Clean WhatsApp Call Audio

I have a single WhatsApp video call with my four-year-old daughter that runs just under a quarter of an hour. The conversation is precious, but the background hiss and general room noise make it tough to hear her little voice.

All I need is a cleaned-up version where her speech is clear and natural while the unwanted noise is removed or greatly reduced. Please keep the picture untouched; this is strictly an audio clean-up task.

Deliverables
• Final video file with the improved audio in the same resolution/format as the original
• Separate WAV or MP3 of the restored track (optional but appreciated)

Acceptance Criteria
• Daughter’s voice intelligible throughout, with no harsh gating or robotic artifacts
• Lip-sync preserved
• Overall volume balanced so normal listening levels work without strain

If you normally work in iZotope RX, Adobe Audition, Audacity, DaVinci Resolve Fairlight or a similar toolset, that’s perfect—just let me know what you plan to use. I can upload the original file as soon as we start, and I’d appreciate a quick turnaround if possible.
