What was measured

Voice preservation

After cleanup, does the voice still sound natural, or hollow, robotic, underwater, or artifacted?

Outdoor Balcony Birds, Vehicles, and Surrounding Noise

A real-world outdoor speech recording captured on a balcony with variable environmental noise such as birds and traffic. It is designed to test performance on more dynamic, unpredictable background sound.

Why this input is hard

· Suppression of variable outdoor environmental noise
· Speech preservation in changing acoustic conditions
· Reduction of birds and vehicle traffic sounds
· Overall enhancement of noisy field recordings

Output — unretouched
