java - Obtaining Sound Pressure Level of wav file - Stack ...
https://stackoverflow.com/questions/24110333/obtaining-sound-pressure-level-of-wav-file
This is what I am doing: First of all, as the wav file is saved in 16-bit PCM, I operate with its bytes to have an unique double value normalized between [-1,1] ( I don´t operate with the first 44 bytes as it is the wav header). Then, following this equation SPL=10*log (audioSample/Iref) I obtain each of the desired sound levels (being Iref=10^-12).
