Differential Audio Inc.'s mission is to push the limits of audio synthesis via unique architectures.

We believe that our products will sound different and can be a tool for new avenues of expression.

Patent Pending

Coming 2025

The Eosynth is a powerful desktop additive synthesizer that uses up to 8192 sine waves to build unique and interesting sounds not available using subtractive synthesis, via an intuitive interface.

Currently in beta testing and scheduled for product release in early 2025.

Please view the Eosynth product page for product details.

Powerful GUI

Simplify additive synthesis sound design with the Eosynth's intuitive user interface. Add oscillators and define their partial's envelopes, add chords, create stereo or quadraphonic sounds.

Partial Envelopes

Generate per partial envelopes for each of the 32 to 128 sine waves per additive oscillator. Control amplitude, frequency deviation and AM and FM modulation.

Real Time FFT

View your sound in the frequency domain to visualize the components of the sound you hear.

Partial Enables

Select which partials you want to hear, which leads to different sound spaces than are availible with subtractive synthesis.
