Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package.
The primary platform for running Ecasound is GNU/Linux. Ecasound can also be run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris. Limited support for Windows is available through Cygwin.
caotica2 is a “noise design application”, featuring audio synthesis and effects. The goal of this experimentally designed application is to generate new sounds and noises, and also to alter wave files using simple and complex mathematical effects. The results may sound “noisy” and chaotic and, actually, they are, although rather predictable when getting used to the application. caotica2 is a source of “rough sound material” for the use of experimental composers.
CHOW is a digital distortion effect designed for maximum truculence, somewhere between a true half-wave rectifier and a noisy vintage compressor. Useful for mixing guitars, drums, even vocals when a heavily degraded sound is desired. Feel free to build and use for your own enjoyment!
Acon Digital Multiply is a free and versatile chorus effect with a unique twist. Each simulated voice is processed with a phase randomizing filter so that unpleasant comb filter effects are avoided. The effect can be used to simulate the effect of several performers playing the same tones simultaneously, to widen the spatial image or to create special effects for sound design. Multiply can simulate up to 6 additional voices and both the pitch and the loudness of the voices can be modulated. There is also an integrated equalizer consisting of low cut, low shelf, high shelf and high cut filters that can be applied to the effect signal. An integrated pre-delay section makes it possible to create modulated and diffuse echo effects.

Argotlunar is a tool for creating surreal transformations of audio streams. Specifically, it is a real-time delay-line granulator. It disintegrates an audio stream into short samples (grains). Each grain can have random settings of amplitude, panning, duration, delay, pitch, glissando, filter and envelope. The output of all grains is mixed together into a stream which can be fed back into the main input.
Time-related parameters can be synced to the host tempo, for rhythmic and pulsing textures. Pitch-related parameters can be quantized for harmonic and melodic effects. Feedback can create chaotic, densely layered, and distorted sounds.
Most of the parameters can be correlated. Examples:
- Filter cut-off correlated with pitch: Higher filter cut-off for grains with higher pitch, and vice versa.
- Grain duration correlated with panning: Grains with shorter duration panned to the centre of the stereo field, and grains with longer duration panned wide in the stereo field.
SoundBible.com offers thousands of free sound effects, sound clips, and straight up sounds. These sounds can be used in a variety of sound projects including Video Sound Scores, Movie Scoring, Game Design, Powerpoint Presentations, Prank Calls, Sound Boards, and the list goes on. SoundBible.com is a great source for copyright free sounds.
Why are these sounds free? Well for a few reasons really:
- Our project benefits teachers, students, faculty, and starving artist. They couldn’t afford to buy them so we are forced to give them away for free. 🙂
- The Royalty Free Sounds section consist of Creative Commons and Public Domain works
- The owners of SoundBible.com were taught to share by their parents. Isn’t that what your parents taught you?
- Because Free is way cooler than Fee. That one letter “r” makes a world of difference
Can these sounds be used commercially? The Royalty Free Sounds can indeed be used for commercial uses. The free sounds can only if they are under the Creative Commons Attribution, or Public Domain License.
Rakarrack is a richly featured multi-effects processor emulating a guitar effects pedalboard. Effects include compressor, expander, noise gate, graphic equalizer, parametric equalizer, exciter, shuffle, convolotron, valve, flanger, dual flange, chorus, musical delay, arpie, echo with reverse playback, musical delay, reverb, digital phaser, analogic phaser, synthfilter, varyband, ring, wah-wah, alien-wah, mutromojo, harmonizer, looper and four flexible distortion modules including sub-octave modulation and dirty octave up. Most of the effects engine is built from modules found in the excellent software synthesizer ZynAddSubFX. Presets and user interface are optimized for guitar, but Rakarrack processes signals in stereo while it does not apply internal band-limiting filtering, and thus is well suited to all musical instruments and vocals. Rakarrack is designed for Linux distributions with Jack Audio Connection Kit.
Step into music production with KOMPLETE START – a curated selection of studio-quality instruments, effects, utilities, loops, and samples for the low price of nothing at all. Play over 2,000 customizable sounds – drums and percussion, bass, acoustic instruments, synths, pads and atmospheres, effects, and more. And did we mention it’s free?
CAPS is a collection of audio plugins comprising basic virtual guitar amplification and a small range of classic effects, signal processors and generators of mostly elementary and occasionally exotic nature.
The plugins aim to combine the highest sound quality with computational efficiency and zero latency*.
