this is a simple level meter that displays on the plasmatrim
LED strip (http://www.plasmatrim.com/).
it is currently linux-only, due to the dependence on /dev/hidraw,
but could be easily ported with, say, signal11's hidapi. the JACk
dependency may be more difficult to tease out, but you could probably
shim in any callback-based audio API without too much trouble.
build with:
./waf configure
./waf
use with:
./analyzer /dev/hidraw{N}
it will create a JACK port into which audio can be routed.
feature wishlist:
* better windowing (i.e. not dependent on blocksize)
* spectrum analyzer (FFT or wavelet decomposition)
* EBU R 128 loudness metering
