This is interesting. I am currently running SOX filters in LMS, using a

I came to this thread via a discussion on another website. That
discussion was related to how to use HiFiBerry DAC+ DSP under PiCore;
specifically how to install the dsptoolkit onto PiCore (I'm still
working on that !). However, it seems to me that the SOX approach is a
much better approach than

Awesome :) Glad it all worked for you. I wish I had known about SoX
before I wasted £70 and who knows how many hours on that HiFiBerry DSP!
On the plus side though it did introduce me to REW which mak
OK, latest news on this.
I set up the appropriate equalizer settings in custom-convert.conf and
am happy to report that:
1. They work - the bass response is smoothed out as required. Not quite
perfect yet, but I can try a bit of fine tuning.
2. Re-encoding to FLAC works just fine. The peak CPU

OK, I gave that a go and it work

Thanks again.
Would it reduce any delay even further by not re-encoding to FLAC, and
just stream the output as
In case anyone was trying the above, I've now edited it as the command
for turning off one channel was wrong.
I've also done some more tweaking and found limiting the flac

Hi,
Most of your filters are attenuating the bass but filter 2
Filter 2: ON PK Fc71.1 Hz Gain 9.0 dB Q 3.982
is adding a lot of gain in between filter 1 and 3 which are attenuating
bass.
Filter 1: ON PK Fc54.3 Hz Gain -19.2 dB Q 2.831
Filter 2: ON PK Fc
Having set up DRC using a RPi with HiFiBerry DIGI2 Pro + DSP card, I
have an issue.
When setting it up (having used REW to calculate the required filters),
I was of course using source material with significant bass content to
audition the results, and pleased with the way it tamed the bass hump
