Atrac dead?

Hi!

I wonder why so many users of this forum regards Atrac as a dead codec, like in this thread: http://www.hydrogenaudio.org/forums/index....c=49803&hl=

I could think of three reasons:

a) Atrac sounds worse than other codecs (?)
b) Atrac is supported by too few players
c) The users are forced to use SonicStage.

Regarding a) I have searced these forums, and found one listening test from 2004 where it came out last among the tested codecs. But I haven't seen any other tests with the more recent Atrac3 Plus, except for Sonys own labtests, where it, not surprisingly, is rated best. (http://www.minidisc.org/keep/ITS_test_report.pdf). But that test is also old (2003).

Regarding b), it's true that Atrac is supported mosty (or only?) by Sony's own players.

And regarding SonicStage, I have heard a lot of complaints. I started using it one year ago, and since then they have upgraded the program a number of times. Personally I think the program does a decent job - I can't see why it should be worse than most of the competition. It now also rips very fast (version 4.2). I just checked the ripping speed. One 46 minutes album (image file) ripped in 55 seconds in SonicStage, and one minute twenty seconds in Windows Media Player 11. I guess that EAC with Lame would be a lot slower than WMP11.

Personally I am now ripping my albums to both Atrac 3 plus (64kb) and to MP3. So I rip an image first, and then use SonicStage and either Windows Media Player or EAC with Lame to rip to MP3. The reason is that I own two portable players, a HiMD minidisk and a Pocket PC. I like both very much. The minidisk is ideal for trips, because I can store most of my collection on a few disks. Plus it uses normal AA batteries. One battery last 34 hours, so I don't have to be close to a charger. It can also do high quality recordings. With the Pocket PC, at home or when I am in a wi-fi sone, I can access my complete record collection on harddisk over the net. The Pocket PC can also do so many more things besides playing music. So I think that both units are better value for the money than MP3 players.

Both players has another one big advantage over most MP3 players, and that is gapless playback. I think that gapless playback is just as important as the sound quality. And if you want gapless playback on MP3 players the choice is quite limited. As far as I know it is currently only supported by the latest Ipods, plus iRiver?, and maybe a few others. Plus it is supported by Sony players with Atrac files.

To me Atrac 3 plus at 64 kb sounds fine. I haven't AB tested the Atrac files to the MP3 files, which are encoded at a higher bitrate, but I doubt that I would hear much difference. My ears are not trained for that (they are only trained to hear the musical details, as I am a musicologist.)

To conclude: I think that the Atrac codec is not quite dead yet, and I hope that it will survive and develope further.

I don't think ATRAC is dead. It's just becoming meaningless. Like other well known codec in these forums (that I won't name here or people will claim I'm being a troll  )

IMO, ATRAC is not a bad encoder, especially at low bitrates (<160 or so) so I think ATRAC's bad reputation is coming from your B and C points.  My grandfather used to rip to ATRAC, and was very happy with its quality, so I never tried to stop him.

Regarding the MD player, I've used a Sony MD player (can't recall the model; it wasn't mine) and was also pretty happy with it as far as battery life/storage capacity goes.

In conclusion, I do not think ATRAC is dead, and if you can stand SonicStage, it's not a bad encoder.  I too encourage its further development.

1. Can you back up your claim that ATRAC is a good codec < 160 kbps with some scientific proof, like ABX? 
2. What do you mean by "good" codec?

Well, I COULD back it up with some ABXing, but since it's just an opinion I think I can get away without it.  If I were comparing it to anything specific or was less vague, I'd be sure to.

Exactly.  To add to that, as long as one person is happy with it, it can't be truly "dead".

Wow. Backed up by so much scientific proof we can now tell for sure, that neither bad nor dead codecs exist in the world.

EDIT:
I am glad that you brought your brilliant reasoning to my attention.

Sony's www.connect.com was talking about ATRAC being the format that their audio was encoded in and how it was "more superior" than any "normal mp3". However once I finished downloading the 10 free tracks I got from buying two 50 packs of Sony CD-R's I noticed that in SonicStage the audio format was called OpenMG. The quality in my opinion wasn't that bad (they were also seemingly all 137 kbps, don't know if they were VBR or CBR though) - but it wasn't good enough to invoke a purchase (good thing they were all free).

I don't know if the format was ATRAC in some container format or not, but the format won't ever make me switch from LAME's higher quality encodings, e.g.; -V4 and above, let alone aoToV compiles of Vorbis at -q 4 and above.

If I had erroneously taken your reply as bitterly sarcastic, I would have to say that it did not contribute in any way to this discussion.  But I know you were being serious, so it's okay.  Thank you for the compliment.

Why don't you tell me about what you consider a bad codec?  That would certainly contribute.

And please, tell me if you think ATRAC is dead.  If so, why?

i'm not really an open source geek, but atrac is so fantastically proprietary that using it is insane.  honestly, your music might well be inaccessible in as little as three or four years... hardware discontinued, no sonicstage for vista, whatever.

the only store selling it is sony connect, the only hardware playing it is sony... and didn't they make some portable player that would ONLY play atrac, ie transcoded any mp3s you tried to feed it?

the apple system is equally proprietary, but a) aac is an open standard b) apple lossless decoding has been open sourced and c) the ipod plays mp3 just fine.  that leaves only m4p, in which case it's not the codec that's screwing you (aac is a perfectly competent format), it's the drm.  sony connect screws you with both.

an anecdotal litmus test*: i a) work in a recording studio and b) totally get off on this audio compression stuff.  despite having a zillion tools across two operating systems that can do pretty much anything under the sun with regard to audio, i still don't have anything that lets me read atrac.

just some thoughts.  i don't care about atrac enough to give a damn whether it's considered alive or dead.

