I expect those interested may have already figured it out by now, but as
promised here is my own custom-convert.conf file that implements
parametric EQ with SOX:
Code:
--------------------
flc flc * b8:27:eb:e0:f9:75
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -q --multi-threaded
--no-clobber -t wav - -t flac -C 0 - equalizer 54.3 2.831q -19.2 equalizer 71.1
3.982q +9.0 equalizer 75.2 7.677q -5.4 equalizer 89.3 11.271q -5.5 equalizer
148 13.429q -13.3 equalizer 202 5.0q -6.2 equalizer 225 5.0q +6.3
--------------------
There are 7 filters here, as calculated by REW. The MAC address is of
course to limit the filtering to apply only to the player in the room
that the filters are for.
NB. I only use FLAC in my library. If you need to process other formats,
you'll need extra entries for each codec. I decided that it was too much
bother to do that, so I transcoded the few non-FLAC files I had into
FLAC to sidestep the issue.
Having an example of a known working file might help, especially the
stuff in the #FT line and the way that FLAC is invoked. This is all to
do with making sure that seek operations while playing files work, and
the filtering continues to operate after a seek. It's explained in an
earlier thread here:
