DIFFUSE SOUND ENVELOPE SHAPING FOR BINAURAL CUE CODING SCHEMES AND THE LIKE.

摘要

An input audio signal having an input temporal envelope is converted into an outputaudio signal having an output temporal envelope. The input temporal envelopeof the input audio signal is characterized. The input audio signal is processedto generate a processed audio signal, wherein the processing de-correlatesthe input audio signal. The processed audio signal is adjusted based on the characterizedinput temporal envelope to generate the output audio signal, wherein the outputtemporal envelope substantially matches the input temporal envelope.
