A novel psychoacoustically motivated audio enhancement algorithm preserving background noise characteristics

S Gustafsson, P Jax, P Vary - Proceedings of the 1998 IEEE …, 1998 - ieeexplore.ieee.org
In this paper we propose an algorithm for reduction of noise in audio signals. In contrast to
several previous approaches we do not try to achieve a complete removal of the noise, but …