(enough people like me, and that makes it dead, i guess)

*not scientifically sound a la abx

Atrac is "dead" because:

1. Since by encoding your music to MP3 will allow compatibility with non-Sony DAPs, why use Atrac? Now, most Sony DAPs support other more popular codecs (MP3, WMA, AAC) anyway, so why bother with Atrac? Even HiMD units since the 2nd gen can playback MP3s natively now.
2. In the past, 1 big advantage for Atrac is gapless playback on Sony DAPs. Now, with iPod being gapless using a more mainstream MP3 and AAC, why bother with Atrac?
3. Sony doesn't even seem to support Atrac anymore. Sony Ericsson cellphones never support Atrac. Non-PCDP AtracCD devices never support seamless (gapless) playback of AtracCD.
4. Bitrate support on Atrac devices are not standardized. User can encode to 1 bitrate of Atrac in Sonicstage, but it might not be supported on the user's own Atrac device (eg. AtracCD), forcing the user to transcode to the supported bitrate. Imagine having an MP3 player that only support 256kbps and 128kbps CBR bitrate, not 192kbps, etc.

You don't have to even go into SQ to realize the severe limitations of Atrac.

ATRAC isn't a bad format from a technical/quality point of view, but is there any reason to use it now that most new Sony products support AAC and MP3? It's not dead (lots of Sony ATRAC-only products are still around), but it's doomed in the long run, and Sony has implicitly acknowledged that.

IMO the unwillingness to dump MiniDisc and ATRAC when it became clear that they were lemons has been Sony biggest mistake in the last 10 years - mp3 players have completely wiped out its dominance in portable player business.

b) and maybe c)

I actually brought a Sony CD Walkman - that can also play Atrac CD's - a few months ago. But it also plays mp3 disc's and I already have mp3 files.

I did rip a few mix CD's to Atrac to take advantage of the gap-less playback, but Sonicstage took ages to write them to a CDR so I don't think I'll bother again.

The reason to use Atrac instead of AAC or MP3 on Sonys players is that you get gapless playback.

And minidisc is also a recorder, a very good one. So why should Sony dump them? What alternatives do you have today for a portable recorder?

The reason why minidiscs sell less than MP3 players might of course be that most people don't need recording. But these devices also don't get any attention in media, just like Pocket PCs. And in my opinion both devices are better value for the money than MP3 players since they do more things.

Although there are mp3 players that also record.

atrac (the original format) that was on the 60, 74 & 80min mini disc I think is pretty much dead.

atrac3 and atrac3plus are the latest ones and by no means they are dead. Its actually the only codec I am comfortable with at the 64kbps bit rate (the one that I rip my Cd's into).

ok he-aac is really good and mp3pro isn't bad, just there are a lot more devises that play atrac3(plus) than those formats.

just my 2cents

And all because Sony didn't include the codec on the phone doesnt mean its dead, they are still making daps that use that codec, the psp is one.

and the main thing that you should note.
atrac3plus has better battery life than mp3 with the same bit rate and better quality. <- that's why it should be used!

Why do you think that?  Have you compared units that support both formats?  If so, I'd like to see the results.

They haven't dumped it because, just like DAT, Minidisc completely missed its intended market and hit else were.  Lots and lots of theatres use MiniDisc to play sound effects off because of the ability to name, re-order and edit tracks and instant start and auto cue on the majority of players.

In fact I've only stopped using MiniDisc for this purpose since I've discovered QLab ( http://www.figure53.com ) which is a media time line program for Mac OS X.

Its one of the reasons atrac was developed, but I haven't had any test done meself, the only thing I have isn't nately designed for audio playback (the psp) but I keep hearing it over and over again.

I have always found the sony battery life specs to be accurate, so I do trust them more than other companies and they do show results for most populary used bitrates and batterylife.

I can't find where I read this now, but if its not better its atleast the same batterylife.

I just found this, from the MZ-RH1, but I can't find same bitrate comparison.

(Hi-LP is 64kbps and sounds really good for its bitrate)

They are very rapidly being replaced by things which record onto flash. For example several people I know have junked minidisc recorders for Edirol R1s (http://www.rolandus.com/products/productdetails.aspx?ObjectId=744&ParentId=114) which records in either 24 bit uncompressed WAV or MP3. Although that's a little above the $200 mark.

Fostex and Tascam both make compact flash based recorders but they can't be called low cost.

Just like people say $500 audio cables sound better?  I'm not intersted in what people say, rather I'm intersted in what is true.

Yes but that has nothing to do with ATRAC, and everything to do with the very high battery capacity Sony traditionally uses.

That link says that 64k gets better battery life, and 256k worse, with 128k mp3 almost exactly what we'd expect from 128k or 132k (whichever is used in the latest version of the codec, I forget).  If anything, I think your link disproves ATRAC having better battery life.  Since we don't know if the Sony MP3 decoder is as optimized as their ATRAC3 decoder, we can conclude that ATRAC is no better, with the possibility that it is worse.

Edit:  I'll take that back.  It could be that the Minidisc itself uses so much power that all we're measuring is the bitrate since the CPU power is completely swamped.  In which case format wouldn't really matter.

Or if its use chips to decode, yeah, its a bad example.
