[LAD] Help to choose an audio library for a project

Hello, I'm student in computer science and for one of my projects, I would like to program an audio player. The player will be developed for GNU/Linux environment but I would like to use an audio library which permit a portability for Windows and MacOS X too. The player will must read files in wav, MP3 and OGG/vorbis (at first) and it will have an equalizer. I think to use C++ language with Qt library for the graphical interface but I encounter difficulties to make a choise for an audio library, that is why I thought to ask the question on this list. What would be the best audio library to program this kind of audio applications ? (SDL ? OpenAl ? PortAudio? or other(s) ?) Thank you by advance for your answers. Regards, -- .---.
