The CMU Midi Toolkit (CMT) is a collection of software for writing interactive MIDI software in C. It includes a number of handy utilities along with an application "shell" that provides timing, scheduling, and MIDI interfaces that are portable across DOS, Mac, SGI, and Amiga platforms.
SBAM (Software Based Abled Mixer) is a new approach to computer-based DJing.. This project aims to help DJs concentrate on the important aspects of DJing and to decrease the stress factor. It is intended for the DJs that have no need for beatmixing or other advanced mixing techniques, which means you'll be limited when it comes to creative individual mixing of tracks. Instead, you'll be able to concentrate on finding the right track for the audience.
MPEG Maaate (MPEG audio analysis toolkit) is a C++ toolkit to parse and analyse audio data in the frequency domain, e.g. analysing MPEG-1/2 Layers 1-3 audio files in the compressed domain. It makes the encoded fields of an MPEG audio stream accessible and provides some content analysis functions like silence detection.
Aglaophone is a system of interconnectable modules for the recording, processing, and playback of real-time audio. It features a real-time spectrogram display for visualization along with a number of processing modules. Modules include filters, downsamplers, upsamplers, and quantizers. An MP3 comparison module allows interactive blind comparison of MP3 encoded audio with CD audio, demonstrations of spectral imaging, quantization, and Smith-Barnwell filter bank based wavelet decomposition are included, and there is a module that can perform an automatic spectral analysis of a speaker system.
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.
