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 AC + Fan Background Noise · audio · group: background-noise-removal
Input — what we sent

A real-world indoor speech recording with overlapping AC and fan noise, used to test how well AI can suppress multiple continuous mechanical noise sources while keeping speech natural and intelligible.

Why this input is hard
  • · Removal of overlapping indoor mechanical noise
  • · Speech enhancement and isolation
  • · Voice quality preservation
  • · Minimal artifact introduction
  • · Improvement with no manual cleanup
Output — unretouched
