Nice to find someone who understands audio interfaces, and no I'm not an extremist vinyl fondler. I control the volume on the pre-amp, manually, then it goes to my industrial Brazilian "Watsom" amp, low-end compared to the racked models Sepultura use at concerts, but powerful enough to send cops over every now and then. A led wouldn't be of much use, one of the stations, Ibiza Sonica (mellow compared to actual clubs), frequently broadcasts from live venues, drops in & out and has gain hickups like somebody sat on an upslider. When the other station stops, Couleur 3, it's usually because my crappy ISP connection did. I only listen to those two cause I can't figure out Santa Monica KCRW's new grid. >If you have a nice usb midi controller with knobs and leds, and if >you are not scared by writing code, you could write a small program >to run & kill mpg321/mplayer/whatever instances depending of >current state of the controller. It's not complicated afaics. Nah the stressful part was using my MIDIbots router whose Lua scripts I idiotically tweaked just before the event. At home who cares, it can crash & burn. >Using directly libmad/libcurl rather than a player and submitting >audio data to the device could allow switching between stations to >be smoother. Example, start decoding the next station while the >previous is still playing, etc. I'm more concerned about overloading the Geode than rude crossfades. That setup is just for radio, my offline library is a hell lot hairier to manage and definitely requires a rich UI. Thx for the advice on libmad/libcurl, I'll try that. -- p
