I'm in need of graduate level schooling on psychoacoustics and audio compression on the cheap. What are the latest and/or most used textbooks on these topics?

There are two studies involved here: the science of how humans perceive sound and the art of data compression algorithms. My aim is to understand the state of the art in the overlap of the two with an emphasis on psychoacoustics, which may very well require reading up on each topic separately. Regarding psychoacoustics, I'm looking for the most comprehensive text(s) available. Something that discusses and illustrates concepts would be good. Something that specifies the math behind various models and refers to journal publications would be ideal. Regarding compression, math/reference heavy is preferred, and I'm primarily interested in techniques and algorithms that take advantage of psychoacoustic models to exploit frequency/loudness thresholds, phenomena like temporal masking, etc. Learning the various ways to perform related transforms such as FFT, wavelet, etc is also within my sights. The idea is to gain an understanding of, say, the science behind MP3, then and now, plus the challenges/limits involved in furthering similar technology.
