Help With Audio Bitrates and File Sizes. - Page 2

post #11 of 19
128kb/s is typically considered to be CD quality, thought i think 192kb/s for me is the sweet spot. As others have said, mp3 compresses the files, as your goal is to reduce file size stay with mp3. Test what rate sounds ok to you. Convert 1 song down lower then 128, listen to it, then try the same song at 128, 192, etc until you are happy with the quality to size ratio.

A really simple illustration of the difference in analogue and digital audio (to the best of my knowledge). The top left is analogue, its a wave. The top right is digital, its like ridges with plateaus and canyons. The bottom is a lower bit rate on the left and a higher bit rate on the right. The higher the bit rate the more ups and downs in the same period of time to imitate the analogue signal. The closer the "steps" get to the original analogue wave the better the quality.

I agree with the other posters that 192kb/s is probably the sweet spot for you not to notice. 128kb/s is ok too, but you will start to notice the difference between that and full quality, whereas you are more unlikely to at 192kb/s. 128kb/s is the space saver, 192, is saving some space without a noticeable drop in quality. Personally, i'm in the 320kb/s crowd biggrin.gifthumb.gif

Thanks guys, I don't personally notice any difference between 128kbps and 192, or even 320 for that matter. But that could be contributed to my speaker setup.

Again, I appreciate all the helpful input, it makes things easier to comprehend.

Un, no. Digital isn't "waves" square, round or otherwise. You can't draw a picture of it. It's Just a bunch of numbers the "represent" the original analogue signal.

When you convert those 1's and 0's into a signal, you get a graph like he described. It can be interpreted in its basic form as a waveform. Square waveforms, Interpreting clock rate, and such. Convert a signal of 1's and 0's into an oscillator, it will give you a square waveform.

Yes Just stick with 128kb best compromise for you and your setup.. ..


Who stated they are getting Feedback and distortion in their system that could indicate a more serious problem.. Have it looked at..

I stated that, I had it troubleshot to the stock stereo in my vehicle. I installed the new radio today, sounds leaps and bounds better.

But we don't listen to graphs, nor to digital 1s and 0s.
We listen to analogue signals through analogue amplifiers played through analogue speakers.
We use DACs to convert the 1's and 0s back into an analogue signal. And those recreated analogue signals are not a bunch of square waves.

You're correct, but representing them at the time they become digital signals, they can be visually interpreted into a graph. Mostly just for people to "see" what the computer or device is actually doing with those numbers. It is not meant to be taken in a literal sense of "that's what it looks like". Just that if you take a signal, convert it into a digital format of 1's and 0's, and turn that string into a graph form, where essentially they mean On and Off, that could be graphed out visually into a rudimentary square wave.

I understand what you're saying though. That audio can't simply be represented in a simple wave or graph form. Lots of things come into play when you take an analogue signal, convert it to digital and then back to analogue.
