AlsaPlayer for Linux is a new kind of player that effectively runs pulse-code modulation or .PCM files. The player uses multithreading pretty heavily and was written specifically for giving some good exercise to the new Advanced Linux Sound Architecture (ALSA) driver and the library system. If you look closely, you’ll observe that AlsaPlayer has some highly interesting features that can be found only in the UNIX-based or Linux-based players. The main goal of the people who created AlsaPlayer for Linux was to develop a completely pluggable framework that could playback every type of media file, with majority of focus on the PCM audio data.
Audio visualization usually relies on hand-crafted features, like intensity, timbre or pitch. These metrics are defined by humans and are biased towards our cultural representation of sound. In this project, we have trained a Neural Net to generate these features directly from spectrograms, in an unsupervised way. We thus get rid of this bias and hope the resulting visualizations can help us perceive music in different ways.
projectM is an open-source project that reimplements the esteemed Winamp Milkdrop by Geiss in a more modern, cross-platform reusable library. Its purpose in life is to read an audio input and to produce mesmerizing visuals, detecting tempo, and rendering advanced equations into a limitless array of user-contributed visualizations.

… some archives from this milkdrop contest thread on Winamp forum and put everything into a single archive. Some of the presets are nice and quite original, but most of them are variations. The ones that seemed nice to me I copied and added exclamation mark to their names. ~ hydrogenaud.io/index.php/topic,59388.msg914054.html#msg914054
