Title: Software/plugin to *undo* low cut on a recording
Post by: illconditioned on March 06, 2008, 01:53:29 PM

Due to "user error" I choose low cut (-6dB/octave, 250Hz) instead of mic pad that I was aiming for.  (This was on Beyerdynamic MC930 mics.)

Is there any software/plugin that can "undo" this effect?  Ie., produce a linearly iincreasing gain on the bass at a rate of 6dB/octave?  I'm running Wavelab (5.0), but all I see (Waves package or builtin Q equalizer) apply a bump or a shelf of some sort.  I'm looking for a "ramp" shape in the EQ.

Thanks for any help...

Hey richard,

I doubt you can effectively "undo" a low cut filter applied on a mic since the sound never made it to tape - but the builtin Audacity eq will do a sloping eq that you can shape with yer mouse.

Good luck!

Thanks.  Yeah, I know I'll be boosting the signal and introducing some more noise, but I'm aiming to get *close* the the freq response that was originally there.  I'll try the Audacity.

I'm not sure how you would go about doing it every other octave, but I'm willing to bet the EQ in Audacity will hurt more than help...  There are some pretty good plug-ins out there for maximizing bass in a recording (although they're not free.)  I can recommend PSP VintageWarmer (sounds a bit more polished) or Waves MaxxBass/RBass (can work wonders with restoring low-end.)  These plugins restore the bass through not only boosting the level, but raising the harmonics of the frequency you're boosting.  Most EQ's would leave your low-end sounding too boomy and lacking punch, whereas the above two plug-ins would get it back to where it used to be.
