A cheap one! save that $$$
I went to a private 4year mucho dinero school... I learned more in 3 months as an intern than in 4 years of college.
Some people need a school to get them started, I know I did! I couldn't have jumped into studio life straight out of high school.
nothing wrong with that.
Seriously, I have had a decent ammount of sucess and I'm still paying LOTS 6 years later on student loans.
I think private $$$ colleges are the bigest rip-off and scam going to day, with banks and student loan financers laughing all the way to the, well, bank (they don't have to go far)
A motivated student will learn outside the walls and books that his teachers assign to him/her. You don't need Ivy leage to learn.
Stick with a state school or 2 year technical college, Use the rest of the money on gear!
RANT OFF....
If you want the "how the engine runs" of digital/analog audio, your looking at a EE or perhaps a 2 year program in electronics... Yah you can learn the dbu's, dbv's, 0db FS, RT60's and all that good stuff, but your still not really learning the how's and why's...
I'd sugest if you REALLY want to know the nitty gritty... get at EE or ME degree, and go to a school that has an audio recording progam, and take clases in that, or perhaps minor it it...
