GNU ccAudio2 is a stand-alone portable C++ class framework for manipulating
audio data. GNU ccAudio2 offers platform indipendent classes for directly
accessing audio files from disk. These classes are endian aware and also,
unlike some audio file manipulation libraries, content format aware;
ccAudio treats audio as an array of descreat sample points rather than simply
as binary data. ccAudio can also manipulate header information such as
annotations. GNU ccAudio2 supports sun audio, raw samples, and RIFF encoded
audio data. In addition to manipulating audio thru disk files, GNU ccAudio2
can provide audio processing of sample sets in memory. This includes generation
of pure tones, energy measurement of audio poackets, and software codec
conversions. GNU ccAudio2 includes a framework for developing plugin audio
codecs and is intended to be a carrier for freely licensed audio codecs as well
as to expand into a general purpose audio/signal processing C++ library.
The CELT codec is an experimental audio codec for use in low-delay
speech and audio communication. It's meant to close the gap between
Vorbis and Speex for applications where both high quality audio
and low delay are desired.
Ardour is a digital audio workstation. You can use it to record, edit, and
mix multi-track audio. Produce your own CD's. Mix video soundtracks.
Experiment with new ideas about music and sound. Generate sound
installations for 12 speaker gallery shows.
Ardour capabilities include: multichannel recording, non-linear, non-
destructive region based editing with unlimited undo/redo, full automation
support, a mixer whose capabilities rival high end hardware consoles, lots
of plugins to warp, shift, and shape your music, and controllable from
hardware control surfaces at the same time as it syncs to timecode. If you
have been looking for a tool similar to ProTools, Nuendo, Cubase SX, Digital
Performer, Samplitude, or Sequoia, you might have found it.
Audiere is a high-level audio API. It can play Ogg Vorbis, MP3,
FLAC, uncompressed WAV, AIFF, MOD, S3M, XM, and IT files. For audio
output, Audiere supports DirectSound or WinMM in Windows, OSS on
Linux and Cygwin, and SGI AL on IRIX.
Audiere is open source and licensed under the LGPL. This means that
you may freely use Audiere in commercial products, as long as you
do not modify the source code. If you do modify Audiere and release
a product that uses your modifications, you must release your changes
to the code under the LGPL as well.
Audiere is portable. It is tested on Windows, Linux-i386, Cygwin,
and IRIX with at least three major compilers. Most of Audiere is
endian-independent, so I expect it would work with few modifications
on other architectures.
Vorbis is a general purpose audio and music encoding format
contemporary to MPEG-4's AAC and TwinVQ, the next generation beyond
MPEG audio layer 3. Unlike the MPEG sponsored formats (and other
proprietary formats such as RealAudio G2 and Windows' flavor of the
month), the Vorbis CODEC specification belongs to the public domain.
All the technical details are published and documented, and any
software entity may make full use of the format without royalty or
patent concerns.
This package contains:
- libvorbis, a BSD-license software implementation of the Vorbis
specification by the Xiphophorus company.
- libvorbisfile, a BSD-license convenience library built on Vorbis
designed to simplify common uses.
- libvorbisenc, a BSD-license library that provides a simple,
programmatic encoding setup interface.
Musicbox is a simple one-file-at-a-time audio tag editor. It can edit
ID3, Vorbis and FLAC tags via the TagLib library.
AcoustID fingerprinter is a cross-platform GUI application that
uses Chromaprint to submit audio fingerprints from your music
collection to the AcoustID database. Only tagged audio files are
submitted. Files tagged by MusicBrainz applications such as Picard
or Jaikoz are preferred, but it will submit fingerprints for any
files that have tags such as track title, artist name, album name,
etc.
Speex is an Open Source/Free Software patent-free audio compression
format designed for speech.
libworkman is a library that provides hardware control for various
audio apps.
Speex is an Open Source/Free Software patent-free audio compression
format designed for speech.
