Provides per-band compression with a fixed ratio and adjustable thresholds.
A spectral gate that only allows audio through if it hits a specific threshold at a specific frequency.
Allows for basic convolution-based processing. Key Feature: Subtract Mode (Noise Reduction) 🎙️
ReaFir is a go-to tool for removing steady-state background noise like computer fans, AC hums, or microphone hiss.
Excessive noise reduction in Subtract mode can lead to "metallic" or "tinny" artifacts.
If you tell me what you're using or the type of audio you need to clean up, I can give you more specific tips on setting the FFT size or threshold levels. Cockos ReaFIR - Review (Denoising)
