hello Richard, hello Ecasounders!

i'm using ecasound version 2.4.4 on mac os x for automated offline
tuning - i.e. *not* realtime. therefore i've been trying to use your
computer music toolkit (cmt) v1.15 [1]. i would like to implement its
rms compressor with the following settings:

COMP_THRESHOLD= (RMS value of input.wav) - 10 dB # ???
COMP_RATIO=0.125    # 8:1
COMP_ATTACK=0.005   # 5ms
COMP_DECAY=0.05     # 50ms
ecasound -i $INPUT_FILE -eli:1073,$COMP_THRESHOLD,$COMP_RATIO, 
what's the proper setting for COMP_THRESHOLD if this threshold should  
be 10 dB under the RMS value? can i run this compressor in one step  
or do i have to get the RMS value first?
thanks - denis
