Sampling mode
the interval is 1 (second)/48,000 (times) = approximately
0.00002083 (seconds) = approximately 0.02083 ms
(milliseconds).
The higher the sampling frequency is, the closer to the
original analog signal the waveform in memory will be.
Each level is read, and converted into digital data. The
accuracy at this time is determined by the bit resolution. This
process converts an analog signal with 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.
