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: Outdoor Balcony Birds, Vehicles, and Surrounding Noise · audio · group: background-noise-removal

Input — what we sent

A real-world outdoor speech recording captured on a balcony with birds, traffic, and ambient environmental noise, used to test enhancement in a more variable and harder-to-clean audio setting.

Why this input is hard

· Suppression of dynamic outdoor noise
· Speech preservation in noisy environments
· Handling variable ambient sounds
· Reduction of birds and traffic noise
· Overall audio quality improvement

Output — unretouched

Adobe Podcast Enhance⚠ StruggledThe voice remained clear and understandable, but the tool noticeably altered the original vocal tone and natural characteristics.Audo Studio✓ WorkedKept the voice clear, natural, and understandable without noticeable robotic artifacts or voice distortion.Auphonic⚠ StruggledThe output significantly changed the original voice, making it sound more robotic, louder, and less natural.Cleanvoice⚠ StruggledSignificantly altered the speaker's tone and voice characteristics; the output sounded less natural and did not closely match the original recording.Noise Remover✓ WorkedPreserves the speaker's natural tone in the cleaned audio.
