Opus ~ Interactive Audio Codec


Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC and HE-AAC.

ALAC ~ Apple Lossless Audio Codec


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


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 ~ Analog Modelling Synthesizer


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
