Enhance Voices in Recordings

I have two interview-style recordings that need serious cleanup. The first runs a little over an hour and was captured on a phone; the second is roughly 30 minutes from a handheld recorder. Right now the background noise overwhelms everything, so the voices are buried.

What I need from you: reduce that noise until the speech is clearly readable, while keeping the voices natural—no robotic artifacts, no odd pitch shifts, and no missing words. A faint room tone is fine, but anything louder than a light hum has to go. When you’re finished, I should be able to follow every sentence at normal volume without straining.

Deliverables
• Two enhanced audio files in MP3 format, same running times as the originals.

Feel free to work in iZotope RX, Adobe Audition, Audacity, or any tool you trust, as long as the result meets the clarity requirement above. If you’d like a short sample to test your chain before committing to the full files, just let me know and I’ll send one over.
