Audio analysis

Praat (also the Dutch word for “talk”) is a free scientific computer software program for the analysis of speech in phonetics. It has been designed and continuously developed by Paul Boersma and David Weenink of the University of Amsterdam. It can run on a wide range of operating systems, including various Unix versions, Mac and Microsoft Windows (95, 98, NT4, ME, 2000, XP, Vista). The program also supports speech synthesis, including articulatory synthesis.

Wavesurfer is an audio editor widely used for studies of acoustic phonetics. It is a simple but fairly powerful program for interactive display of sound pressure waveforms, spectral sections, spectrograms, pitch tracks and transcriptions. It can read and write a number of transcription file formats used in industrial speech research including TIMIT.

Sonic Visualiser is an application for viewing and analysing the contents of music audio files.

Converters

MediaCoder is a free audio/video batch transcoder for Windows developed by Stanley Huang and licensed under the Mozilla Public License 1.1 (MPL 1.1) and Other/Proprietary License , which uses various open source audio and video codecs and tools to transcode different audio/video formats and has many extra features. Common uses for the program include compression, file type conversion and extraction of audio from video files. Many formats are supported, including MP3, Vorbis, AAC, Windows Media Audio, RealAudio, WAV, H.264, Xvid, DivX 4/5, MPEG-2, AVI, CD, and DVD.

MPlayer is a free and open source media player. The program is available for all major operating systems, including Linux and other Unix-like systems, Microsoft Windows and Mac OS X. Versions for OS/2, Syllable, AmigaOS and MorphOS are also available. The Windows versions works, with some minor problems, also in DOS using HX DOS Extender. A port for DOS using DJGPP is also available.[1] A version for the Wii Homebrew Channel has also emerged. [2]

MPlayer supports a wide variety of media formats[3]. In addition to its wide range of supported formats MPlayer can also save all streamed content to a file.

A companion program, MEncoder, can take an input stream or file and transcode it into several different output formats, optionally applying various transforms along the way.

MPlayer is a command line application which has different optional GUIs for each of its supported operating systems. Commonly used GUIs are gMplayer written in GTK+ (the default GUI for GNU/Linux and other Unix-like systems, and Microsoft Windows), MPlayer OS X (for Mac OS X), MPUI (for Windows) and WinMPLauncher (also for Windows). Several other GUI frontends are also available for each platform.

winLAME is a Windows front-end for LAME, a program which can transcode audio files between several formats.

BonkEnc is a CD audio extractor for Microsoft Windows.[1] Distributed under the terms of the GNU General Public License, BonkEnc is free software. The developers invite donations but they are optional.

Modular systems

SynFactory is an open source software synthesizer for Windows. It is based on the same sound generating principles such as subtractive synthesis as used in vintage modular synthesizers. Patches can be built from separate components and connected together with virtual patch cables. Due to the flexibility of the system, the range of sounds that can be created is huge.

The synthesizer is always ‘live’ and there is no separate edit mode. All changes and edits to the patch can be done while the patch is playing.

Generated sounds can be stored in .wav or mp3 format and be used as samples in other programs. For mp3 compression the open source LAME encoder is used.

aRts, which stands for analog Real time synthesizer, is an audio framework that is no longer under development. It is most famous for previously being used in KDE (series 2 and 3) to simulate an analog synthesizer.

A key component of aRts is the sound server which mixes several sound streams in realtime. The sound server, called artsd (d for daemon), is also utilized as the standard sound server for KDE2–3. However, the sound server is not dependent on KDE and can be used in other projects. It is a direct competitor to JACK Audio Connection Kit, another real-time sound server, and an indirect competitor to the Enlightened Sound Daemon (ESD). It is now common to use ALSA’s software mixing instead of artsd.

The aRts platform also includes aRts Builder — an application for building custom layouts and configurations for audio mixers, sequencers, synthesizers and other audio schema via a user-friendly graphical user interface. aRts is free software, distributed under the terms of the GNU General Public License.

Platforms

Ubuntu Studio is an officially recognized derivative[1] of the Ubuntu operating system, which is explicitly geared to general multimedia production. The original version, based on Ubuntu 7.04, was released on May 10, 2007.

dyne:bolic is a Live CD Linux distribution with a focus on multimedia production, and is distributed with a large assortment of applications for audio and video manipulation. dyne:bolic is based entirely on free software, and is recognized by the GNU Project for this characteristic.

AGNULA is a defunct project originally funded by the European Commission aimed at creating two Linux distributions for use in music and audio production: DeMuDi (the Debian multimedia distribution, based on Debian GNU/Linux) and ReHMuDi (the Red Hat multimedia distribution, based on Red Hat Linux). The project name stands for A GNU/Linux distribution for Audio’.

Musix GNU+Linux is a Live CD and Live DVD operating system for the x86 processor family based on Knoppix, Kanotix and Debian. It contains a collection of software for audio production, graphic design, video editing and general purpose applications. The initiator and co-director of the project is Marcos Germán Guglielmetti.

64 Studio is a free operating system based on Debian designed for creative users on x86-64 and legacy 32-bit hardware architectures. It intends to serve as an all-in-one solution for audio and video recording, editing, and other forms of media production.

Since 64 Studio is distributed with a free software license, anyone with a 64-bit computer can install it on their computer (in place of or alongside the well-known Windows operating system). An alternative installer is available for systems with 32-bit processors.

Streaming

Icecast is a free streaming media project maintained by the Xiph.org Foundation. It also refers specifically to the server program which is part of the project. Icecast was created in December 1998/January 1999 by Jack Moffitt and Barath Raghavan to provide an open source audio streaming server that anyone could modify, use, and tinker with.[1] Version 2 was started in 2001, a ground-up rewrite aimed at multi-format support (initially targeting Ogg Vorbis) and scalability.

PeerCast is an open source streaming media multicast tool. PeerCast uses peer to peer technology to minimize the necessary upload bandwidth for the original multicastor.

Firefly Media Server (formerly mt-daapd) is an open-source media server (or daemon) for the Roku SoundBridge and iTunes. It serves media files using Roku Server Protocol (RSP) and Digital Audio Access Protocol (DAAP).

VideoLAN is a project that develops software for playing video and other media formats. It originally developed two programs for media streaming—VideoLAN Client (VLC) and VideoLAN Server (VLS)—but most of the features of VLS have been incorporated in to VLC, with the result renamed VLC media player.
