discrete cosine transform . Specifically, we only retain those coefficients that cumulatively sum to a large part of the signal energy. Here, the signal is an audio file, where only 13% of the DCT coefficients are needed to represent 97% of the signal energy. After compression, the resulting audio is hissy but still legible.

http://ijettjournal.org/2015/volume-21/number-5/IJETT-V21P247.pdf
DCT Discrete Cosine Transform can be used for audio compression because of high correlation in adjacent coefficients. We can reconstruct a sequence very accurately from very few DCT coefficients. This property of DCT helps in effective reduction of data. used in DCT.
