METHOD FOR SUPPRESSING THE LATE REVERBERATION OF AN AUDIO SIGNAL |
摘要 |
A method for suppressing the late reverberation of an audio signal. A plurality of prediction vectors are calculated. A plurality of observation vectors from the modulus of the complex time-frequency transform of an input signal is generated. A plurality of synthesis dictionaries from the plurality of observation vectors are constructed. A late reverberation spectrum from the plurality of synthesis dictionaries and the plurality of prediction vectors are estimated. A plurality of observation vectors are filtered to eliminate the late reverberation spectrum and obtain a dereverberated signal modulus. |
