A programmable audio generator intended as an aural aid to meditation, implementing the binaural beat principle as described in Gerald Oster’s Oct. 1973 Scientific American article “Auditory Beats in the Brain.”

The Apple Lossless Audio Codec (ALAC) is an audio codec developed by Apple and supported on iPhone, iPad, most iPods, Mac and iTunes. ALAC is a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file.
The Apple Lossless Audio Codec project contains the sources for the ALAC encoder and decoder. Also included is an example command line utility, called alacconvert, to read and write audio data to/from Core Audio Format (CAF) and WAVE files. A description of a ‘magic cookie’ for use with files based on the ISO base media file format (e.g. MP4 and M4A) is included as well.

This package contains ALAC code used in foobar2000 / foobar2000 Mobile; derived from Apple’s public ALAC code release.
MOC (music on console) is a console audio player for LINUX / UNIX designed to be powerful and easy to use.
You just need to select a file from some directory using the menu similar to Midnight Commander, and MOC will start playing all files in this directory beginning from the chosen file. There is no need to create playlists as in other players.
However if you want to combine some files from one or more directories on one playlist, you can still do it. The playlist will be remembered between runs or you can save it as an m3u file and load it whenever you want.
Need the console where MOC is running for more important things? Need to close the X terminal emulator? You don’t have to stop listening to the music – just press q and the interface will be detached leaving the server running. You can reattach it later, or you can attach one interface in the console, and another in the X terminal emulator, no need to switch just to play another file.
MOC plays smoothly, regardless of system or I/O load because it uses the output buffer in a separate thread. It provides gapless playback because the next file to be played is precached while the current file is playing.
Internet streams (Icecast, Shoutcast) are supported.
Amsynth is an easy-to-use software synth with a classic subtractive synthesizer topology.
- Dual oscillators (sine / saw / square / noise) with hard sync
- 12/24 dB/oct resonant filter (low-pass / high-pass / band-pass / notch)
- Mono / poly / legato keyboard modes
- Dual ADSR envelope generators (filter & amplitude)
- LFO which can modulate the oscillators, filter, and amplitude
- Distortion and reverb

Implementation of a K-System meter according to Bob Katz’ specifications.
K-Meter supports mono, stereo and 5.1 surround sound signals. All meters have been thoroughly validated. The average meter reads either RMS levels or ITU BS.1770-1 loudness weighted levels.

Open source plugin to transfer real-time audio over a network. Hyperspace travel for your audio.

FlacSquisher converts a library of FLAC files to MP3, Opus, or Ogg Vorbis format, maintaining the directory structure in the original library. That way, you can maintain your FLAC files for home listening, and easily convert them to MP3, Opus, or Ogg format for mobile use, where storage space is more often tightly constrained.
Features:
- Converts to MP3 or Ogg Vorbis
- Maintains directory structure from original library
- Takes advantage of multicore processors
- Can copy or ignore files by extension (album art, log files)
- Ignores files already encoded previously
- Compatible with Mono on Linux
