I have an audio recording of.wav file type that i want to obtain the spl for it. the audioread() function returns 2 columns with doubles. how do i convert that into spl and plot a graph of spl vs time?
My goal is to obtain the L50 level of the sound recording

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.
