Description

It would be very nice to have a window to help do unit conversions, that is, it would have a set of text fields you enter numbers into and it would convert those numbers to different units for you.

Possible unit conversions could include

Pitch

You enter any of the following:

  • Hz
  • MIDI note number
  • Note name and octave
  • Maybe Key number on the piano keyboard (1-88)
  • Maybe Tonic of key, major/minor, temperament, note number in scale, and octave

and it should provide conversions to all of the others. It should use the concert-A setting in the preferences, and remind you what that is.

Also

  • Difference between two notes, in Hz
  • Difference between two frequencies, in semitones/cents

Timing

  • Hz to period (sec/msec)
  • bpm to period
  • bpm to Hz
  • ms to sample count (and vice versa) at file sample rate
  • ms to sample count (and vice versa) at arbitrary sample rate

History

#1 Updated by Chris Cannam about 8 years ago

Unit converter now does basic pitch conversions & beat timing conversions. Doesn't handle scale & key or other temperaments besides 12tET.
