Currently I'm writing a little (Unix) program for making ABX double blind
tests.
Current functionality:
* Able to load WAV/AIFF and MP1/2/3 files via lame
* Files must be Stereo, 44.1 kHz, 16 bit, up to 3 minutes long
* No DC canceling to reduce fading noise between A, B and X
* No sample adjustment to detect sample shifts between A and B
* Listener can switch between A (listen to A), B (listen to B), X (listen
to the unknown) and M (switches between A or B and X for ever replay)
* Block repeat, listener can select a block which is repeated (instead of
the whole piece of music).
* voting control and evaluation.
a/A listen to A
b/B listen to B
x/X listen to the unknown channel
m/M listen to A or B and X
Q exit program
^A vote for X=A
^B vote for X=B
F1 block begin is start of file
F2 move block begin 0.1s <=
F3 block begin = current time
F4 move block begin 0.1s =>
F5 block end is end of file
F6 move block end 0.1s <=
F7 block end = current time
F8 move block end 0.1s =>
