(I wanted the title of this post to be "Looking for a good technical introduction to perceptual audio coding" but that didn't fit well on the front page)

I want to spend some time reading technical papers about perceptual audio coders, so when Frank starts saying stuff like "No that's wrong because of the (insert technical babble here)", I might be able to follow along. smile.gif

http://ccrma-www.stanford.edu/~bosse/proj/proj.html: I discovered this page in a Google search. It seems like a fairly comprehensive introduction to perceptual audio coders, and although it's dated 1998 or so, it looks like it has a lot of relevent information.

I just wanted to make sure, before I spent several hours trying to read and understand it, that it's not a false/poorly written article. And after reading this, I'll probably want to read more...

I appreciated 2BDecided's links to articles on dither in this thread, and I'm wondering if there are some more bookmarks that the audio experts would be willing to share regarding the innards of audio coders.

I have access to a university library (which has subscriptions to a lot of technical journals) so if anyone can point me to some authors, journals, or articles that are good sources but aren't free to access, that would be great too.

I'm still a novice with this stuff, and my math knowledge isn't that advanced (yet), but anything that I might be able to understand would be much appreciated!

The Pohlmann is really a MUST for everyone interested in technical digital audio.

It is written well with less errors and with a
lot of British humor.

Note the remark about the Planck limit of
audiophile high resolution recordings.
