Digital audio compression allows the efficient stor-age and transmission of audio data. The various au-dio compression techniques offer different levels of complexity, compressed audio quality, and amount of data compression. This paper is a survey of techniques used to com-press digital audio signals. Its intent is to provide

requirements of digital audio files. All of our approaches replace the original audio signal by approximations that are made up by a linear combination of cosine functions. We describe basic ideas behind data compression methods used in mp3 players. The numerical ex-periments use several interesting MATLAB/Octave commands, including commands ...

14.5 Digital ltering The DCT algorithm can be used to not only interpolate data, but to compute a least-squares t to the data by omitting frequencies. The process of computing a least-squares t to digitized signals by omitting frequencies is called digital ltering. Digital ltering can reduce the storage requirements of digital audio by
