Frequently Asked Questions
What types of noise can be removed?
High-frequency hiss (highpass filter), low-frequency hum (lowpass/notch filter), and broadband noise (combined filtering). Voice frequencies (300Hz-3kHz) are preserved.
Will noise removal affect voice quality?
Mild filtering has minimal impact on voice. Aggressive filtering can make voice sound muffled or tinny. Use the preview to find the best balance.
