Noise reduction uses audio filters to remove unwanted background sounds. Our tool applies two types of filters: a high-pass filter removes low-frequency noise (like hums and rumbles), while a low-pass filter removes high-frequency noise (like hissing and static).
These filters work by allowing certain frequencies to pass through while blocking others. A high-pass filter at 80 Hz removes deep rumble while preserving speech. A low-pass filter at 16000 Hz removes hiss while preserving most audio content.
Noise reduction removes unwanted background sounds from audio recordings using filters that target specific frequency ranges.
Yes, aggressive filtering can remove some desired audio content. Start with gentle settings and adjust gradually.
A high-pass filter allows frequencies above a cutoff point to pass through while reducing lower frequencies. It's great for removing hum, rumble, and wind noise.
A low-pass filter allows frequencies below a cutoff point to pass through while reducing higher frequencies. It's useful for removing hiss and static.
