[linux-audio-user] [OT] recording fom turntable (ripping LPs)

[Jan Depner]

I just had a similar problem.  I was getting hum from my receiver/amp so
I connected the turntable outputs directly to a mic preamp (to get
enough gain to record).  The problem is that records are/were recorded
using what is known as the RIAA EQ.  You can find the technical reasons
on the web.  Basically it boosts the treble and cuts the bass.  All
phono preamps are supposed to reverse this curve so if you're not using
a phono preamp you get a very tinny sound.  What I did was to put the
reproducing RIAA EQ curve into JAMin (setting compression ratios to 1),
run the inputs through JAMin, and then record using Ardour.  I could
have put the EQ into Ardour but it's nice to hear it before you record
it.  The RIAA EQ .jam file is now in the jamin/examples directory when
you get JAMin from CVS.  Just put it into ~/.jamin and load it when you
start JAMin.
