Is anyone able to help with file format?

From a Hex editor

Looks like DSP

Tried renaming to adpcm for fun.. and playsbut lots of static as well so guess coefficients are required to get working


Coef are here right?


Sadly, Not my area of expertise so not sure how to implement to actual coef into a dsp file.

Can anybody help me with the coefficients then? It would be really helpful.

Does anyone know about coefficients that could help me?

DSP? I'll look at it over the weekend.

I just glanced at that file and found coeffs at 0x7e and 0xde. I'll verify with vgmtoolbox when I'm home, but I may be able to add this to vgmstream. Do you have any more sample files with either more channels or less channels?

I definitely have some more samples, but i don't know if they have any different channels.

I could provide more files by PABLEXWorld at 9:26 PM EST on January 21, 2016

I have a full rip of Just Dance 2016 for the original Wii (headers are RAKI....Wii adpc..."...@........fmt ...P....dspL...b...`dspR...Â...`datS...@.) Will it help? If so I'll post as many files to a MEGA folder as you tell me could be necessary.

I have the wii u versions converted through VGMToolbox. I don't know how to implement a new type of audio into vgmstream though. And i also have all the Just dance games extracted so there is no need to send more samples.

by PABLEXWorld at 7:38 PM EST on January 28, 2016

Allright. I'll try VGMToolbox to convert mine. Do I need to know anything special to get them decoded? [PS: Really tried, but couldn't do anything, don't know how to use VGMToolbox at all, Google didn't help, could someone take the time to teach me to rip these things, if possible? I know how to use VGMStream or FFMPEG, and I can perfectly use a command prompt, it's just that UI that confuses me, so if I can't use VGMToolbox to extract that sound, you could tell me to use other tool, I also want these converted to WAV.]
