Hierarchical Bandwidth Limitation of Surround Sound—Part II: Optimization of Bandwidth Allocation Strategy
A technique for band limiting a multichannel surround sound, previously described, requires an optimization strategy based on subjective testing. In this technique, the 5 channels are transformed into a hierarchical domain where each transformed signal is assigned some percentage of the available bandwidth. Two cases with total bandwidth of 40 and 60 kHz were tested using a wide range of audio samples, and the resulting audio quality on a 100-point scale was rated at 87 and 93, respectively. This technique was superior to traditional bandwidth-limiting algorithms.
