AudioMass lets you record, or use your existing audio tracks, and modify them by trimming, cutting, pasting or applying a plethora of effects, from compression and paragraphic equalizers to reverb, delay and distortion effects. AudioMass also supports more than 20 hotkeys combinations and a dynamic responsive interface to ensure ease of use and that your productivity remains high. it is written solely in plain old-school javascript, weights approximately 65kb and has no backend or framework dependencies.
The Computer Music Toolkit (CMT) is a collection of sixty five LADSPA plugins for use with software synthesis and recording packages on Linux
You have the need for professional and state-of-the-art audio plug-ins – but don’t have thousands of bucks to spend on it? Then we believe you will love Calf Studio Gear! Focused on high-quality sound processing and a highly usable interface Calf Studio Gear is designed to give you a professional production environment for your open source operating system. Play your SF2 sample banks, create filthy organs, fatten your sounds with phasers, delays, reverbs and other FX, process your recordings with gates, compressors, deesser and finally master your stuff with multiband dynamics – for free! Calf Studio Gear is available exclusively for LINUX-based operating systems and runs as a stand-alone effect rack connectable through Jack sound server or as plug-ins in every audio host that is able to fire up LV2 compliant devices, e.g. the highly recommended Ardour Audio Workstation

LFX-1310 is a free plug-in multi-effector including 24 types of algorithm and 3 serial slots. This freeware is the stand-alone version of Effecting Module of Ravity-S & Ravity-R. Every algorithm realizes the very effect you have on your mind, and is fully optimized for low CPU load.
CP-GFX is simply a Cross Platform Guitar Effect Processor. The aim of the project is to create an extensible and easy to use program which is easy to port to different platforms and operating systems. Currently in development are Linux x86 and Win32 builds.
For the Linux build the primary audio API in use is JACK, which allows CP-GFX to work along side and with other programs, such as Ardour, or any other software using JACK without any fuss or problems.
LAoE means Layer-based Audio Editor, and it is a rich featured graphical audio sample-editor, based on multi-layers, floating-point samples, volume-masks, variable selection-intensity, and many plugins suitable to manipulate sound, such as filtering, retouching, resampling, graphical spectrogram editing by brushes and rectangles, sample-curve editing by freehand-pen and spline and other interpolation curves, effects like reverb, echo, compress, expand, pitch-shift, time-stretch, and much more… And it is free of charge, under GPL license!

CheeseTracker is a software sampler and step-based sequencer. It allows a musician to turn single-note samples into instruments capable of covering three or four octaves (by playing the samples at different speeds, resulting in different pitches). In addition, it is possible to take a collection of samples that are recorded at different octaves, and combine them into a single “instrument,” allowing for even more octaves without sampling artifacts.
Using the Pattern Editor, it is possible to compose songs with these instruments that the computer plays automatically. The Pattern Editor allows the user to arrange samples in several independant channels, so that many samples can play simultaneously. These songs, and the samples which comprise their instruments, can be saved together in one-file archives called modules.
CheeseTracker imposes no limits on the length of the samples used. As a result, it can be used as a mixer as well as a sampler/sequencer. Effects such as reverb can be applied to each sample individually, eliminating the need for expensive pedals.
AUBE is a system for sound generation and processing. You can process audio on the fly by setting up arbitrary configurations of sound generators, sequencers and effects modules, through which sound is played, filtered, and recorded.
