Honest Performance Boundaries
What works great (and what does not) on compressed Zoom files
Transparent expectations for remote call recordings:
Great for: Fan drones, AC hum, and hollow spare rooms
Strips continuous fan noise and wall reflections cleanly, making guest audio dramatically easier to transcribe or publish as a podcast.
Great for: Multi-speaker remote interviews
Handles alternating male and female voices recorded on AirPods, built-in laptop mics, or USB headsets.
Not for: Real-time live call suppression
CleanAudio cleans already-recorded files in post-production; it is not a virtual microphone plugin for live calls.
Boundary: Heavy packet-loss dropouts
Because we never hallucinate fake speech, words dropped entirely by poor Wi-Fi cannot be invented—only existing signal is purified.
Zoom Cleaner FAQ
Zoom Audio Cleanup FAQs
Confidential meetings, custom audition timestamps, and pricing.
Is it safe to upload confidential client or team Zoom recordings?
Yes. Transfers use TLS 1.3, stateless GPU inference runs in isolated Modal (us-east) container memory with zero disk retention, and Cloudflare R2 objects auto-delete after 24 hours—never used for AI training.
What if only the middle of my 45-minute call has loud echo?
After loading the file, drag the 30-second audition window slider straight to minute 20 and click 'Audition Window' to verify the cleanup on that exact spot free.
