Audio sample rate (kHz)
This rate is the number of times per second the original waveform
is translated into digital form. A higher sample rate results in a more accurate digital
representation of the sound. The sample rate for CD-quality audio is 44,100 samples per
second.
Bit rate (kbps) This rate is the number of bits a digital file uses in a specific time period,
usually expressed as kilobits per second. The higher the bit rate at which an audio file is
encoded, the higher the sound quality. 128 kbps is a commonly used rate.
