Lets free up the other thread(s).



Have at it guys, lets open this Z1 up!

These are Compressed audio files in sonys minidisk format.

Are you able to play them in anything? I'm concerned they are encrypted in some way.

someone with a non xp sp2 machine download the liquid audio plugin for winamp. just do a search under plugins for liquid audio

install it then go to plugins, under input select it and hit configure and get a passport to play on this machine only.

then see if these at3's will play with that.

Ok, I grabbed one and set it to image with XP - no service pack. Should take 30 min.

No go with the Winamp and plugin.

also tried to convert the Atrac to wav and mp3 with no luck. Tool can be found here: http://marcnetsystem.co.uk/cgi-bin/mn2.pl?ti=1149883039?drs=,V83M0R564,39,2,

this is a pain in the ass isnt it.

wtf did they go with atrac format.

i mean if the quality it still gonna blow and we cant run mp3s or high bit rate atracs then i think i'd just rather play the music off a dvd data disc ripped with mp3s using roxio method no?


as long as searching thru music is still as easy as it would be as searching on the disc i dont really care.

i can fit my entire collection on a dual layer dvd.

man i need to get my hand on one of these z1's soon so i can contribute more and figure this thing out.

Well, cracking the main operating system will allow us to get into adding another media player or something. That will help with the quality issue.

I found out why these Atrac file suck.

From another board:
you gotta understand that ATRAC basec codecs are designed to only be played back on Sony headphones.

Explains everything. lol

There are 3 of these .AT3 located an ftp site:

BigFloppy,

I can't log in to the FTP server using that account and password--is it still up? I have some audio apps that I'd like to try opening those files with...

Looks like someone is downloading the files right now... shouldn't be any problems

BigFloppy,

I can't log in to the FTP server using that account and password--is it still up? I have some audio apps that I'd like to try opening those files with...

Doh! Nevermind, it was an Internet Explorer issue--I ftp'd in from the DOS prompt and it worked fine...

OK, I tried reading the files in every audio application at my disposal, including Sony's own Vegas and Sound Forge, and nothing could read them. I had high hopes for ACID Pro 6, which is advertised as being able to read ATRAC files (with .aa3 and .oma extensions), but even that didn't work. I did try simply renaming the AT3 files to extensions that ACID Pro supports, but it still didn't know what to do with them.

I'm wondering if they must use some kind of encryption, in addition to compression, to make sure these files can't be copied, and that audio files can't simply be written to the disk from a computer. If that's the case, they could use the unit's serial number in the encryption; this can be tested by moving a hard drive from one AVIC-Z1 to another, and seeing if the music is still accessible. Has anyone been brave enough to try that yet?

Go grab them! Lets try and see what they are... are they real PSP audio files OR just a renamed other type of audio file. We know (almost for certain) they're compressed audio files.

Have at it guys, lets open this Z1 up!

Did you shut down the site? I'd like to download one of the files to play with.

Site is still up... DO NOT USE EXPLORER TO GET THERE

Use an ftp program

hehe oops.....reading helps. ;)

Have you tried creating an at3 and putting it on the Z1?
http://www.gamersreports.com/forum/inde ... entry14057

or is there a mess of DB files that need to be edited with it?

I did not try adding an AT3 to the Z1 yet.

As far as DB's yes, there are several files that get created/modified.

I should have uploaded it here instead of the other thread since it's AT3 related. Here is the link to the files modded when an CD is ripped to the Z1: http://www.avic411.com/forum/download.php?id=215

What I will try (once I have a successfully created and tested AT3 on my PC) is replacing one of the existing tracks with the alternate AT3 file. As you can see in the attachment the final at3 is just named Track0x.at3. Nothing to do with the song/album/title. All of that is in the other files.

i have tried just about everything trying to play those at3 files, opened it with all types of files types in a special audio editor program. tried in a md player, ipod converion programs, psp conversion programs. even tried flipping the audio track and converting it. wiles wont play in a d1 either. good job pioneer!

Perhaps the headers are not stripped from the files but something has been added.

I ripped the first track from the offspring CD using goldwave and the AT3 codec from Sony and at 132bit the ripped track is 420,592bytes and the same track ripped by the Z1 is 463,880bytes.

You already have the Z1 ripped file in this thread here: http://www.avic411.com/forum/download.php?id=215

Attached to this post is the same track ripped by Goldwave.

I added the track to the Z1 HDD and loaded it back in the Z1. The new file didn't play. What I did notice was the track before the one I loaded no longer played either. Here is what it does:

Track 13 was replaced with the converted Atrac3 track.

Track 11 played fine.
Track 12 lit up on the display like it was going to play for about 1/2 a second
It moved to track 13 which did the same thing for 1/2 a second
Then Track 14 lit up and began to play normally.

It apparently does something with reading ahead or linking the tracks together since I didn't do anything to track12.

I think I'll create a CD with a single track and see what it creates.

Ok...first thing I need to say is for the most part, you guys are WAAAAY over my head with your abilities...so please keep that in mind before you roast my butt!! LOL

My first question is...aren't you saying that if you load mp3's onto a DVD or CD the Z1 will play them? If so, isn't there software already on the Z1 you can utilize? Maybe some sort of path needs to be written in that software to direct it to the hard drive instead of the disc.

Next question...doesn't an ipod play mp3's? (seriously...I have never owned one and I don't know for sure...but I swear my son told me that's what his uses) If so...and you can get an ipod adapter for the Z1, wouldn't it be easier to just add some sort of hard drive and run it through the ipod adapter? I realize it would take more than just a hard drive, but would it take that much more? You could figure out a way to easily remove it or use a laptop, etc to load it, etc.

Please...I know I'm pretty clueless about what you're trying to do here...so please go easy on me. I see the benefits of being able to work with the factory drive compared to adding one...but if that won't work...maybe something like this would.

Awsome work Pulp!

I like your idea of doing a one track CD. I would also make two CD's with, say, five tracks on them. Make all of the tracks the same except the third track. You need to do this on a "fresh" disk each time so you can compare the files to see if the track two song does in fact change.

You know I would also rip the exact same CD twice and compare the files. Some encryption methods use the time or a "random" number as a modifier to the encryption key. If they do that then the two idental disks will have different files. This will give us some info on the encryption (if any) being used.



Oh, what bitrate did you save the song as using your PC? 132kbps?

Ok, I've gotten a Z1 AT3 files to play on the PC. I basically just plopped the data from the Z1 file into the data portion of an AT3 file made on a PC.

WinAmp wouldn't play it and GoldWave wasn't happy about it because I didn't modify the PC file's header to have the correct length but it still loaded and played in GoldWave. Now I'll figure out the format for the PC AT3 header and fix it so the length is correct.


This means I should be able to easily "convert" files made on the PC to the format used on the Z1. The problem being I need to figure out where the headers are being stored and the database structure for that.

I'm including the hacked Z1 to PC At3 file here just because I know people will want to check it out. Remember it only works in GoldWave for now, I'll fix it and upload the fixed version too.



Oh! Duh! The great news about this is that the files are not encrypted!
