Just a little experiment for how to synchronize visualization of additional data streams with the the playback of WebAudio music: The music samples are generated on the fly using a ScriptProcessor emulating some legacy AtariST. In addition to the stereo output the respective ScriptProcessor also generates three streams containing “playback volume” for the AtariST’s internal soundchip voices:
just for fun a more psychedelic WebGL based rendering of the same data (the WebGL here combines an orbit trap fractal with an inverse distortion, and the “music volume” is used to parameterize the rendering):
To complete the set of chipmusic emulators, here my WebAudio version of SC68 – an AtariST music emulator (that plays files like *.sc68 or *.sndh).
Eventough I had done some programming on the MegaST 4 back in the 90ies, I have to admit that at the time I had not realized that the machine had anything resembling a sound chip. Those were the days of 68k assembler, DSP machine code and GFA-Basic.. and we were just doing a Paintbox software for the “CHILI” framegrabber and realtime video-effects extension card… 🙂
But it seems the ST not only did have a MIDI interface but also a built-in sound chip…
