I have about two hours of voice tracks that I cannot rerecord, and have to improve as best as possible. It was recorded in a room with bare walls, and sounds quite tinny to me, high pitched and metallic. I’m hoping the pitch can be lowered, and otherwise made to sound much fuller. I’d be very grateful for any expert recommendations for the attachment.
Your recording isn’t terrible…
Experiment with Graphic Equalization. As you may know, low frequencies are on the left and high frequencies on the right.
Use the Preview, and after applying the effect you can un-do if you aren’t happy with the results.
Save your original file “just in case”… Don’t over-write it.
With EQ, it’s usually better to cut than boost. If you do boost, you can end-up boosting into clipping (distortion) and you can avoid clipping if you run the Amplify or Normalize effect before exporting. Normalizing “never hurts” in any case.
AI services like Adobe enhance (currently freemium) remove the worst offenders, (noise, reverb)
But IMO the AI output benefits from finessing, like EQ, de-essing, and de-clicking …
