Paloma is a program to manage an SQL database of digital music files, and facilitate their retrieval and playback in interesting ways. It works with music files of any form -- MP3, Ogg Vorbis, MIDI... whatever you've got a player for. Paloma makes it easy to rip your entire CD collection and store it on your hard disk (or a collection of CD-Rs) for instant random access; playlists can then be generated using arbitrary SQL commands.
Mp3blaster is an interactive text-based program that plays several audio file types (MP3, Ogg Vorbis, wav, and sid). It is one of the few audio players for the text console that allows full interactive control during playback. One of its key features is the ability to compose a very flexible playlist (while playing!). It plays most MP3 formats and has full mixer support built in.
The GlobeCom Jukebox is a music jukebox with integrated CDDB-aware ripping and groupware functionality. It is completely configurable from the Web interface, seamlessly integrates ripping from CD to encoded MP3, and supports grouping of songs, peak adjustment, account management for access, streaming of jukebox or single song, themability, album handling, and online help.
libsndfile is a C library for reading and writing sound files such as AIFF, AU, WAV, and others through one standard interface. It can currently read/write 8, 16, 24 and 32-bit PCM files as well as 32 and 64-bit floating point WAV files and a number of compressed formats. It compiles and runs on *nix, MacOS, and Win32.
Mp3Make is a program that automates the ripping and encoding of CD audio to mp3 files. Since the programs commonly used in linux to do this are seperate, it made sense to make a glue program to make life easier. This is supplemented by downloading a cd track list from a cddb server, and using that to name the files being created.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
bttvgrab is a program for grabbing video sequences using a bt848-based frame grabber card (e.g. Hauppauge WinTV, Miro PCTV...). The goal of bttvgrab is to provide high-quality grabbing suitable for video recording. Currently, this is accomplished by trying hard not to leave out a single frame, and to catch temproary delays by buffering several frames. In the future, synchronized sound will be part of it. Then you can create mpeg movies using mpeg2enc, the output files will be prepared for that, so that the conversion can be done by a simple shell script.
SoX is the Swiss Army knife of sound processing tools: it can convert sound files between many different file formats and audio devices, and can apply many sound effects and transformations, as well as doing basic analysis and providing input to more capable analysis and plotting tools.
