AMIDI-Plug is a MIDI subsystem for XMMS, BMP, and Audacious. It processes MIDI files and sends their events to one of the available backends (currently ALSA, FluidSynth, dummy). With the ALSA backend, any hardware or software synthesizer, as long as it provides ALSA sequence ports, can be used to play MIDI with AMIDI-Plug. With the FluidSynth backend, AMIDI-Plug directly accesses the FluidSynth library for MIDI playback and sends the generated audio into effect and output plugins of the player. A dummy backend is also provided for testing and analysis purposes. Playback is fully functional: play, stop, seek, pause, song information are available.
ANDREW's Not a DVD Ripping and Encoding Wizard, but a command-line interface that simplifies the use of some programs to create AVI, Matroska, MP4, or OGM files from DVDs. ANDREW runs in interactive or batch mode; works on-the-fly or ripping DVDs to the hard drive; handles progressive, telecine, and interlaced NTSC and PAL formats; selects multiple audio and subtitle tracks by preferences or in full manual mode; splits movies into several files or encodes them by target size or video bit rate; and more.
ASCIIMathML is a script that converts calculator-style ASCII math notation (and many LaTeX formulas) to Presentation MathML while your Web page loads. It works with HTML and XHTML files in Mozilla/Firefox/Netscape 7+ browsers, as well as in Internet Explorer 6 with MathPlayer. For example, the solutions for the equation 'ax^2+bx+c=0' are expressed in the HTML file as '(-b +- sqrt(b^2 - 4ac))/(2a)', and display as nicely formatted MathML. The script can be easily used in wikiservers and blogs, as a rudimentary MathML editor (with instant preview), and to preview math formulas as they are typed into a Web page input area.
ASDF (A Simple DVD Frontend for MPlayer) is intended to make watching DVDs with MPlayer easier. It's written in Perl using the Qt toolkit. It provides an easy way to select the track you want to watch, as well as audio and subtitle languages and deinterlacing. It also provides a way to hide the short "empty" tracks that litter many DVDs.
