What was measured

Handling different noise types

Does the tool perform equally well on steady noise like fan hum, intermittent noise like dog barking or door slamming, and overlapping speech?

decisive for this rankingtransformation

Real recordings contain different noise patterns, so performance across hum, barking, slams, and overlapping speech is part of the main task. (3 of 3 judges)

Indoor AC + Fan Background Noise

A real-world indoor speech recording with continuous background noise from both an air conditioner and a fan. It is designed to test whether tools can suppress overlapping mechanical noise while preserving speech naturalness.

Why this input is hard

· Removal of multiple overlapping indoor mechanical noises
· Speech enhancement and isolation
· Voice quality preservation under steady noise
· Minimal-artifact background noise suppression

Adobe Podcast Enhance◐ MixedIt handled continuous environmental noise well, but the report still called for more testing on crowd noise, keyboard clicks, music, and sudden transients, so broader noise-type coverage was not demonstrated.Audo Studio◐ MixedThe tool handles steady background hum reasonably well, but it is weaker on transient noises such as bumps, clicks, startup hiss, and other short-duration artifacts.Auphonic✓ WorkedThe tool handled multiple noise classes in one clip, including continuous mechanical noise, hiss, breathing noise, and short microphone disturbances.ElevenLabs Voice Isolator◐ MixedIt handled steady AC/fan hum well, but performed worse on short-duration noises, microphone interference, and sudden sound artifacts.
