raise a mp3 from 192kbs to 320kbs

good afternoon i have a folder of mp3 at 192kbs is there a program to raise them to 320kbs for best sound quality i have tried audcity but it seems very long winded

many thanks in advance

it is not possible, once quality is lost it is lost for good.

You thought it did, but that was just good olde placebo effect kicking in - nothing more nothing less, trust me on that, as we humans are prone to that now and then. Also, a bit of Dunning-Kruger, but I digress...

Just to illustrate what others have been trying to tell you, see the collage below:

The left half of this scene was encoded with HQ lossy settings, which, for this comparison's sake, can be said to be practically the same as the original file it came from (RAW, TIF or even JPG, it doesn't matter much here).

The right half is an equally lossy encoding of the same image - but this time with too aggressive compression settings - that's all there is to it.

So, if a program pops up claiming the right half could have its quality rescued or... "raised" as you said, you can, as per these scientifically proven data, regard such claim as just a truckload of BS, 'cause that ain't just possible - once the quality is lossily taken away it is never returned - that's why it's called lossy and not lossless encoding.
The same can be said of that lost "miraculous" program o' yours: it's just a lot of baloney - no "ifs" on that statement, sorry!

In fact, in view of what lossy encoding is all about, the term "raising lossy quality" sounds as ludicrous as the "raise" in "raising someone from the dead"!

Edit: disclaimers:
  • Naturally, the same unrecoverable quality can be said of the left half, but since its starting point has got fairly good quality, it's gonna take longer for anyone to notice any degradation. The right half is the left one "in the future", if we carry on lossily reencoding it.
  • Image, audio or video - it doesn't matter: all lossy encoding generates losses. I just used the image as it's more obvious to they eye (unintended pun, I swear).

I hope this helps.

Also recommended as further reading are HA's own wiki as well as Vorbis's "Monty" Montgomery's one as well.

Decoded it and re-encoded it using more bits - sure.  But "for best sound quality" - nopes, as others have told you.
In fact you get worse quality - technically, but it is unlikely that you can hear the difference.

You might have expected that if you don't get better quality, you shouldn't get higher bitrates - after all, there is a way to represent that signal in 192 kbit/s (proof: the file you have!).
And in theory, you can find back that file. But in a not-too-unlike theory, I can also read your encrypted files - all I need is to find your password. In practice, both are a "forget about it" amount of work, although only one of them was designed for the purpose of making it infeasible.

very interesting...
In metal high tones that can not even hear can be important for feeling. tones from other side. the dark side. use the bits Luke

It's your privilege to disagree, but that doesn't make you right and me wrong.

They'll become better if you start with 32 kbps fhg mp3 mono shellack transfers. It's just awesome.
Are we at Kindergarten level now? How could OP even find the internet? Questions. 120 postings and then... this? Something is wrong here.

Just my thoughts as well.
Something's definitely amiss...

*sighs*  good folks ... 
There have been situations where I have absolutely not objected to "troll" labeling, but this user has a history of asking how to get this or that in fb2k working. If the OP has been busy listening to music, fine on them - that's something I wish I had more time to.

This looks like honest question coming from ... well possibly, less honest software. Or merely by software that just doesn't bother to explain what operations are useful and what are less useful.

MP3 can be encoded from PCM and MP3 can be decoded to PCM. There's plenty of software offering both. It is not witchcraft to do both operations in reverse order. In fact: it is not witchcraft in the sense: it won't get you any magic.
We all know that. It's fair game to ask what those applications actually do and don't. And the answer is, they just make the signal even more lossy (but for these bitrates, unlikely to be any audible deterioration) - in addition to wasting space. Something you shouldn't do, and something software shouldn't recommend.

Marques Brownlee did demonstrated this once, he and his team uploaded a video to YouTube, downloaded it, and re-uploaded it and after the 1000th times you can imagine how it looked. The same it true to converting MP3 to any other lossy format.
