Abstract:
1. A method for reconstructing a decomposed audio signal, comprising: receiving, using a processor a plurality of frequency sub-band signals from a filter bank, the filter bank decomposing an audio signal into the plurality of frequency sub-band signals, the plurality of frequency sub-band signals comprising: grouping, using the processor, the plurality of frequency sub-band signals into two or more groups; delaying, using the processor, the two or more groups by a delay function, the delay function delaying by a different delay of a plurality of delays each frequency sub-band signal in each group of the two or more groups, such that each frequency sub-band signal in each group is aligned with the frequency sub-band signal having a greatest lag time in each group, the plurality of delays including a zero delay; and combining, using the processor, the groups to reconstruct the audio signal.
