What was measured

Noise removal effectiveness

How much of the unwanted noise is actually removed, and whether the tool handles different noise types or only simple hiss.

This is the core job: a tool only ranks well if it actually removes unwanted noise effectively. (3 of 3 judges)

Indoor Air Conditioner Noise

A real-world indoor speech recording with a single continuous HVAC/air-conditioner noise source. It is designed to test speech isolation and noise reduction when the background noise is predictable and steady.

Why this input is hard

· Removal of continuous HVAC noise
· Speech preservation with steady background noise
· Natural voice quality retention
· Background noise reduction with minimal cleanup

Output — unretouched

Also checked on this input — same tool, 2 other criteria

Handling different noise types◐ MixedIt performed reasonably on continuous AC hum and breathing, but struggled with short-duration or irregular noises that remained audible.Voice preservation✓ WorkedThe speaker's voice stayed natural and clear, with no significant distortion, robotic artifacts, or unnatural tone changes.

Adobe Podcast Enhance✓ WorkedThe tool removed most AC background noise and breathing noise, making the cleaned track significantly quieter than the original.Audo Studio◐ MixedThe tool reduces part of the continuous AC hum, but cleanup remains partial because residual noise is still audible after processing.Auphonic◐ MixedThe tool reduced low-level AC and breathing noise, but some background noise remained audible around 0.7–0.8 seconds, showing incomplete cleanup.Cleanvoice✓ WorkedRemoves steady HVAC noise well, taking out the constant AC hum and most breathing noise and making the output sound much cleaner and more professional.Noise Remover◐ MixedRemoves AC and hiss noise, but some background noise is still audible around 0:07-0:08 in the cleaned result.
