What is the unit of data?

I have a problem.What is the unit of signal obtained by sampling?

I find that the maxinum value I obtained by sampling is 1.

Has the data been processed?

If so, what is the parameter based on?

Thank you!

Please let us know which product and provide more info. thanks.

I use ReSpeaker 4-Mic Array for Raspberry Pi 2B by portaudio on Ubuntu.
