Clean up noisy audio recordings by applying a High-pass filter (rumble removal), Low-pass filter (hiss removal), and Dynamics Compressor. Signal analysis shows you the noise profile before processing.
Key Features
Signal analysis
RMS level, peak level, and high-frequency content ratio help diagnose the noise profile.
High-pass filter
Remove low-frequency rumble and hum below a configurable cutoff (20–500 Hz).
Low-pass filter
Cut high-frequency hiss above a configurable cutoff (1 kHz–20 kHz).
Dynamics compression
A compressor reduces the dynamic range, making quiet noise less audible.
How to Use
- 1Upload a noisy audio file.
- 2Review the signal analysis to understand the noise profile.
- 3Adjust the High-pass and Low-pass cutoff frequencies.
- 4Set compressor threshold and ratio, then export the cleaned audio.
