Tool usage guide
The Audio Noise Reducer is a professional-grade utility designed to clean up your audio files by removing unwanted background noise, hiss, and hum using advanced filtering algorithms.
Background
A recorded interview contains a persistent low-frequency hum from an air conditioner.
Problem
The background hum distracts from the speaker's voice.
How to use
Upload the interview file, select the 'High-Pass Filter' algorithm, and set the frequency to 80 Hz.
algorithm: highpass, highpassFreq: 80Outcome
The low-frequency hum is removed, leaving the voice recording clear and professional.
Background
A lecture recording has significant high-frequency static due to poor microphone quality.
Problem
The static makes it difficult to transcribe the lecture notes.
How to use
Upload the recording, choose the 'FFT Denoiser' algorithm, and set the reduction level to 0.7.
algorithm: afftdn, noiseReductionLevel: 0.7The tool supports MP3, WAV, FLAC, AAC, OGG, and M4A formats.
The FFT Denoiser is recommended for most general noise reduction tasks.
Yes, you can use the Low-Pass Filter to reduce high-frequency hiss or interference.
Yes, higher noise reduction levels may remove some audio details, so it is best to adjust the slider incrementally.
Yes, the maximum file size for processing is 10 MB.
Outcome
The static is significantly reduced, making the lecture audio much easier to understand.
