Abstract
Many noise suppression systems are based on (short-term) spectral-domain filtering by using an analysis-synthesis filter-bank. This filtering technique causes a relatively high signal delay as a filter-bank for the analysis and synthesis part is needed. In this contribution, a filter structure with a significantly lower signal delay is presented. The proposed low delay filter achieves a higher amount of noise reduction than an analysis-synthesis filter-bank with the same signal delay.
