HN comment orderIn the same genre and likewise in Haskell, I recommend Exploring JPEG: http://www.imperialviolet.org/binary/jpeg/ On the decoder side, for someone who has basic familiarity with compression and signal processing, the obstacles in understanding MP3 are polyphase filter banks and the mixed discrete cosine transform, which are not much explained in this article. They both take advantage of alias cancelation properties (in the frequency domain for the filter bank and in the temporal domain for the MDCT) that in my…
Ever since reading "How music got free" by Stephen Witt I get a bit annoyed with the MPEG team getting credit for "creating" the mp3. They did more to kill it than to support it.
If you liked that, you might be interested in jpeg decoding in Haskell: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.25.6... I also found this literate source while looking for that paper again; cool! http://www.imperialviolet.org/binary/jpeg/
