Don,
Imagine a sound wave front coming directly at you, like an ocean wave. In
order to construct a digital representation of this analog phenomenon,
through time, you need to do two things: you must divide the wave front up
into discrete lanes (as it were), along its width; and you must measure the
state of each of these lanes, over and over again.
The number of 'lanes'/bits into which you divide the wave front at any given
second is the band width/bit rate, measured in kilobits per second. The
number of times you sample/measure the state of each lane, in a given
second, is the sample rate/frequency, measured in kilohertz per second.
Blessed Be, Namaste,
Dana
that's Dana, D A N A, NOT Donna, D O N N A
If your synthesizer pronounces them identically, instruct your customized
pronunciation dictionary that Dana=dayna.

Subject: Bit rate and sampling rate
This is ludicrous, I know. However, please help me to keep
these straight because I know when and how to change them, I
just cannot remember which is which. Which is the bit rate,
and which is the sampling rate?
Thanks.
