A second factor in converting sound to digital form is the sample resolution. sample
resolution or bit depth indicates the precision in measuring the sound within each
sample. Three commonly used sample resolution values are 8 bit, 16 bit, and 32 bit. As
shown in Figure 7-4, increasing the sample resolution creates a digital sound file that
represents the analog signal more accurately, but this results in a larger file. For most
applications, saving sound files at the 16-bit resolution provides a good balance between
sound quality and file size.
