At the time , company engineers needed to store audio samples temporarily on video tape , and the video recorders of the day worked at precisely 44.1 kilohertz in order to match the number of inter-laced lines and the scanning rate of japanese television sets .
But why sample at an odd number like 44.1 kilohertz ?
但是为什么要采集这个奇怪的44.1千赫频率的声音呢?
One megahertz is the same as one thousand kilohertz .
作为一个兆赫是一千千赫相同。
Radio station frequencies are often given in terms of kilohertz .
电台的频率常常以千赫为单位。
That was partly because it comfortably exceeded the nyquist minimum ( 40 kilohertz ) , but mainly because sony found it handy to do so while developing the cd with philips .
