A Simple, Efficient Algorithm for Reduction of Hiss Amplification Under High Dynamics Compression

Document Thumbnail

We present a very simple, effective, and computationally efficient algorithm to reduce the typical hiss amplification (or 'breathing') artifact of dynamics compressors working under high compression ratios. The algorithm works in the time domain, is very easy to implement, has a very low computational cost and requires little program memory, therefore being of special interest for consumer-audio applications.
