How to use this workflow
Locate the passage
Count 1–2–3–4 over the full mix before isolating drums. Keep the same count through the section change.
Compare the evidence
Solo the estimated drums and mark main snare accents separately from quieter fills. Return to the full mix to confirm the grouping.
Save a usable reference
If you halve the metronome setting for comfort, write down that counting choice. Do not label it a measured change in the recording.
Worked example and evidence boundary
At 120 quarter notes per minute, one beat lasts 0.5 seconds and a four-beat bar lasts 2 seconds. In a deliberately simplified regular groove, snares on beats 2 and 4 occur at 0.5 and 1.5 seconds. Moving the main snare to beat 3 places it at 1 second. The bar still lasts 2 seconds. These are calculated positions in an invented pattern, not a transcription.
What to verify before using the result
Use the bass, melody and phrase boundaries when two counts both fit. Half-time is a musical interpretation; a BPM detector can suggest a related pulse but cannot decide the intended feel. Avoid changing speed merely to make a displayed BPM agree with your count.
Common questions
Does a half-time feel require a slower export?
No. Preserve playback speed when studying a feel change; the example changes snare placement while keeping the same beat duration.
