Tool usage guide
The Audio Denoise Chain tool reduces noise in audio files using a multi-step process. It combines highpass and lowpass filters with FFT denoise, and optionally applies RNNoise for enhanced cleanup, delivering clearer audio output.
Background
A podcaster recorded an episode with a constant low-frequency hum from the microphone setup.
Problem
The hum distracts listeners and reduces audio professionalism.
How to use
Upload the audio file, set highpass frequency to 80 Hz to filter out the hum, and enable RNNoise for additional cleanup.
highpassFreq: 80, useRnnoise: trueOutcome
The hum is significantly reduced, resulting in a cleaner and more engaging podcast episode.
Background
A journalist recorded an interview in a noisy environment with traffic sounds in the background.
Problem
Background noise makes it difficult to hear the interviewee clearly.
How to use
Upload the interview audio, adjust lowpass frequency to 12000 Hz to cut high-frequency noise, and set noise floor to -25 dB.
lowpassFreq: 12000, noiseFloor: -25Outcome
The tool accepts various audio formats including MP3, WAV, AAC, M4A, OGG, Opus, and FLAC, as indicated by the audio/* file type.
RNNoise is an optional neural network-based noise reduction algorithm. Enable it for advanced cleanup of complex noise patterns in audio.
Yes, you can set the noise floor in dB and configure highpass and lowpass frequencies to control the reduction intensity.
The default output format is MP3, but you can choose from options like AAC, M4A, OGG, Opus, FLAC, or WAV.
Yes, the maximum file size is 200 MB (209715200 bytes).
Background noise is minimized, and the interview audio becomes clear and easy to understand.
