Audio Data Management

Put the data you want to process inside /audio/input
Then change in utilvar.py under class:vs accordingly, with the name partition being underscore
e.g.

/GA2_SMUL/audio/input$ ls 
flt_G1.wav  saxof_G3.wav
  
class vs:
    instr = ["flt","saxof"]
    cor   = [ "y" , "m" ]
    mrk   = [ "v" , "1" ]
