loading a song

hello, i am new to Matlab and i am trying to use it for the first time. I am trying to make a laser show. I will output the 3 frequencies (low, mid and high) on laser. To filter the frequencies i will be using matlab. I found some examples to help do this but i have no idea where and how to load a song. I have the song in .wav. Can someone help me. thanks

wavread() to read in a .wav file.

See what should be done, if we want the complete song to be analysed, or at least half of it..!! Wavread is not beneficial in songs, right now.

wavread() allows you to select a range of sample numbers.

The replacement for wavread() is http://www.mathworks.com/help/matlab/ref/audioread.html which also allows samples to be selected.

If the song does not fit in memory you are going to have difficulties in analyzing it if the analysis depends on the properties of all of the samples.
