Sampling mode
infinite resolution into a digital signal with finite
resolution. With 16 bit resolution, each level is
indicated in 65,536 steps (the sixteenth power of two).
The greater the bit resolution is, the closer to the
original analog signal the waveform in memory will
be.
48 kHz 16 bit sampling is the same quality as in audio
devices such as DAT. CDs use 44.1 kHz 16 bit
sampling, which is a slightly lower sampling
frequency.
