[MP3 ENCODER] Simple ABX testing program

[Frank Klemm]

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 =>
    r/R         Review
    f/F         Forward/Cue
