Hi all,
I'm looking to record some albums into Ardour. I have a hardware
phono preamp that does the secret-squirrel RIAA eq stuff, but it's
very flaky. Is there a simple insert-it-and-forget-it eq for record
players?

The only real solution is a hardware preamp. You can apply
the RIAA filter in software, but unless you start with a
*very* clean digital signal it's not a good idea to do so.
Neither a mic input, a line input or a high-Z instrument input
has the right combination of impedance and sensitivity for a
phono cartridge. Not using the right impedance will mean the
EQ will be wrong.
I do have an RIAA ladpsa plugin, let me known if you want it.
*If* you want to try without a real phono preamp the only
input type that *could* work is a high-Z instrument input,
with a 47k resistor in parallel. But the noise level could
be below par.
Ciao,

Josh, if you decide to go the hardware route as Fons suggests, and
you're not afraid of a soldering iron, ESP Sound have what by all
accounts is an excellent phono preamp for moving-magnet pickups.

i'm not aware of one. if you have an alternative preamp that matches the
impedance of a phono cartridge, try building the curve yourself:
check out the FIL plugin. it's a four-band parametric. nedko arnaudov
has written a nice graphical wrapper, google for lv2FIL.
then look up the curve (i think it's on wikipedia) and just reconstruct
it with the appropriate filter settings. here's another one:
http://www.euronet.nl/~mgw/background/riaa/uk_riaa_background_1.html
i could get something that roughly resembles the RIAA shape with just
two filters. it's not really correct, but it's a start.

I've done that with good results with audacity (equalization -> riaa), i
don't think there's a ladspa plugin on Ardour.
Hope this could help

I think there is/was a preset for jamin for this floating on the web or even
inside the jamin distribution-package...
Oh, I like the old GDR record-players which had the correcting pre-amp built-
in. Just connect them to any line connector and you are set.
Have fun,
Arnold
