iTunes to MP3 conversion

[The General]

MP3 is a loseless codec.

Now I know you're full of crap.

Your're kidding? You must be.

Burning 192kbps and ripping 192kbps, he would not lose any quality.

...As tox1c said...except, AAC and MP3 are both lossy. More information:

The audio is going through two lossy conversions, when you go from M4P (AAC) > CDDA (CDA) > MP3.

This is because an AAC encoder and MP3 encoder use different schemes of encoding, and will manipulate information differently, as well as because they are both lossy.

You went to all that trouble to prove to me that I am right? Yes, MP3 is lossy, OGG is lossy, AAC is lossy, flac aiff and the sory are lossless. If you look back at his post he clearly says that MP3 is lossless.
*DISCLAIMER* I didn't actually read any of those links as I don't even care.



What is the point of this?

Burn to CD, rip from CD is the simplest solution. Besides, anyone who can hear the loss of quality from doing that wouldn't be buying music from iTunes in the first place. Or asking us for the answer for that matter.

... no.

In fact he clearly used the word loseless. You yourself highlighted this and responded to toxic the third post up with the phrase:

I went through all that effort to simply correct tox1c's use of the word loseless to lossless, as well as to support tox1c's argument that you will lose audio quality, because you responded to Tox1c with the following comment...

I would NOT recccomend burning and ripping, you will lose a bunch of quality..

get IMTOO Audio Converter, or any MP4/AAC - MP3 converter (LAME Encoders).

You want somethign like that (this isnt freeware tho

Your're kidding? You must be.

Burning 192kbps and ripping 192kbps, he would not lose any quality.

To add, although I sympathize with your disclaimer and your absence for any care...my intention was to provide references and information for those who do care (for example, if a user was to search TF to research whether converting from MP4 to MP3 will result audio degredation).

Plus, I did not know MP4 > CDDA > MP3 conversion would cause audio degredation, until I researched and discovered those sites. I cited from those websites and I found it only appropriate and right to provide references to the originating source.

This was the point .

Typo, sorry about that, I was trying to contrast the AAC (which as I said was "loseless" as opposed to the MP3 which is not loseless.. I simply forgot the crucial word "not".. I apologize.

If you read it you can see that I was trying to show the difference.

Alvin.C understood what I was tryign to say..

Again sorry about that.

 

[The General]

Do what you want, I proposed a simple solution, but using shoddy, probably virusized software is not always the answer.

Re: Re:

I saw this thread and was interested, cause I would like to do this too.... THIS statement though... I HAVE to disagree with....

...you can help eliminate audio quality degradation by ripping at higher bitrates than the original (for example, burning a 128Kbps M4P to CD, then ripping the track to MP3 at 192Kbps, so that more samples of the audio are being taken).

I am BY NO MEANS an audiophile, but I would have to believe if a song is burned at 128Kbps, it will be ripped at 128Kbps. Sure, it might SAMPLE at 196Kbps, but the QUALITY will still be 128Kbps.

Re:

Hello,

That's what I thought until...

If you're converting AAC files encoded at 128kbps to MP3, set the bit rate for the MP3 files to 192kbps. Otherwise, you'll lose a lot of information because MP3 is less efficient than ACC and will not be able to store all the information at the same bit rate.

JHymn Project

When you burn an AAC file to CD and then re-rip the CD as AAC or MP3, the sound you end up listening to will have gone through a lossy compression process twice. Those losses can add up, taking what were only mild or even unnoticeable deviations from the original sound after the first phase of compression and making those deviations much more noticeable and objectionable. This is especially true if you try to take music at a low bit rate like 128 kbps (what Apple uses for iTMS) and try to compress back down to the same low bit rate.

If you ever do end up having to burn and re-rip (the day is almost certainly coming when JHymn won't work, at least for a while, because Apple has updated their DRM), I recommend re-ripping your iTMS purchases as at least 192 kbps AAC files, or VBR (variable bit rate) MP3 files with an equivalent or better bit rate, in order to minimize the negative effects of a second generation of lossy compression.

He is converting from AAC > CDDA > MP3, not MP3 > CDDA > MP3. AAC and MP3 have different schemes of encoding, and will manipulate information differently.

I would agree with you however, if it were MP3 to MP3.
