition.
If the desired performance starts at source time 32.250 seconds, its planned end is 116.750 seconds. Trimming that source range yields the performance excerpt only. This site’s Trimmer does not prepend a separate introduction file; assemble separate sources externally if the organizer allows that edit.
Swipe or scroll sideways to read all columns.
| Component | Duration | Cumulative budget |
|---|---|---|
| Introduction | 4.0 s | 4.0 s |
| Performance | 84.5 s | 88.5 s |
| Final silence | 1.0 s | 89.5 s |
| Unused margin | 0.5 s | 90.0 s limit |
Inspect the file the reviewer will receive
Audio Trimmer outputs WAV. If MP3 is required, convert the saved WAV and check the duration of that final MP3 too; codec padding and player rounding can affect a displayed duration. Do not infer compliance from an editor selection label alone.
Listen to the first and last phrases for abrupt cuts and missing endings. A faster playback rate changes the performance and may be disallowed, so prefer a musically complete shorter excerpt or an authorized edit rather than speeding it up merely to fit. Keep the original recording and a note of the final filename and exact duration.
