Encoding of audio signal using bandwidth expansion

Abstract

The invention relates to for code to the bandwidth and narrowband sound source signal (x), which is convenient with a public knowledge's method for comparing, a corresponding of sound signal of quality sensor is improved. By using a frequency spectrum (C),/decoding a evaluation device for measuring device (101) serial or concurrency operations of code of routine (102) with a sound source signal of sensing enhancing, wherein a frequency spectrum (C) a comparison a signal frame of the connecting the main coding of sound source signal represents sampling value of multiple large measuring frequency spectrum coefficient. The enhanced frequency spectrum of wire length of the telescopic is a realizing claim the sound quality improvement of sensing of the base.
