You shouldn't be upping your MP3 bit rate for no reason. You are an engineer, start thinking like one. The maximum bit rate you should output is limited by the maximum dissernment of the human ear. To say your ear can discern 320 kilobits worth of quantization is pretty impressive. From what I have read in the past, you start to lose dissernment at 192 ish bps which is why thats the gold standard for audio.
This is the same analogy as for TV resolution. Yah you can have 4000p TV's someday, but your eye can't dissern the difference from that or 1080p from the normal viewing distance and with a 50" screen.
Also, your audio perception is extremely limited to the performance of your output device. Most speakers in the consumer market can't render the full spectrum of 320 kilobit songs anyway. All this leads up to WASTED SPACE.

Km, I am sorry but you are full of shit. Listen to a score from a big name movie (such as star wars) in 192 and then listen to it in FLAC. If you can't notice the difference, then you need to get your ears checked. The problem is people don't realize how much they are missing when they get shitty mp3s. I dread the fact that I have to listen to GES music in anything BUT flac or lossless. Some of it isn't high enough quality to really make a huge difference for goldeneye, but just the thought of hearing mp3 again makes me shiver. All scores and audio I download are NEVER mp3. Mp3 is only good for the generic audio listener who doesn't have a very strong ear for all ranges (more than 3/4 the population). I have a decent stereo in my car and decent headphones that I didn't pay a lot for, and I can easily notice the difference. Take a listen for cymbals and bass especially. Those usually are what get distorted first in mp3s.....
Granted...all this is invalid if the original source isn't made with high fidelity...which a lot of recent day music doesn't have. Therefore, it wouldn't matter as much. Some artists still produce very high quality music, and its easily noticable in them in modern day stuff.
/rant..sorry, but audio arguments always get me fired up. I get upset a little cause I only wish people could really hear what the difference is. Sadly, one of my roommates can not tell a difference. The others can though. I can listen to a blind recording of two songs and pick out the lossless one everytime...:/ Anything less causes my ears to cringe.
basstronix:
Yeah I was hesitant to tell him the same story. Engineers and sound engineers... are not the same. I happen to be both :/
While his comment is accurate, what he derived from it is not.
killermonkey:
Saint, you call me out on not knowing what I'm talking about, then you go on a serious diatribe about how lawless and mp3 are extremely different.
Not to be rude, but DUH.
My commentary was clearly only talking about the bitrate differences between the same method of compression. Regardless of how many bits you cram into an mp3, you are still doing a tremendous amount of compression aside from the bitrate. This includes low pass filtering to about 16 khz, which is why you lose a lot of the cymbols and stuff.
Please don't go on rants until you've taken a signals processing class. Thanks :-)
I'm just going to drop this here (Not scientific): http://www.maximumpc.com/article/do_higher_mp3_bit_rates_pay_off?page=0,0

ah, sorry KM. I guess I didn't interpret that correctly. Usually I hear people talk about the difference between a 192mp3 and a flac as unnoticable, but what you were talking about was between mp3 compressions. My bad. I take back my shit talk I through at you. I agree with you fully. It is very difficult to determine a 320 and a 192 as they both filter out similar frequencies and sounds. Now if only everyone would realize that flac and mp3 are vastly different....that will take some time. :)
basstronix:
While I was surprised to see the difference between a good mix and a bad mix spectrally, compression did affect this judgement. However, compression generally removes parts you wouldn't notice anyway. That said... everything I stated still stands (I think?).
