You need to create a text file (you can use Notepad etc.) containing the
something like the following (this will become "custom-convert.conf" on
the server):
Code:
--------------------
flc flc * *
[sox] -q --multi-threaded --no-clobber -t flac $FILE$ -t flac -
equalizer 99.6 2.70q +3.6 equalizer 283 1.00q -2.9 equalizer 2293 1.00q +1.4
--------------------
Each entry for "equaliser" can hold one filter from REW. The first value
is the Hz, the second number is the quantisation (Q) and the third is
the gain (positive or negative). This one has three filters, it applies
only to flac files. You would need additional blocks for different
formats.
In REW, using a generic equaliser will give you a filters file like
below (this is not the one to match the convert above, don't get
confused :) ). You can see it has the Hz, gain and Q. So all you need to
do is pick those out and write them into the "custom-convert.conf"
format.
Code:
--------------------

Filter 19: ON PK Fc 950 Hz Gain -2.2 dB Q 5.000
Filter 20: ON PK Fc 1192 Hz Gain -5.8 dB Q 5.000
--------------------
Once you have your text file ready with the filter values, head to the
piCorePlayer web interface, click the "LMS" tab and upload your file
using this input:
35737
Select the file, then hit upload and it will whirr away for a bit and
restart LMS, and you'll have your filters applied. If you want to undo
them, simply upload a blank document.
