How to use this workflow
Locate the passage
Locate the downbeat in the full source, then solo the bass estimate to listen for earlier attacks. Do not treat all leading quiet audio as disposable silence.
Compare the evidence
In Audio Trimmer choose a start before the pickup and an end after the complete phrase. Preview both boundaries.
Save a usable reference
Download WAV and listen from the very start. Record the source start and the local downbeat offset beside the file.
Worked example and evidence boundary
For an invented 120 BPM passage, the beat lasts 0.5 s. If the first main downbeat is at source time 12.00 s and a pickup starts an eighth note earlier, the pickup is at 11.75 s. Starting the excerpt at 11.50 s leaves 0.25 s before that pickup. In the excerpt the pickup lands at 0.25 s and the downbeat at 0.50 s.
What to verify before using the result
This is a calculated trimming plan, not a screenshot-based device test. The trimmer keeps a continuous range; it does not add a spoken count-in or reconstruct an already missing pickup. If the source itself begins late, obtain an earlier source rather than hiding the missing entrance with a fade.
Common questions
Can a fade restore a pickup that was cut off?
No. A fade changes the existing boundary; it cannot reconstruct a missing attack. Return to the source and choose an earlier start.
