Duration Calculator
Generate note-value duration tables at any tempo.
What the module shows
The current Duration Calculator is built around the workflow composers
and arrangers hit most often: seeing a full table of standard
note-value durations at a chosen tempo. Set BPM and beat unit, and
Calcophony lists each duration in milliseconds and
MM:SS.mmm so you can scan quickly for hit points, rests,
delay times, and bar-length estimates.
What you control
- Tempo and beat unit: choose the reference pulse and Calcophony recomputes the full table immediately.
-
Optional time offset: enter seconds or
MM:SS.mmmto shift every displayed result by a session or cue start time. - Standard note-value table: scan the durations for whole notes, halves, quarters, eighths, tuplet-derived values, and more in one place.
Batch mode
For film scoring and post-production, batch mode tabulates every standard note value at a given tempo in a single pass. At 120 BPM, a whole note is 2000 ms (00:02.000), a quarter is 500 ms (00:00.500), and a 32nd is 62.5 ms (00:00.063). Scan the list to find which division lands closest to a hit point or sync mark: no long division, no rounding, no spreadsheet.
MM:SS.mmm display
Durations are shown in clock-style MM:SS.mmm format
alongside raw milliseconds: a compact elapsed-time readout for hit
points, sample lengths, and region positions.
When to use it
Reach for the Duration Calculator when you need fast note-value lookups at a fixed tempo. Scoring to picture and want to see how long the standard values are at 107 BPM? Tuning a delay to an eighth note at 128 BPM? Checking a cue offset against a session start time? The table gives you the answer immediately. For nested-tuplet durations specifically, use Rhythm & Subdivision.
