Please ignore my previous post - I misread 'FIR' where you wrote 'IIR',
and that explains it all...

Fons sent me a LADSPA and native jack filter that he wrote that will
do this. I haven't tested it yet. When I finally get jack up and
running on my system I'l

Looks like exactly what I need. The option stuff seems fairly
intuitive so far. It has the -efl option which is a low pass filter
built in but there isn't a gain setting. So I'm not quite sure

Filter 1: F = 50 Hz, A = 9
Filter 2: F = 2120 Hz, A = 1

What's your take on the pink noise calibration? I'm not sure yet if
I'm going to go to that much trouble but if I did how easy is it to
convert that to a LADSPA filter?

Fidelity is in fact the primary goal.

Sweet. What input did you use on your soundcard? Can I yak with you
off list? This is getting kinda

Not sure if it's scriptable, but I believe Audacity has this built in:
Effects -> Equalization -> RIAA

Do you know if the RIAA_EQ in JAM includes this?

some google research.
According to http://www.tracertek.com/newway.htm they claim the "new"
and best way to do LP to CD is to use a flat preamp, record at 24bit,
96kHz and then apply the RIAA curve in software after the fact.
