Abstract

Bandwidth limitation in lossy audio coding schemes significantly reduces the perceived quality. Blind high frequency bandwidth extension schemes have been proposed but they don’t provide sufficiently good quality in applications where they are needed most, in portable audio devices with severe complexity constraints. The following work describes a high quality blind bandwidth extension method proposing efficient initial audio bandwidth detection and regenerated spectral envelop shaping enhancements. Objective measurements on processed signals show significant quality improvements with very low complexity requirements which allows easy implementation on a wide variety of platforms.
