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 iOS requires iOS 9.0 or higher and works on all devices.
Both versions of Quaver are available now for £0.99 / €1.09 / $0.99.
