SINE Isochronic Entrainer is a Free and Open Source Brainwave Entrainment application for PC, Android, and HTML5. Brainwave Entrainment is the practice of using sounds, visual stimuli or even electromagnetic fields to alter the frequency of brainwaves. It can be done for several reasons: people with insomnia can take great benefit from it, but it can also be used to improve your attention span, and even simulate the effects of some recreational drugs. The effect is not permanent, and fades away in less than a minute after the stimuli is removed. Isochronic tones are a commonly used aural stimuli for Brainwave Entrainment, consisting of short pulses of a sine wave, varying in frequency. Unlike binaural beats, isochronic tones can be played on speakers. The Player supports touchscreens and high resolution displays. Includes a graphical editor for making presets, with a manual.

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.)

Standing Wave 3 is an AS3 code library designed for high level control of the Flash Player's SampleDataEvent API for streaming audio output. It is based on a subset of the audio engine used by the Noteflight Score Editor (see http://www.noteflight.com). - SW1 was never released. - SW2 was a pure AS3 project open sourced by Joe Berkovitz - SW3 is SW2 extensively refactored by Max Lord Standing Wave 3 is very much like SW2, except that all of its core sample storage and manipulation routines have been rewritten with Adobe Alchemy to make them oodles more efficient. The goal of StandingWave is to encapsulate the following kinds of objects, permitting them to be easily chained together and combined to produce complex, dynamic audio output: - audio sources (MP3 or WAV files, algorithmic sound generators...) - audio filters (echo, envelope shaping, equalization...) - timed sequences of audio sources, which may be hierarchically composed.
