Streamripper records MP3, Ogg, AAC, and NSV audio and video files from Shoutcast and Icecast compatible streams. The streams can be recorded as a whole or in individual tracks. Streamripper also features a relay stream, which lets you listen or watch live from multiple clients while recording.
GramoFile is intended primarily for transferring gramophone records to CDs, but has many other possible uses. It can record very long .wav files with a bargraph signal peak-level meter, playback any part of the files, split long .wav files into separate tracks (with automatic track location), and process the signal with filters to reduce ticks and pops (multiple filters are provided, they can be applied in any order (multiple instances) with user-adjustable parameters). Track splitting and signal processing are done in the same run, and don't need any temporary files.
Pip is a wrapper for programs that won't use stdin and stdout, but require filenames to be given on the command line; it lets you use '-' as a special filename. Now you can build pipelines to your heart's content. Pip takes care of creating and removing the temporary files needed. Also included is pip_latex, which handles the peculiarities of TeX and LaTeX.
