4. Digital audio
4.1 Scanning parameters
The values of the parameters of the sound digitization process and of the native digital audio format generated, vary according to the quality levels required by the uses (table 6 ) and answer the four basic questions (figure 7 ):
what is measured. The amplitude, measured at a given instant, of the analog electrical signal generated by the microphone translates the variations in sound pressure (the frequency band indicated makes it possible to specify the level of...
