I just have sox handlng upsampling and peq system-wide to TRN Black Pearl in NOS mode:
sox -t waveaudio "Stereo Mix" -t waveaudio 1 rate -v 11289600 sdm -f clans-6 -t 16 -n 16 %equalizer%
where %equalizer% is set by a script that line-by-lines a profile into equivalent sox filters. Really there's no reason to paypig higher than $5
