Abstract:
An electronic audio apparatus is described that uses a digital audio filter in which a splitter separates an input frame of discrete time audio into different time interval portions. Separate digital filter blocks then operate in parallel upon those time interval portions, respectively. A combiner merges the filtered portions into a single audio channel signal. Other embodiments are also described and claimed.
