Remove Hiss, Hum and Room Echo

Background noise ruins otherwise good recordings. File Studio's noise reducer analyses your audio to build a noise profile, then subtracts that noise pattern from the entire recording. This effectively removes constant background sounds like air conditioning hum, microphone hiss, fan noise, and ambient room tone. The result is cleaner audio that sounds closer to studio-quality, making your recordings more professional for podcasts, videos, and presentations.

Normalize Audio Loudness

In addition to noise removal, File Studio can normalise your audio's loudness to a consistent level. This ensures that quiet sections are brought up and overly loud peaks are reduced, creating a balanced listening experience. Loudness normalisation is essential for podcast episodes, audiobook chapters, and any content where consistent volume improves the listener's experience.
