BiSynth

By David CLIFTON

This app is only available on the App Store for iOS devices.

Description

BiSynth is a virtual analog synthesizer. The audio output is produced by a pair of computed waveforms modulated by a note envelope.

The left and right output channels of the iPhone may be given different waveforms from a selection available on the settings screen. The note envelopes are the same on each channel, and are computed from attack, decay, sustain, and release settings, also on the settings screen.

A frequency difference between left and right channels can be set in Hertz (cycles per second) or halfsteps (the smallest musical interval on the piano). Halfstep differences are useful for exploring harmonious and not so harmonious intervals. The differences in Hertz can generate vibrato of different frequences, as well as a kind of poor mans surround sound simulation.

A variable cutoff, resonant filter allows the user to adjust the sound of each pair of waveforms, and a pan control allows the left and right channels to be mixed in different proportions.

The ouput sounds different with earphones than with speakers. This reflects the fact that the brain mixes sounds differently than the room. Some experimenters discovered that brain waves are sometimes entrained at the frequency difference between and left and right ear tones.

When you fiddle around with the settings and produce a sound that you like; you can save it in a database of presets.

BiSynth provides a choice between a standard, 5 octave keyboard, which scrolls from side to side, and a scrolling Janko keyboard with the same number of notes.

What's New in Version 1.2

A 5 octave scrollable Janko keyboard has been added as a user selectable option
