ReaFIR

Cockos

ReaFIR is an FFT-based dynamics processor by Cockos that functions as a multi-purpose audio tool with five independent modes: EQ, Gate, Compressor, Convolve L/R, and Subtract. It enables frequency-specific processing with hundreds or thousands of bands and can be used as a linear-phase mastering EQ, surgical surgical EQ, multiband compressor, noise gate, or noise reduction tool. What makes it distinctive is its ability to apply per-band thresholds and ratios across a continuous frequency spectrum without traditional crossovers, plus optional linear-phase operation to eliminate artifacts.
