Why do some companies rate digital announcers using the kbps scale while others use KHz?
Thats a very good question and its too bad that all companies dont express their scores in the same manner so consumers can easily compare product audio quality. Well be happy to demystify this simple conversion so no one can pull the wool over your eyes. Weve already explained in our previous question the levels we consider to be Low, Medium and High using the more typical kbps (kilo-bit-per-second) sampling rate scale so all thats left to do is to give you the formula used to do the conversion. When converting from KHz to find the kbps rate simply multiply the KHz number by 8. For example; A previous #1 announcer was the DP-100 and it had the ability to sample your audio program at three different rates; 11-KHz, 16-KHz and 22-KHz. When doing the math you find that the three sampling rates (when expressed in kbps) are 88-kbps, 128-kbps and 176-kbps (8 times the number in KHz). So put away your calculators and dont be fooled by products expressing their quality vaguely.
