Quaver is a utility to assist composers and recording engineers with some maths and musical theory. It features a number of tabs, each dedicated to a particular task. The first deals with tempo, and calculates the delay times and oscilator frequencies that match a particular tempo. This tab also features a metronome. The second tab calculates the relationship between MIDI notes, their fundamental frequencies and their names. The third tab assists you in identifying the notes of a given scale (or mode) and working out how to draw the corresponding key signature. A fourth tab is for converting durations between samples and milliseconds.
Quaver for Macintosh requires OS X 10.13 or higher.
Quaver for iOS requires iOS 15.6 or higher and works on all devices.
Both versions of Quaver are available now for £0.89 / €0.99 / $0.99.
