LMS 7.9 and Sox inline EQ

Hi,

I am using a vortexbox OS, version 2.3 = Fedora 20, LMS 7.9 and squeezelite and would like some help on getting some inline EQ working.

I started off by finding info from someone upsampling using LMS and editing the /etc/squeezeboxserver/custom-convert.conf file.

I can get the upsample to work, verified by checking the squeezelite logs. I then added the equalizer commands, and I get audio but the audio is not getting EQ'd. I have verified this with an FFT.

Ideally I would like to EQ without upsampling, but just entering SOX equalizer with the EQ parameter gets white noise.

Current custom-convert.conf

flc flc * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -D -q -t wav - -t flac -e signed -C 0 -b 24 - gain -1 rate -v -I -b 98 88200 equalizer 58.0 7.05q -10
flc pcm * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -D -q -t wav - -t flac -e signed -C 0 -b 24 - gain -1 rate -v -I -b 98 88200 equalizer 58.0 7.05q -10
wav pcm * *
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -D -q -t wav - -t flac -e signed -C 0 -b 24 - gain -1 rate -v -I -b 98 88200 equalizer 58.0 7.05q -10

I currently have Inguz working and have EQ successfully using the 31 band EQ, but this is not as precise as I would like (centrre freq and q) and the EQ process is causing a 3 second delay in audio whilst cueing new tracks, this is OK but I am sure SOX would be more efficient.

Does anyone have any experience with inline SoX processing with LMS? Appreciate any help!

thanks

Rob.
