Answer
Dear Ken,

In digital recording the "x" refers to the maximum times the recorder oversamples the source. Since digital recording is done by taking a sample (say, every eighth data bit--tho' I have no idea what what the real rate is) of each byte (composed of eight bits) in the data set. Although you'll get something you'll easily recognize, you won't get it all. So, the recorders sample again--not from the remainder but from the whole data set. The more times a data set is sampled, the more representative the recording is of the data set.

Bottom line: the higher the sample rate, the higher the fidelity of the recording; i.e., 4x is "better" than 1x.

However, be warned. With Panasonic recorders, the "x" factor indicates the fidelity of the gray scale during video playback. Again, the higher the number, the higher the fidelity.

Good luck. And thanks for choosing allexperts.com!
