You could check the RESULTING COMMANDS section of C-3PO player settings
to see what the actual command looks like in your system, in mine, where
I have a reduction in the RIGHT channel, this is the resulting command
for flac:
Code:
--------------------
flc pcm * 00:e0:4c:68:ce:77
# F noArgs, R noArgs, I noArgs, D RESAMPLE=-r %d
[flac] -dcs --totally-silent $START$ $END$ -- $FILE$ | [sox] -q -t wav - -t
wav -b 24 --buffer 32768 --multi-threaded - gain -h remix -m 1v0.91 2 rate -v
-M -b 95 48000 dither -f improved-e-weighted
that becomes:
flc pcm * 00:e0:4c:68:ce:77
# D RESAMPLE=-r %d, I noArgs, R noArgs, F noArgs
[flac] -dcs --totally-silent $START$ $END$ -- $FILE$ | [sox] -q -t wav - -t
wav -b 24 --buffer 32768 --multi-threaded - gain -h remix -m 2v0.91 1 rate -v
-M -b 95 48000 dither -f improved-e-weighted
--------------------
As you could see, the only difference is -m, wher channels are inverted
(first is out Left, second is Right, 1 is input left, 2 input right,
v0.91 stand for volume 91% of the input channel).
Depending on other settings adding "remix -m" or, in general, gain/
volume alteration could result in SOX claiming back the headroom in
excess, resulting in a sound louder, gain -h (option automatic headroom)
is there to avoid clippings.
BTW, the SOX volume control is considered one of the best out there but
be sure dither is applied when needed.
