Open Source Sound Synthesis Software

Project core is fast and accurate resampler, based on FIR-filter, heavily optimized for piecewise-constant functions. Above this is clock-precise AY-3-8910 (YM2149F) emulator. Front-ends are win32 console app, Winamp and GSPlayer plugins

Transform pure innocent audio files, speech, music, etc into unholy demonic abominations. Audio Satanifier 666 is a fun easy-to-use browser-based tool forged in the pits of hell, for voice actors, musicians, sound designers, for memes, for creative projects or anyone else who want to twist their sound into something absolutely diabolical! Layperson friendly - you'll be able to apply cool effects to your audio file even if you know nothing about audio engineering. Theres also a Mini version that has a voice deepening that doesn't slow the speed of the audio. Its more focused on the "satan voice" filter, while the larger default version has 16 different filters you can mix and match. (Source code is included within the html file itself.)

A binary waveform synthesizer derived from and based upon Timewave Zero theory by Terence McKenna. His theory proposes that the structure of time is a complex wave with a scalar potential, and the King Wen sequence of the I Ching is the 64 hexagram code from which the waveform of time is derived; that the King Wen sequence maps the linear progression of the human states of mind, which ultimately substantiates this waveform. This theory is the basis for the well-known novelty computer program he and others had developed. This program synth was made in supercollider.
