I have a single 20-minute CCTV recording where spoken words are hard to make out. My priority is dialogue clarity—background hum, traffic rumble, and any other noise that masks the voices all need to be pulled down so the conversation is intelligible without introducing artifacts. You will work from the original video file I supply and deliver the finished audio already synced back into the footage, so I can play the cleaned-up video straight away. If you prefer Adobe Audition, iZotope RX, DaVinci Resolve Fairlight, or similar restoration tools, that’s fine; the method is up to you as long as the result is crisp, balanced speech throughout. When you respond, briefly show the relevant experience you have with forensic or dialogue-focused audio repair—no lengthy proposal required, just proof you’ve done this kind of work before. Acceptance criteria • Voices are clearly understandable across the full 20 minutes. • No audible warbling, metallic ringing, or unnatural gating. • Final deliverable is the original video format with the cleaned audio track in place.

Hi, I’ve done forensic dialogue cleanup on CCTV and bodycam audio where traffic rumble and HVAC hum were burying speech. I use iZotope RX for spectral de-noise + voice de-reverb, then light EQ and compression in Adobe Audition to pull words forward without that warbly/metallic artifact. Method is surgical — I reduce noise 10-15dB in bands around voice, automate gain so whispers come up and shouts don’t clip, then remux the cleaned audio back into your original video format so it plays straight away with perfect sync.
