pyscmpd is a music player daemon designed for use on Raspberry Pis. It implements a subset of the MPD protocol, but instead of serving local MP3 files, it connects to SoundCloud.com and serves the streams found there. It supports a huge number of front-end clients through MPD, including ncmpcpp and Sonata. It allows you to configure which parts of SoundCloud are made available for browsing by defining categories and adding groups or users to them.
The Cainteoir Engine is a library for reading and recording different document formats (ePub, HTML, MHT, RTF, email, and others) to various audio output formats (such as PulseAudio, WAV, and Ogg/Vorbis). It also provides the following command-line tools: cainteoir, a front-end to the Cainteoir text-to-speech library; metadata, which extracts metadata from documents to RDF tuples; and tagcloud, which generates tag clouds and tag cloud data.
Khronosphere is an audio recording tool. Its special feature is a buffer that keeps capturing audio even before the actual recording is started. This enables the user to prospectively catch any interesting sound that normally would have been lost. The buffer size is freely definable by the user. The software itself places no restrictions; the only limits are the resources of the host system. Khronosphere is very similar to and inspired by Jack Time Machine. They both have the same basic concept, but Khronosphere supports larger buffer sizes.

It supports ID3v2, APEv2, FLAC, and Vorbis tags; multiple playlists; and tabs. It can copy, move, remove, and rename files.

Newpods can help you sync recently downloaded podcasts to your portable device. It will look through a directory tree to find podcasts that have been downloaded since the last time the program was run. It will then insert two commands into the bash history list: one to pushd to the podcast directory on your portable device, so you can clean out old files as needed, and one to copy the new podcasts to your portable device. If you're tired of copying files by hand, but don't want to use a heavyweight GUI solution, newpods might be right for you.
