Hello All,

I have a question I've always wondered about.

I can see how an audio converter can change a song with a higher bitrate to a lower bitrate.

But, how can it change a song with a lower bitrate to a higher one?
Like when takng a song of 128kbps to 320kbps. Naturally the 320 will have a larger size, where do the extra bytes come from?

Thanks in Advance

What program can do it?

I think it is not even possible... Or it can be, but sound will not be any better.

you can re-encode it to a higher bit rate, but the quality of the music will no improve. you can't pull data that's been removed out of the air and have it be there sounding good.

OneMember there are tons of programs that can do this.
Just do a Google search for audio encoders.
Personally I use WavePad.

it's just expanding on the data that's there, similar to (but not exactly like) blowing up a picture in photoshop.

Auslander's correct on this one to be sure. a 128kbps file had lotsa stuff removed, permanently. When you try to get it to 320kbps you're still dealing with the data from the 128kbps file.

Here's the thing:

When I rip my CDs to the computer I do it at 320, but if I download a song that claims to be 320, is there anyay of knowing if it actually came from a high quality source or a lower quality bitrate and then converted to 320?

I do not know why anyone would want to do it because it would take up more HDD space or fill up your MP3 player and just sound the same.

no way to know; that's the risk you take with downloading.

Personally I can't tell the difference between 192 and 320, apart from file size. It's one of those show off things "all my music is 320 or above".. What's the point?. Until you get below 170 there isn't any noticeable difference, and even as low as 44 is acceptable to people who grew up with vinyl.. unless you have exceptional ears, and really high end sound equipment. The human ear isn't exactly a high precision device. The weak links in music have always been the analog devices at either end.. microphones, speakers and ears.....

I am in the same boat, can´t tell the difference. That is why I use 128 when I rip music.

Also when I listen internet radio I hear no difference...

mikle4,

I'm seeing way too many one-line fluff posts from you. Post padding is not allowed so I better start seeing some quality posts from you.

come on ye guys are pulling me leg..,ye take a AVI file of 25meg and compress it to 4 or 5 meg at 128kbps mpg and it sounds good.
even at 320kbps it does not sound as good as the original AVI file

Below is the truest statement i heard in a long time..

mp3 do not have the good quality of the old records.
and i do have a ton of records i put on tape..
and the best part i did not have to use a computer or worry about copy protection...

The magic is gone

I remember buying records when they were vinyl. I loved nothing better than to set them up and listen to them on a good stereo and plow through the artwork.

There was something magical in that sense of it belonged to you.

I'd take off the wrapping, carefully slide it out of the wrapper, lay it on the turntable, clean it, and then carefully adjust the controls while it started playing, and then lay back with that artwork and just enjoy the magic.

That's no longer part of the listening experience. The magic is gone. So is the artwork.

With the mp3, the ambience isn't there and I can't hear the stick hit the cymbol before it rings. Nor can I hear the guitar pick hit the string the moment before the string rings. What's worse, the price for this junk has gone up and I can't legally put it on the reel to reel to enjoy as a long playing tape that doesn't need to be fooled with for a long time.

Mp3's don't do it for that sort of equipment. You always hear what's missing and notice it's missing. That's not quality. Nor is it worth a dollar for that sort of sub-par product, even if the artists were as good as they were then (and they're not for the most part).

I see nothing desirable in the music today. Not from the subject range, not from the artists, not from the quality. Worse, the majority of the music I see today that I might be interested in, I already have. I don't need to buy Greatest Hits because I have the originals. Those originals are not hampered with any sort of anticopy. If I want a cassette, ok, if I want a CD, that's ok too.

No hassles and no issues in how I want to use them.

Someone in the cartels has forgotten that how the buyer wants to use the music is everything. Without that, there isn't much need in buying a rental limited edition that isn't worth the money to begin with.

But let's really make it good and give out free rootkits and spyware that you can't cancel or refuse. Yeap, sounds like a real bargain to me.

Yeah, I rip music at 128kbps as well. I can't tell the difference between 128 and 320 on my Zune. Especially when I rip music using the LAME MP3 Encoder in EAC. 128 saves me space for more music too.

@ ireland.

That is a lovely piece, and explains how I feel about digitised music.
I can hear the difference between some of the great recordings of the 60's on cd or on the original vinyl. It is very apparent with some of the quieter music, Melanie especially. It could be that they were encoded a long time back when the software wasn't as precise.
There are some stunning analog recordings. Find a copy of Jimi Hendrix live. A nice old one on any Ember blue label will knock your socks off.

I agree that we have been robbed of quality and freedom. I'm lucky that when everybody else was dumping the vinyl technology I bought some superb equipment very cheaply.. who wants this old stuff? I do for my large collection of real rare 60's garage and psychedelia.. some are even mono!
Maybe I'm a luddite, but I like my vinyl.

I still got all the stuff to play my vinyl. Nothing like the little clicks. Actually got a second Dual 1219 turntable free last year. Cartridges have gotten a little expensive tho. Listening to Close to the Edge-Yes, on Vinyl now.

i do not buy cd's as to me they are not worth the time or money i use cassette 90 min on each side,all recorded from records,if i bring them into my computer the file format is AVI not the crapy rip off stuff...128 or 320kbps mp3..

a AVI file can be put on cd as it is..i do have Jimi Hendrix live.
and a ton of irish music on vinyl..i even have the records that are on 78rpm..from when i was a kid..example i have all FATS DOMINO on 78rpm,transfered to tape..i have all the album's of the BEATLES on 33 1/3rpm and more........

i say the kids today do not know good quality music as we heard as kids and now...they are being ripped off from the music studios..and the jirks at apple with there ipod DRM...and 128kbps crap..

the junk they buy for 99 cents just don't cut it,no quality..
when i play music it through a tube amp i build..

