Quaver

Quaver is a musical calculator and look-up tool for recording engineers and composers. It can calculate the delay times and oscillator frequencies that match a given tempo to help keep things in sync. Its pitch tool can tell you the fundamental frequency of any note in the MIDI range -- or perform the reverse calculation. Finally, the scale tool can tell you the notes that make up a given scale and draw the key signature.

Version 1.5:

• Quaver can now convert time durations between milliseconds and samples at a variety of sample rates.
• Other minor improvements.

Requirements for Quaver

• OS X 10.6 or later
