cdstatus checks for drive errors, outputs disc information (such as type and table of contents), and is capable of ripping full CDs, using configurable track ranges and retry counts. It handles cddb lookups and makes use of per-user .cdstatus configuration files. It usually produces identical output to cdparanoia with much faster execution. It features direct-to-lame MP3 encoding and Ogg Vorbis encoding, as well as twolame support.
jMax is a visual programming environment for building interactive real-time musical and multimedia applications by allowing the user to interactively design dataflow circuits. The basic data types that can go through are integers, symbols, lists, etc. It is an event-driven system and has been used for MIDI processing. A second part of the system (DSP) allows a continuous signal to flow through a circuit, which is most useful for PCM sound (ie. microphone, sound files, etc.). The system is extensible by using shared libraries, you may add data processor types, data types, GUI elements, device types, and more. Data processors may also be designed as circuits and reused.
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.
