Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail. Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters. The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.
Lava's jWave is a versatile set of packages for Java that allow you to easily create and process RIFF files, with a special emphasis on reading and writing Microsoft PCM .wav files. jWave was initially released as an integrated feature of Lava, a general-purpose class library for Java. By popular demand, it is distributed in its own bundle.
mp3dup looks for duplicate files in recursively searched directories. It is written to check for duplicate MP3 files, but can be used to find duplicate files of any type. It can told to find files that have completely identical contents, to find files that start or end with identical data, or to find files with the same ID3-tag.
The MusicBrainz client library (also known as mb_client or libmusicbrainz) is a library for developers that wish to add MusicBrainz metadata lookup capabilities to their applications. It calculates CD Index IDs and Relatable's acoustic fingerprints, and looks up the metadata associated with the calculated IDs.
Open Sound World (OSW) is a scalable, extensible programming environment that allows musicians, sound designers, and researchers to process sound in response to expressive real-time control. It combines a familiar visual patching paradigm with solid programming language features such as a strong type system and hierarchical name spaces. OSW also includes an intuitive model for specifying new components using a graphical interface and high-level C++ expressions, making it easy to develop and share new music and signal processing algorithms.
