What was measured

Noise removal effectiveness

How much of the unwanted noise is actually removed, including whether it handles more than simple hiss.

decisive for this rankingtransformation

This directly measures whether the tool actually removes unwanted noise, which is the core job readers are hiring it for. (3 of 3 judges)

What was given, what came back

Test input: Indoor Air Conditioner Noise · audio · group: background-noise-removal

Input — what we sent

A real-world indoor speech recording with a single continuous air conditioner noise source, used to test predictable HVAC noise reduction while preserving natural vocal quality.

Why this input is hard

· Removal of continuous HVAC noise
· Speech preservation
· Consistent background-noise suppression
· Natural voice quality retention
· No manual enhancement

Output — unretouched

Adobe Podcast Enhance✓ WorkedRemoved most of the AC background noise and breathing noise, leaving the cleaned audio significantly quieter than the original.Audo Studio◐ MixedReduced a portion of the continuous AC hum and some air/breathing noise, but cleanup stayed partial because noise was still audible around 0.7–0.8 seconds.Auphonic◐ MixedReduced low-level background noise such as AC noise and some breathing sounds, but some background noise around 0.7–0.8 seconds remained audible.Cleanvoice✓ WorkedRemoved constant AC noise and most breathing noise, producing output that sounded significantly cleaner than the input.Noise Remover◐ MixedRemoves AC and hiss-type noise from the clip, but background noise is still audible around 0:07-0:08 after cleanup.
