CAM - Cpu's Audio Mixer ================================= This is an audio mixer with an interface or command line support.

soundKonverter is a frontend to various audio converters. The key features are: - Audio conversion - Replay Gain calculation - CD ripping

Rubber Band Library is a high quality software library for audio time-stretching and pitch-shifting. It permits you to change the tempo and pitch of an audio stream or recording dynamically and independently of one another.

Fetch/manipulate from Ogg-Vorbis audio files.

LPAC is a codec (coder / decoder) for lossless compression of digital audio files. "Lossless" means that any compressed file can be decompressed in a way it will be bit-wise identical with the original. This is the main advantage of LPAC compared to lossy formats like MP3, WMA or RealAudio. On the other hand, lossy codecs can achieve higher compression ratios. For example, MP3 at 128 kbit/s achieves a (fixed) compression ratio of 11, whereas LPAC's compression ratios range from 1.5 to 4, strongly depending on the audio material. Typically they are around 2 for pop music and 2.5 for classical music. This may not seem much, but remember you will get back every single bit, no matter how often you subsequently compress and decompress a file. It is true that general archivers (Zip, LZH, gzip) are lossless, too, but they often achieve nearly no compression on audio files.

Opus is a totally open, royalty-free, highly versatile audio codec. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec. Opus is designed to handle a wide range of interactive audio applications, including Voice over IP, videoconferencing, in-game chat, and even live, distributed music performances. It scales from low bitrate narrowband speech at 6 kbit/s to very high quality stereo music at 510 kbit/s. Opus uses both Linear Prediction (LP) and the Modified Discrete Cosine Transform (MDCT) to achieve good compression of both speech and music.

This is the home page for the Open Source Audio Library Project. This is a project designed to implement a world class set of classes in C++ that will handle all of the audio functions one would like. It is designed to be multi- platform with UNIX based platforms as the base. This project is still in the beta code phase and a beta version that will illustrate the power and flexibility is now available. This version supports the Linux (OSS) audio device, Solaris Sparc audio device, FreeBSD (OSS) audio device, wav, au, aiff, aifc, mp3, and numerous other formats. It is important to note that this is not an application but a C++ library that others can use to create an audio application or to easily add audio capabilities to an existing application.

FLAC is an Open Source lossless audio codec. FLAC is comprised of * libFLAC, a library which implements reference encoders and decoders for native FLAC and Ogg FLAC, and a metadata interface * libFLAC++, a C++ object wrapper library around libFLAC * flac, a command-line program for encoding and decoding files * metaflac, a command-line program for viewing and editing FLAC metadata * user and API documentation
