An Improvement in Sound Quality of LFE by Flattening Group Delay

Document Thumbnail

In this paper, we raise the issue of bass reproduction of surround music, when using LFE. We showed that this issue originates from the method of creating an LFE. Therefore, we propose the practicable method of ``LFE phase sync,'' that improves the quality of bass by applying the proper amount of delay. The optimum delay is calculated for using this method for various cutoffs and order of filters. We introduce the manner in which this method can be used for actual recording projects, and mentioned the method for monitoring when some encoder is used.
