Reduce background noise from recordings. Works well on podcasts, interviews, and voice notes.
Eliminate unwanted background noise from voice recordings, interviews, and podcast episodes. Our Audio Noise Reducer uses spectral gating DSP to attenuate stationary background hiss, computer fans, air conditioners, and line hum without degrading human speech.
Contains 50Hz/60Hz electrical hum and microphone background hiss.
Silent pauses between words with clear, crisp vocal transients.
How to Use
Select audio files with background air conditioning hum, fan noise, or electrical hiss.
Adjust noise reduction intensity (20%–50%) to remove steady background noise while preserving natural vocal speech.
Export your studio-clean audio file ready for podcast publishing or video editing.
Clean Vocal Track Ready
Crystal-Clear Voice Speech
The noise reduction algorithm analyzes the frequency spectrum of your recording and applies an adaptive spectral gate. It attenuates steady background noises — such as computer fan noise, air conditioner hum, microphone hiss, and room rumble — while preserving human vocal frequencies.
Start with a moderate setting around 20% to 35%. Setting noise reduction too high (above 70%) can strip higher vocal harmonics and make speech sound slightly robotic or underwater. A moderate pass removes 80%+ of background noise while keeping speech crisp.
Spectral denoising is designed primarily for continuous stationary noise (fan hum, hiss, line buzz). For isolated loud interruptions, we recommend using the Audio Cutter to trim out pauses or the Equalizer to notch out specific offending frequencies.
