Tips for determining audio quality
Generally, it is quite straight forward to determine the properties you should use
for recording a waveform. The determining factors are the file size and the type of
speakers the audio will be played back over. For example, if disk space is limited
and the sound is intended for playing over small computer speakers, then there is
no need for CD quality sound. Likewise, if you plan on playing your files over
amplified speakers directly from your hard disk, then you would want more than
just telephone quality. The following chart offers you some ideas of the different
types of audio quality possible and how they affect file size.
Quality Properties File size
(compressed: 10 secs)
Telephone 11,025 KHz, 8 -bit, Mono 107 KB
Radio 22,050 KHz, 8 -bit, Mono 215 KB
CD 44,100 KHz, 16 -bit, Stereo 1,720 KB
