Duration Calculator

Generate note-value duration tables at any tempo.

What the module shows

The current Duration Calculator supports a common workflow for composers and arrangers: viewing 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.mmm to 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. The table handles the arithmetic without long division, manual rounding, or a 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

Use the Duration Calculator for note-value lookups at a fixed tempo. It shows standard values at 107 BPM for scoring to picture, an eighth-note delay at 128 BPM, or a cue offset from a session start time. For nested-tuplet durations, use Rhythm & Subdivision.
