| 20080300869 | Audio Signal Dereverberation - A method of estimating the reverberations in an acoustic signal (y) comprises the steps of determining the frequency spectrum (Y) of the signal (y), providing a first parameter (α) indicative of the decay of the reverberations part (r) of the signal over time, and providing a second parameter (β) indicative of the amplitude of the direct part (d) of the signal relative to the reverberations part (r). An estimated frequency spectrum ({hacek over (R)}) of the reverberations signal (r) is produced using the frequency spectrum (Y) of a previous frame, the first parameter (α), and the second parameter (β). The second parameter (β). The second parameter (β) is preferably inversely proportional to the early-to-late ratio of the signal (y). | 12-04-2008 |
