Izotope RX is so inaccessible that I literally can't even get passed the installation screen because nothing reads! Accentize Reviver Pro installs but I can't find it anywhere on my computer, so I had to uninstall it. Basically, the two best tools for the job are completely inaccessible to the blind. i have heard of something called Reaper, which does have accessible plug-ins that work with NVDA (my screen reader) but I have no idea if any of it actually restores frequencies and such. I did, however, receive some general recommendations from Perplexity, and they seem very reasonable, so I will include them here. This is the quick version.

"Summary Table of Frequency Restoration Goals
Frequency Range
Importance
Effect of Restoration
50–200 Hz
Adds warmth and fullness
Restores body and resonance
200 Hz–1 kHz
Vocal clarity and timbre
Enhances natural voice and instrument tones
1–5 kHz
Presence and articulation
Improves vocal “edge” and attack on piano"

I also found this to be interesting.

"Practical Considerations
•
Restoration is a balancing act; too much boost in any range can introduce noise or unnaturality.
•
Analogue equalizers and cautious digital EQs are well suited to restore missing lows and midrange.
•
AI spectral recovery tools focus mainly on boosting upper frequencies and “filling in” missing detail but cannot authentically recreate absent low-end.
•
Listening carefully and comparing before-and-after versions remains the best guide.
Your focus on naturalness and historical authenticity aligns perfectly with this frequency approach: restoring warmth and clarity without over-processing the treble region is key."
