How is raw sound data stored?
I am using SPBRecord to create my own voice-activated recorder. In order to do this i need to find some way to access the meter level (ie the volume level of the data - an integer from 0 to 255) from the raw data recorded into the buffer ( i think is sample points in the form integer -128 to 127). How exactly is the sample data stored and how can i retrieve the volume level from this data?

I guess what i really want to know is how do i read and manipulate individual samples. Is there some code somewhere i can use to do this?

audio is generally stored as byte arrays since these are the easiest to compress, manipulate, and store. The exact encoding and decoding between recording and listening I don't know, the applications decipher the byte arrays. You might be able to access it using Resedit or something liek that, but watch out cause you could screw something up royally with resedit. good luck, hope this helps
