Bayonne is the telephony server of the GNU project. It offers a script-driven threaded multi-line state event telephony service on GNU/Linux, xBSD, and Microsoft Windows for building voice response systems, and uses telephony plugins for runtime driver configuration. It also features "TGI" for making Perl applications "telephony aware". It may be used to build telephony-based system administration, home automation, automated attendant, v-commerce, and voice messaging systems.
Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording, and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. It supports a wide range of audio inputs, outputs, and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console-mode user interface is included in the package.
Webplay creates, from a collection of MP3s and Ogg Vorbis files (indexed from a directory or MySQL/PostgreSQL database), a Web-based jukebox with support for multiple independent streams. If Lame/oggenc are available, it can change the bitrate or codec of a file in real time to a selectable value. Each user controls their stream via a Web interface and can skip back, forward, or to a specific track; increment or decrement the bitrate; and check the current playlist, song, or bitrate. Playlists can be looped, randomized, played locally on the webserver, edited, deleted, reused, or renamed.
SlimServer provides an elegant and easy to use interface for playback of music stored in many audio formats, and supports Internet radio stations, playlist management, Web access, and an infrared remote control. The music remains on the host computer and streams over the network to any streaming audio client.
The TunePimp library is an audio file tagging library that uses MusicBrainz for track identification/lookup. It will attempt to automatically identify the files, and will present the user with possible matches for files that are not automatically identified. Once the files are identified, it writes new metadata tags to the music files and writes the files to a user-defined directory hierarchy. It supports WAV, MP3, Ogg Vorbis, and FLAC files.
Find Duplicate Music Files detects music files that contain the same music, even if the files are differently named, and are in different formats such as MP3, OGG, WAV, WMA, M4A, and RealAudio and contain different or non-existent meta-information such as ID3 tags. The program operates on whole directories of music files, analyzes them, and outputs the filenames of pairs that seem similar, based on their audio fingerprint or perceptual hash.
Naiocast is a Web based streaming server, similar to SHOUTcast and Icecast. It currently supports MP3 audio streams only. It can be used to create an Internet radio station or a privately running jukebox. It requires neither expensive dedicated servers nor compilation on the target machine. The project includes: Naiocast Server, which accepts a stream sent from a computer and sends it to listeners over standard HTTP; and naioSC, which sends the audio stream to a Naiocast server to broadcast to clients. It runs typically in the place where the audio is generated.
