Digital Audio Compression - Columbia University
https://www.ee.columbia.edu/~dpwe/papers/Pan93-acomp.pdf
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-

A Tutorial on MPEG/Audio Compression
https://web.media.mit.edu/~tristan/Classes/MAS.945/Papers/Technical/pan96tutorial.pdf
audio compression. To contrast the complexity of the MPEG/audio algorithm with that of some simpler, generic audio compression algorithms, the annex of this paper presents the details of µ-law and the ADPCM algorithm adopted by the Interactive Multimedia Association. The MPEG/audio standard is the result of over 3 years of collaborative work ...
Audio Compression Techniques
https://www.mpi.nl/corpus/a4guides/a4-guide-audio-compression.pdf
Audio Compression Techniques Linear PCM (pulse code modulation) is a direct digitization technique for sound waves. At equidistant moments in time defined by the sample frequency and equidistant points at the amplitude scale, samples are taken, i.e. digital numbers are

Audio Compression ! LPC-based codec model the sound source to achieve good compression. ! Works well for voice. ! Terrible for music. ! What if you can’t model the source? ! Model the limitations of the human ear. ! Not all sounds in the sampled audio can actually be heard. ! Analyze the audio and send only the sounds that can be heard. !

The Complete Guide to Audio Compression – Icon …
https://iconcollective.edu/audio-compression/
Audio compression reduces the dynamic range of an audio signal. Dynamic range is the difference between the loudest and quietest parts of a waveform. Compression reduces this range by attenuating the louder signals and boosting the quieter signals. As a result, the loudest and softest parts are closer in volume, creating a more balanced sound. ...
