Library of OpenCORE Framework implementation of Adaptive Multi Rate Narrowband and Wideband speech codec.

The Audio-Scrobbler module provides a Perl and command-line interface to Last.fm's AudioScrobbler - http://www.audioscrobbler.com/.

The PyOgg project provides a set of python modules for the various streaming formats and protocols defined by the Xiph.Org Foundation. For now, it mostly deals with the Ogg bitstream container and the Vorbis audio codec.

A small and flexible console mixer using ncurses.

VisualOn AAC encoder library This library contains an encoder implementation of the Advanced Audio Coding (AAC) audio codec. The library is based on a codec implementation by VisualOn as part of the Stagefright framework from the Google Android project.

VisualOn AMR-WB encoder library This library contains an encoder implementation of the Adaptive Multi Rate Wideband (AMR-WB) audio codec. The library is based on a codec implementation by VisualOn as part of the Stagefright framework from the Google Android project.

WildMIDI is a simple software midi player which has a core softsynth library that can be used with other applications. The WildMIDI library uses Gravis Ultrasound patch files to convert MIDI files into audio which is them passed back to the calling application for further processing or output. The API of the library is designed so that it is easy to include WildMIDI into applications that wish to include MIDI file playback. With multiple MIDI file support you can develop applications to mix several midi files together at the same time and with the next release you will be able to use a different patch set for each MIDI file. The wildmidi player is a demonstration program to show the capabilities of libWildMidi.

XAnalyser is a program to analyse a stereo audio signal. It has two displays: Frequency Spectrum Using Fast Fourier Transform, the time domain of the signal is transformed into the frequency domain, i.e. the amplitude (in logarithmic scale) of the audio signal is plotted versus the frequency. Either the sum of the left and right channel of the audio signal can be shown or both channels simultaneously. XY Scope Roughly speaking, the audio signal of left channel deflects a point horizontally and the right channel vertically (just as the beam of a CRT would do). Thus, an audio signal only present on the left channel produces a horizontal line, whereas an audio signal only present on the right channel produces a vertical line. A mono signal produces a 45 degree line. A stereo signal creates a wilde pattern (if the phase is correct, predominately in the same direction as a mono signal) or may even fill the entire scope.

This is a Squeezebox Server plugin screensaver datetime replacement. Graphically displays current weather conditions and forecasts. Will also optionally display stock quotes and upcoming/active game information for MLB, NBA, NHL, NFL, and college football and basketball teams at user-configurable intervals.

The xsynth-dssi package contains the Xsynth-DSSI plugin, a classic-analog (VCOs-VCF-VCA) style software synthesizer with an editor GUI. Xsynth-DSSI was written by Sean Bolton, and was based on Steve Brooke's Xsynth code, but has since acquired polyphonic operation, band-limited oscillators, a better filter mode, and velocity-sensitive envelopes.
