I'm trying to find lightweight compiled audio programs that will work well on older computers or computers with limited resources. I'd like to add more music resource recommendations to the Schoolforge web site ( https://www.schoolforge.net/ ) and think it would be useful for students or schools working with older or second-hand computers. As a starting point, I'll list some of the programs I've run across or used that might meet the needs of students or users wanting to develop/create/edit music on older machines. I've tried to concentrate on command line, ncurses, SDL and FLTK based applications since many are lightweight enough to work well on older or low memory machines. If you have recommendations for other programs not listed, would appreciate very much if you would let me know. abcmidi - abc notation to midi and midi to abc conversion: http://abc.sourceforge.net/abcMIDI/ abcm2ps - abc notation to sheet music in PDF format: http://moinejf.free.fr/ TiMidity++ - midi/midi Karaoke player, converts midi to wave using soundfonts/gus patches: http://timidity.sourceforge.net/ Milkytracker - mod file creator/player: http://www.milkytracker.org/ sox - Sound eXchange: http://sox.sourceforge.net/ gramofile - record records and other input, has pop filter: http://www.opensourcepartners.nl/~costar/gramofile/ Wave utilities: http://billposer.org/Software/waveutils.html WaveProject: http://sourceforge.net/projects/waveproject/ Soundtouch library and program to change tempo, pitch and playback rates (library used by audacity): http://www.surina.net/soundtouch/ Xiph.org has several useful command line programs and libraries: https://www.xiph.org/downloads/ fast and light recorder, FLTK front end for sox: http://www.matteolucarelli.net/flrec/index_en.htm FLTK audio editor (I'm working on some patches to get it to compile with FLTK 1.3.2 and later compilers and possibly add some new features.): http://sourceforge.net/projects/apcstudio/ audio examples using SDL-widgets GUI library: http://members.chello.nl/w.boeke/SDL-widgets/ alsamixergui, FLTK front end to mixer: https://packages.debian.org/wheezy/alsamixergui umix, ncurses mixer for Unix and Linux systems: http://umix.sourceforge.net/
