The app generates audio test signals including sine, triangle, sawtooth, square, pulse, and various noise types. It supports fixed and sweep frequencies and levels, with adjustable phase shift and multiple sample rates and bit depths.
The app provides a MacCann-style duet concertina simulation with a Treble range from G4 to F#6. Users can transpose the pitch up or down by octave increments and play chords by pressing multiple buttons simultaneously.
Calculate tempo and beat per minute with a tap tempo function. Adjust pre delay, gate, and envelopes. Generate test tones and sine waves. View fretboard and keyboard for scale learning. Play arpeggios and chords.
