A separate equalizer, or perhaps just a preset within
one of the existing parametric equalizers, to apply the
RIAA playback curve. I have a Terratec DMX6Fire audio
interface with direct phono inputs and the audio
delivered by this input is uncorrected. Would save
needing an external amplifier just to fix the curve.
(For my big digitzation of old LP library project)
Being able to apply this equalization in real-time
during recording would be even better since it would
save a pass.
