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.

decisive for this rankingtransformation

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

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

Handling different noise types◐ MixedReduces steady AC and hiss well, but struggles when noise and speech overlap closely, leaving residual background sound and a volume-dip artifact.Voice preservation◐ MixedThe speech generally stays natural, but the tool introduces two volume dips around 0:20 and 0:24-0:25, which harms voice consistency.

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.ElevenLabs Voice Isolator◐ MixedThe tool reduced AC and breathing noise, but a noticeable transient noise at about 0.7–0.8 seconds remained audible.
