A) Integer encoding limits A 8-bit audio file contains sound pressure levels encoded as 8 bit signed integers. - Compute the minimum and maximum values that these integers can take - Compute the ratio between the amplitude of the loudest sound wave and the softest nonzero sound wave that can be encoded in this file - Express this difference of sound volume in decibels (dB). This parameter is called "dynamic range", and corresponds to the difference in intensity between the loudest and softest sound that can be recorded on a file. Any sound softer will not appear in the recording, and any sound louder than the loudest possible level will be clipped (https://en.wikipedia.org/wiki/Clipping (audio)) B) Encoding of float numbers In this problem, we focus on the problem of encoding float numbers on a computer. We recall some useful formulas: - Scientific format in base 2:x=s2e where 1s
