Use the Audio Toolbox function splMeter.

yeap i managed to get my graph up and running. But do you know how I can obtain the L50 sound level from it? or from the audioread() file?

I do not have the Audio Toolbox, so I have no experience with it. I am not certain what all its options are.

The median function can return 50th percentile value of a vector, and the prctile function can return the percentiles of a data set. See the documentation on each for details.
