How to use this workflow
Locate the cue
Listen for the first intentional click or spoken count. A waveform alone cannot tell you whether a small sound is useful.
Keep a small lead before it
Set the start before the first cue and the end after the wanted passage. Use zero fades for the first comparison.
Export and count again
Select Preview result, download WAV, then count the saved cue through the music entrance. Keep the original file.
The count-in is content, even when the music has not started
Automatic silence removal can confuse quiet cues with unwanted space. This trimmer does not perform silence detection: you choose one continuous interval using millisecond fields or the waveform. That manual boundary lets you preserve a breath, stick click or pickup that matters to the entrance.
For a rehearsal handoff, identify the first useful cue and the first musical entrance separately. Ask whether someone opening the saved file has enough information to enter on time. Beginning exactly at the music can make the export shorter while making the practice task harder.
Original fixture: four cues followed by a tone entrance
Our authored six-second mono fixture has silence before 1.000 s, four synthesized clicks at 1.000, 1.500, 2.000 and 2.500 s, and a held tone beginning at 3.000 s. It is a timing demonstration, not a recorded musician.
The actual browser trimmer export uses Start = 900 ms, End = 6000 ms and no fades. It contains 244,800 frames at 48 kHz, or 5.100 s. Subtracting the 0.900 s start moves the first cue to 0.100 s and the entrance to 2.100 s; the 0.500 s gaps remain intact.
Swipe or scroll sideways to read all columns.
| Event | Source position | Saved position |
|---|---|---|
| First cue | 1.000 s | 0.100 s |
| Fourth cue | 2.500 s | 1.600 s |
| Tone entrance | 3.000 s | 2.100 s |
Do not fade away the cue you wanted to keep
First export with Fade in = 0. If there is a boundary click, move the start into quieter space or try a brief fade that finishes before the first cue. A fade operating across the cue can weaken it; it cannot restore audio that was excluded by the selection.
For this fixture, the retained 100 ms lead is an authored choice. It is not a universal requirement for every recording. Spoken counts and soft pickups may need more context, so use listening and the intended player rather than copying the number blindly.
Confirm the handoff format and the complete ending
The trimmer downloads WAV. If the recipient needs MP3, convert a copy afterward and check its entrance again. Retain the WAV for subsequent editing and give the copy a name that indicates the preserved count-in.
This workflow does not add a click, duplicate bars or synchronize a changing performance to a metronome. If the source contains no useful count-in, create one in an external editor rather than assuming trimming will generate it.
Common questions
Will the trimmer remove silence automatically?
No. It retains the single interval you select.
Should I always leave 100 ms?
No. That is the fixture setting. Leave enough context for your actual cue and audition the saved result.
