Title:
A zone alternative quantization method and a device of an audio signal
Document Type and Number:
Japanese Patent JP6042900
Kind Code:
B2
Abstract:
The present invention relates to a method and device for quantizing voice signals in a band-selective manner. A Voice decoding method may include inversely quantizing voice parameter information produced from a selectively quantized voice band and performing inverse transform on the basis of the inversely quantized voice parameter information. Thus, according to the present invention, coding/decoding efficiency in voice coding/decoding may be increased by selectively coding/decoding important information.
