NBA2K13 - Music Tool - Song Skipping Fix Example

i had some discussions with game modders
i am taking 2-3 days brake from this to clear my mind
i am very near solution but i have to distance to see it clearly

Your avatar in that site

Well i adore cats

So, you are close to find a solution Nesa, try sleep then comeback to the problem.

Helps me, when i'm close to find a solution like you are.

so
69A1BED202000000CD05

isnt just header of section
after 69A1BED2
02 part must point to stereo
44AC after CD05 part must point to 44100 rate
and its ADPCM

So we are missing only two things
1. BitRate
2. Version of ADPCM ( Microsoft or Intel one )

Will try later to figure it out

Holy cow. I have no clue what on earth all of this Hex stuff you're talking about is, but this is the biggest progression in this department that we've seen since 2k has graced the pc. If you can figure this out, then

good job man

Please nesa release something
Alredy got a sountrack!!
)

nope
failed to get it right
we need help from xentax guys

adpcm is used on many xbox ported games (halo,psychonauts..)

You have alredy make some help request?

good news so... ^_^

You have alredy make some help request?

no i cant post there
cant make account

so as its ADPCM its 4bit big-endian with chunks for every song
every chunk/section has a number that is at offset 24 with it of an chunk

First Song in file ( Mercy ) ends at CC570 offset and that song has 56 parts.

Hopefully we do get some help

good
i have asked on audacity forum

btw who is Pdub and where can i contact him? ( regarding your post with his quote )

no need for ONLY thing mate
i am new here so its normal to ask rather than search around

Well today is my birthday so no more from me in next 2-3 days

nothing useful can come from posting it on OS the people who would see it there have seen it here, and you can create an account there without donating, I know that for a fact.

yea but i cant make new topic for 7 days due to limits

We would like to inform you that your posting privileges will be limited to begin (you can not start any new threads OR send any private messages) for 7 days.

Thats why i asked
Just trying to get whole community (NBA+PES) in this to solve it faster

damn, when did all these sites implement these restrictions?

According to the offsets you listed, if you strip the chunk headers from Mercy, you end up with a song that is around 800-900 kb large. It has to be compressed. Even the lower quality adpcm encoding puts the song in the 4 mb range, while sounding like crap in comparison to the 2K version. The song is about 3:30 long, and that would put it at 4 KB/s for 2K13. That means that the bitrate is around 32 kbps. If it's compressed at say a 4:1 ratio inside the container, then it could be 128 kbps. These are all approximations that I made after recording the song and encoding it to the adpcm codecs. I still think it could be xma adpcm, or just adpcm compressed with zlib. If you look at some of the cdf audio files, they have ZLIB headers, which means they are compressed. If it was uncompressed, even with chunks you could align it by it's encoded blocks inside a hex editor, but that doesn't even work.

well no freedom no community and devs for community
restrictions is main problem in 2K comm

with what did you encode (audacity/vdub..)
ADPCM is bad format but memory points to it and its common used on XBOX ports so it must be it
It can be that ADPCM is used only in video files of game but i dont think that

840KB is 1st song
1095KB is 2nd song
615KB is 3rd song
http://www.mediafire.com/?t1o89c7g0280tr4 <<< Song separated 1-2-3 ( from start of jukeboxmusic.bin )

As of zlib i dont think its zlibbed
Dont have proof but dont think its

omg

so noone pointed me that leftos did some research with this
viewtopic.php?f=141&t=87230
http://forum.audacityteam.org/viewtopic ... 28&t=67117

its can be au since au has ADPCM
hope that leftos can help

Hell, Leftos works with 2K now, think he could give some insight into this?
