difference between 44000Hz and 48000Hz

[dischinaman]

can anyone explain the difference between 44000Hz and 48000Hz Stereo for mp3s?

Yeah I would be interested in knowing the difference as well. I have one album in both frequencies and noticed the 44k was slightly softer but I think that was just the encoding. The only thing I know about them is that 44k is based on CDs and 48k is off DVDs. Anything else I'm clueless.

I hope this helps.

if you can hear the difference between the 2 with normal speakers/headphones(not monitors) you have some great hearing

I would say it is impossible without monitors.

And by the way:

Humans can generally hear sounds with frequencies between 20 Hz and 20 kHz (the audio range)http://en.wikipedia.org/wiki/Ear

Actually there is no big difference, 44kHz is enough in most situations. (Some audiocards even resample internally from 48 kHz to 44kHz)

The bitrate effects the sound you are hearing much more gravely than the sampling rate ;)

totall agree to all of you above

44k and 48k is the sampling rate for digital audio. in theory higher sampling rate better it sound and more realistic it will be. since our ear can't determine which one is better between 44k and 48k. the difference we can tell is on the file size of these 2 sampling rate audio file. of coz the 48k is larger in size

i think that difference is meassured at certain audio softwares,for editing or something,because in quality, it sounds the same for me

The human ear can only process up to around 20 KHz, 44 KHz comes from Nyquists law regarding sampling (i.e sample at, at least twice the highest frequency). The difference between 44 KHz and 48 KHz wont be noticeable to the human ear. I think DVD audio is sampled at 192 KHz, not sure why though!

example - draw a sine wave

place 44.100 dots on a piece of paper and connect them to draw the wave

place 192.000 dots on the same size piece of paper and draw the wave

which is more accurate and contains more information?

it's true that the human Nyquist is around 20kHz so it won't be audible (maybe it can be felt?) but the higher sample rate gives better possibilities in clearer, higher defined and distortion/interference free audio signal.
that's the theory.
which is theoretical.
