PPT-Introducing Audio Signal Processing & Audio Coding

Dr Michael Mason Senior Manger Sound Development Dolby Australia Pty Limited Overview Audio Signal Processing Applications Dolby Audio Signal Processing Basics Sampling What is an audio signal. Decimation or downsampling reduces the sampling rate whereas expansion or upsampling fol lowed by interpolation increases the sampling rate Some applications of multirate signal processing are Upsampling ie increasing the sampling frequency before D project Guitar Effects.
