Duration Calculator

Generate note-value duration tables at any tempo.

Calcophony Duration Calculator showing note values converted to milliseconds and MM:SS.mmm elapsed-time display

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

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.
