Crystal Mixer ~ ASIO Driver / OpenAL Output


Crystal Mixer is based on the OpenAL engine surround sound mixer. It supports up to 8 direct output and input channels and up to 18 output channels through a 3D mixer. It works through the ASIO Driver API for versatility. It’s possible to use up to 15 customizable auxiliary effects. It is also possible to enable hardware acceleration with some sound cards.

Features:

  • Multichannel surround sound support
  • Up to 8 native input and output channels
  • Up to 18 output channels mixing in 3D space
  • Auxiliary EFX and EAX20 effects
  • Reverb, Echo, Chorus, Flanger and others effects
  • Sound rotation and position changing
  • Source positions visual control with 3D view (OpenGL required)
  • Hardware Acceleration with native OpenAL driver
  • 3D movement effects

SpatGRIS ~ Multichannel Composition


The SpatGRIS is a plugin (Mac AU/VST and VST Windows format) designed to compose multichannel space. It allows the user to spatialize the sound in 2D (up to 16 speakers) or in 3D (up to 128 speakers) under a dome of speakers (with the ServerGRIS, available also on SourceForge). It includes two audio modes, — Free Volume and PanSpan — and one OSC mode. SpatGRIS is a fusion of two former plugins by the GRIS: OctoGRIS and ZirkOSC with a lot of new features. Automated Trajectories are included. It is possible to control it from external controllers such as Joystick, iPad or Leap Motion.

Features:

  • Three modes: Free Volume, Pan Span, OSC Spatialization
  • Automated Trajectories
  • Up to 16 outputs in audio mode
  • OSC Mode to control the ServerGRIS
  • External controllers: Joystick, iPad. Leap Motion

Aften ~ Create Stereo & Multi-channel Audio


Aften is an audio encoder which generates compressed audio streams based on ATSC A/52 specification. This type of audio is also known as AC-3 or Dolby® Digital and is one of the audio codecs used in DVD-Video content.

Features:

  • Converts PCM source audio into AC-3 audio
  • Allows for setting of production metadata such as dialogue level, downmix levels, and extended bitstream information
  • Supports RAW, WAV, AIFF, and CAFF input file formats
  • Supports single multi-channel or multiple mono source files
  • Includes several optional pre-processing filters
  • Uses multi-threading and assembly optimizations to speed up encoding

foo_dsp_xover ~ Foobar2000 Digital Crossover


foo_dsp_xover is a software digital crossover implementation that I have been working on for a while in my spare time as a hobby. It is a Foobar2000 audio player plugin that implements this digital crossover to achieve active multi-amplification.

This software needs to run on a WinXP PC equipped with a multi-channel sound card (e.g. 5.1 or 7.1 surround sound card) feeding the various voices of a multi-amplifier and loudspeaker active configuration set-up.

ANMP ~ Another Nameless Music Player


ANMP aims to be a versatile but lightweight audio player, just as the other hundred thousands out there. It is written in C++11. As being only a frontend, ANMP itself doesn’t know anything about audio formats and how to decode them. That’s why it uses 3rd party libraries to decode them. By using VgmStream, GameMusicEmu, LazyUSF and supporting looped songs natively, ANMP is esp. suited to play various audio formats from video games. Moreover it supports Looped Midi Tracks.

Main Features:

  • muting multichannel audio files
  • gapless playback (for most streamed audio formats)
  • arbitrary (forward) looping of songs (i.e. even nested loops)
  • synthesizing MIDI files using fluidsynth
  • multi-channel audio rendering
  • overlapping notes do not kill each other
  • unrolling looped MIDI tracks
  • volume response compatible to N64’s software synth
  • supports an IIR lowpass filter compatible to Rareware‘s N64 games (Conkers Bad Fur Day, Jet Force Gemini)
  • support for cue sheets
  • support for audio normalization based on EBU R 128
  • exposes basic commands via D-Bus

ChucK ~ Music Programming Language


ChucK is a programming language for real-time sound synthesis and music creation. It is open-source and freely available on MacOS X, Windows, and Linux. ChucK presents a unique time-based, concurrent programming model that’s precise and expressive (we call this strongly-timed), dynamic control rates, and the ability to add and modify code on-the-fly. In addition, ChucK supports MIDI, OpenSoundControl, HID device, and multi-channel audio. It’s fun and easy to learn, and offers composers, researchers, and performers a powerful programming tool for building and experimenting with complex audio synthesis/analysis programs, and real-time interactive music.
