If Audio CDs are 44KHz, does 48KHz MP3 encoding matter?

[novon]

Will there be a difference between a 44KHz and a 48KHz MP3 if the source is an Audio CD???

first off, this is general HARDware (sorry gotta nag about that ), and second, there is no point in encoding at 48khz. just encode at 44.1. what you should be worried about is the bitrate you encode at. check out the forum faqs, theres a great faq written about ripping cds / encoding mp3's.

Ehhh, if I'm taking you right then that would be a no, just think of Khz as Kbps.

Sorry that's just wrong. Kilo-Hertz (sampling frequency) and Kilo-bits per second (bit rate) have nothing in common.

The KHz rating of a sample tells you how often it is sampled (44100 times a second or 48000 times a second). The bit rate tells you how precise those samples are, the higher the bit rate the more acurate numeric representation is stored for each of those (40000+) samples.

Edit: Have a look at this little picture the blue lines (from bottom to top) represent the sampling frequency (imagine 44100 a second) and the bit rate (or bit value) is the accuracy with which the intersections (red dots) are represented as numbers (long fractional floating point values).
