Demlo is a music library organizer. It can encode, fix case, change folder
hierarchy according to tags or file properties, tag from an online database,
copy covers while ignoring duplicates or those below a quality threshold, and
much more. It makes it possible to manage your libraries uniformly and
dynamically. You can write your own rules to fit your needs best.
Demlo can address any of these recurring music library issues (and much more):
- Fix the lack of folder structure.
- Normalize tags, fix their case, chose which tags to keep and which to discard.
- Handle lossy and lossless audio differently.
- Handle mp3 id3tags hell…
- Handle multiple covers, whether embedded and/or external, resize covers,
discard bad quality ones.

Cloud Seed ~ Algorithmic Reverb
Cloud Seed is an algorithmic reverb plugin built in C# and C++ for emulating huge, endless spaces and modulated echoes. The algorithms are based on the same principles as manu classic studio reverb units from the 1980’s, but Cloud Seed does not attempt to model any specific device, or even to be a general-purpose reverb plugin at all. It is best employed as a special effect, for creating thick, lush pads out of simple input sounds.

CHOW ~ Maximally Truculent Distortion
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!

Radio Tray ~ Linux Radio Player
Radio Tray is an online radio streaming player that runs on a Linux system tray. Its goal is to have the minimum interface possible, making it very straightforward to use. Radio Tray is not a full featured music player, there are plenty of excellent music players already. However, there was a need for a simple application with minimal interface just to listen to online radios. And that’s the sole purpose of Radio Tray.
Features:
- plays most media formats (based on gstreamer libraries)
- drag & drop bookmarks support
- easy to use
- supports PLS playlist format (Shoutcast/Icecast)
- supports M3U playlist format
- supports ASX, WAX and WVX playlist format
- extensible by plugins

Argotlunar ~ Granulator VST / AudioUnit
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.

andes ~ Perlin Noise Sound Synthesiser
Andes is a standalone software synthesiser, or plugin, in early stages of development. The core of Andes is an original oscillator which uses a pseudo-3D version of Perlin Noise to produce distinctively digital sound.

OwlPlug ~ Audio VST Plugin Manager
OwlPlug is a desktop application for Windows and Mac that simplifies VST Plugin management and installation. User installed plugins are automatically discovered and new plugins can be installed through Stores. The default store called OwlPlug Central delivers quality plugins made by the community. Any third party plugin distributors can set up a compatible Store and let owlplug interact with it. OwlPlug is still in a beta stage, all kind of feedbacks are welcomed.

ShuiCast ~ Foobar / WinAmp Streaming
ShuiCast is a plugin for both Winamp and Foobar2000 that provides the ability to broadcast various audio formats to a few of the major broadcasting servers. It is a continuation of the Oddcast/Edcast streaming software that can stream to either Icecast or Shoutcast servers, integrating changes made by the AltaCast and Edcast-Reborn spinoffs.
Features:
- Stream to IceCast or ShoutCast
- Support for Ogg Vorbis, LAME (lame_enc.dll), and AAC (libfaac.dll) – note lame_enc.dll and libfaac.dll must be downloaded separately in order to use these formats
- Multiple encoders (you can simultaneously broadcast in multiple formats at the same time)
- Standalone application as well as plugin for Winamp, RadioDJ and Foobar2000
- Metadata not only from media player (i.e. Winamp) but also from a file, a URL or a window
- Peak and RMS Meter
- Live Recording (you can switch on/off without disconnecting the encoder)
ADLplug ~ FM Chip Synthesizer
Synthesizer plugin for ADLMIDI and OPNMIDI (VST/LV2). This software package provides FM synthesizer plugins, based on OPL3 and OPN2 sound chip emulations.
The emulations and the drivers are provided by libADLMIDI and libOPNMIDI.
