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

Input file 1 — as supplied

0:00 / 0:00

Loading audio...

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

Handling different noise types⚠ StruggledReduces steady AC/hiss well, but struggles when speech and noise overlap closely; residual noise and a volume-dip artifact remain.Noise removal effectiveness◐ MixedRemoves AC and hiss-type noise from the clip, but background noise is still audible around 0:07-0:08 after cleanup.

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.Audo Studio✓ WorkedKept the speaker's voice natural and clear without robotic, metallic, or overly processed artifacts.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.
