MP3 and C++

Hi, I'm working on a project for the university and I'm looking for 
some C++ library or application that could help me.
My goal is to extract some kind of information related to the 
spectra of a signal coded in MP3.
I'm looking for a spectrum analyzer that localizes peaks in the 
power spectrum (better if it works on a user-specified band) and 
allows the detection of the temporal occurence of each peak and its 
intensity.
I also need to retrieve some sample of frequency components (or the 
MDCT coefficients) near the identified peaks.
Every suggestion is welcome (even something that satisfies only 
partially the requests or that indicates a better place to found an 
answer to this message).
Thanks in advance for the help,
Gio

PS: even some function that works on the MP3 file without decoding 
it, for example only partial decoding actions (IMDCT, Huffman 
decoding) or subband value retrieval function, could be useful.
