Efficient transform coding of two-channel audio signals by means of complex-valued stereo prediction
12 years 9 months ago
Traditional MDCT-based perceptual audio coding schemes employ mid/side and intensity stereo techniques to allow efficient joint coding of the two channels of a stereophonic signal...
