FAQ
Questions BPM Calculator owners ask.
- 01
How accurate are the millisecond calculations?
All calculations are rounded to exactly two decimal places to ensure precision for digital audio workstations and sequencers.
- 02
Can I calculate dotted or triplet notes?
Yes, by using the calculate_note_duration capability, you can specify if a note is dotted or part of a triplet subdivision.
- 03
What happens if I provide an invalid BPM?
The capabilities will return a success status of false and provide an error message describing why the calculation failed (e.g., non-positive BPM).
