While listening to music on my Moto. i saw 44khz/128Kbps. Now I know one of it means sampling rate....But which one and what the other one represents?

 

Hello,

It probably has to do with the sample rate and bit rate.
See this page for more info:

This is a link from the EDUCYPEDIA on audiofile formats:

On the x-axis, if the number of "slices" is high, you have a high sample rate.

On the y-axis, if the number of "levels" (or possible discrete values) is high, you have a high bit-depth.

To clarify the second one, if you were to lower the bit-depth, you would limit the number of discrete values the amplitude could be in your music, and you would hear "stepping". It's actually a common effect used in electronic music. I'm sure you've heard it before.. Listen: http://www.youtube.com/watch?v=BbsrIebJ2Bw

Increase either and you're increasing the bit-rate of the music. i.e, number of bits per second.
