What was measured

Voice preservation

After cleanup, whether the voice still sounds natural rather than hollow, robotic, underwater, or artifacted.

decisive for this rankingtransformation

A noise cleaner must reduce noise without damaging the voice; if the result sounds hollow or robotic, it fails the main use case. (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

Handling different noise types◐ MixedWorked reasonably well on steady AC hum, but was less effective on short-duration noises, subtle artifacts, and intermittent background sounds.Noise removal effectiveness◐ 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.

measured on Voice preservation

Adobe Podcast Enhance⚠ StruggledThe tool noticeably changed the original voice tone and character; speech stayed understandable, but the natural voice quality was not preserved well.Auphonic⚠ StruggledThe output voice became louder and slightly robotic, which reduced the speaker's natural voice characteristics.Cleanvoice⚠ StruggledPreserved intelligibility, but the output voice sounded artificial and somewhat robotic compared with the original recording.ElevenLabs Voice Isolator✓ WorkedThe speaker's voice remained natural and clear after processing, with no significant distortion, robotic artifacts, or unnatural changes.Noise Remover◐ MixedLeaves the voice generally natural, but automatically lowers speech volume around 0:20 and 0:24-0:25, introducing a voice-level artifact.
