Reduced memory implementation technique of filterbank and block switching for real-time audio applications
摘要:
Presented herein is a reduced memory implementation technique of filterbank and block switching for real-time audio applications. Calculation of the pulse code modulated samples from the IMDCT samples and inverse window functions is simplified by exploiting the symetric qualities of the IMDCT function. As a result, memory requirements and operations are significantly reduced.