Quote:
Tube records have more bass....The bass actually sounds an octave lower," says one rock guitarist. A couple of professional studio players have pointed out on numerous occasions that the middle range of tube recordings is very clear, each instrument has presence, even at very low playback levels. Transistor recordings tend to emphasize the sibilants and cymbals, especially at low levels. "Transistor recordings are very clean but they lack the 'air' of a good tube recording." "With tubes there is a space between the instruments even when they play loud...transistors make a lot of buzzing." Two people commented that transistors added a lot of musically unrelated harmonics or white noise, especially on attack transients. This same phenomenon was expressed by another person as a "shattered glass" sound that restricted the dynamics. It was generally agreed that tubes did not have this problem because they overload gently. Finally, according to one record producer, "Transistor records sound restricted like they're under a blanket. Tube records jump out of the speaker at you....Transistors have highs and lows but there is no punch to the sound."

256 vs. 128 kbps: Can You Tell the Difference?

http://blogs.pcworld.com/staffblog/archives/003993.html

Wow. This is some kind of day. Baseball. Rock Band--an upcoming Guitar Hero sequel with bass, drum, and vocal parts (!)--was announced for the PS3 and the XBox 360. Oh, and DRM-free music from EMI. Clearly I'm pretty psyched.

I applaud EMI for making DRM-free music available to online music stores, and I'm glad it comes with a boost in audio quality. Apple will offer the option of converting any eligible iTMS purchases for $.30 a piece. But I'm sure there are at least a few people out there who are just fine playing their $.99 128kbps tracks on their iPods. The new DRM-free files may be twice as big, but that doesn't mean they'll sound twice as good.

(Demo below requires the QuickTime plugin.)

So is the boost in quality worth it? I certainly think so, but then I'm a bit of a freak about sound quality. Here's a quick way to see for yourself. I dug around the office for some CDs and ripped a couple short clips (nothing over 20 seconds) in both 128 kbps and 256 kbps AAC. Download these files, give 'em a listen and let us know if you can tell the difference. Or for an even better test, fire up iTunes and rip a few of your own CDs at different bit-rates. It's cool. I'll wait.

Or just play the files right here:
Mozart in 128kbps

Mozart in 256kbps

We also have a short sample of "Man on the Moon" by R.E.M.
R.E.M. in 128kbps

R.E.M. in 256kbps

So what do you think?


The difference is more obvious in the 256kbps Mozart piece (the strings don't sound so "mushy"). The R.E.M. 256kbps excerpt has more clarity or brilliance. Now, I'm listening on headphones and I usually don't mind casual (brief) music listening this way or on my PC's speakers. However, it's my personal experience that almost anything encoded at less than 320kbps played on my living room stereo system draws my attention to the low quality and it quickly becomes annoying because of that.

Buying music at 128kbps is like buying a book that only shows every other letter - you don't experience the work as intended by the author. Remember, lossy compression is named that way for a reason.

My day job is building and operating extremely large concert audio systems. Low bit rates MP3's are quite obvious even to the untrained ear. Totally acceptable for my computers multimedia speakers, but in a high quality audio environment, nothing beats a good old C.D.

GO HERE TO HEAR THE DIFFERENCE,YE NEED APPLE QUICK TIME TO PLAY THE TOONS

He has the same day job I used to have.. Live sound system op.

Nothing beats a great live band, and I have seen some of those in my time.

My setup disks on the road were Joe Satriani and Robin Trower.. Sat for the clean power and dynamics, and Trower because there is a depth to the Bridge of Sighs recording that is so missing from almost every modern multitracked work. The title track (especially off vinyl) has to be heard to be believed.

I have a really nice copy of this.. almost totally clean, surprising as it's from way back (74 I think) which is deserving of a lossless rip. The one I got off some torrents a while ago was 320, and crackly... not to mention FLAT!!
I remember this album being the first thing I ever saw on CD, for a philips £2000 odd cd player and came with it as a demo.

I think the real shame of the digital age isn't so much the technology as the total garbage the big4 are pushing down our throats..
What ever happened to taking a risk (remember Stump?) and giving the public something different for a change, instead of the constant diet of talentless rap, r&b (rubbish and boring.. when did r&b mean black artists only? The Stones are an R&B act.. according to the "file under" instructions on my copy of Aftermath) and created girl and boy "bands", I use that term very losely.. really I mean "no ideas of their own talentless karaoke singers"..

To quote the Jello Biafra

"Is my cock big enough, my brain small enough.. For you to make me a star...
Give me a toot, I'll sell you my soul.. Pull my strings and I'll go far"

Remember Pop Will Eat Itself?.. weren't they so right?

Oh.. the same goes for digital TV.. ever watched something like a motorsport event and ended up thinking you were watching a computer simulation, not the real thing? When we eventually lose all analog broadcasting they will control everything we see and hear, and we will not be able to tell reality from digitised fiction. I don't know why. but I don't somehow like the idea of that.
