My primary setup is a conventional cartridge with a robust archival preamp with multitudes of period-correct analog curves. Expert opinions needed.Ĭlick to expand.The inverse RIAA is for the 'alternative setup' with the displacement-sensitive cartridge with a mandatory RIAA preamp. Now that I think about it, maybe it would work if I told it to implement a gain of around -20 dB? I want to be sure to make as few gain changes as possible and have it be the exact same thing as if i transferred the record with no RIAA emphasis/deemphasis in the first place.

I know a pretty good deal about a lot of 78 RPM restoration but not so much about Nyquist. I've tried a bunch of things only to get errors or very mangled/destroyed waveforms. I'm pretty sure that the program is misleading at first glance to newbies like me because the 'zero frequency' is actually a pole around 50 kHz and not where you tell it that that frequency should have zero gain (?). I've been playing around with the Wayne Stegall program, but either it doesn't work the way I think it should or I've critically misinterpreted something. Any Nyquist mathematicians out there able to help me out in creating an inverse RIAA IIR command that can be plugged into Audacity's Nyquist prompt? The sampling frequency is 96 kHz, and it needs to have 1 kHz with 0 dB gain.
