Gran Turismo 4 *.VOL

Post by Mygoshi »

Hello,

I wanted to extract the sounds from the GT4.VOL archive, but there's no script ATM.

Here's the link to it: (expired)

Thanks!

GT3FSExtract.
On every forum online there are people who had success extracting gt4.vol with the gt3 extractor.

Thanks! I used this and it extracted ADS files. I'm going to check if I can do something with them.

I think the ADS file I uploaded is not an audio file. Right?

I think this tool was made for GT3, probably the extracted files are corrupted.

I thought about simply recording the music while I play the game. But it has nothing to do with this format's research.

In certain situations the lame recording of the music is not a bad solution.
Yes it takes more effort but in terms of quality is the same of ripping them, if you planned to convert VAG to mp3 obviously.

I still think using the files remains the best solution.

I'm trying to get info about how can I record the music in the highest quality possible in the most accurate way.

Certainly not! An internal "what you hear" recording records the ANALOGUE output signal directly before the chinch. That's about the same as looping a cable to the mic input and recording it. As far as I know the only possibility to record truly lossless audio is by looping a SPDIF cable from the output to the input. So you'd need an additional sound card with an SPDIF in.

I'm not sure if "what you hear" is the analogue output.
It should be handled just at driver level by forking the raw pcm data meant to be sent to the output.

There is not much documentation about these virtual devices ("What you hear", "Stereo mix" and so on) so let me know if you have some links.

I think I found more interesting files about music, so I'm gonna share them.

Link: (expired)

Could something be done thanks to this? Thanks.

The recording solution is slowly becoming necessary...

Why not rip the music from YouTube?

Use Chrome or Firefox and find a plugin that lets you download a YouTube video as an mp3 file.

Well yes, that's the idea behind the concept but "what you hear" is literal in this case - just the raw analogue output. You can check it by recording "silence" and then normalizing the recording. You'll see that there's (analogue) background noise.
I was sceptical some years ago when I downloaded a rip where you could hear that somebody recorded a mono output as stereo. When I did an inversed overlay of the channels, the result was all but silence. ;)

@Teancum: Do you really think my approach is simply taking the music from YouTube and convert it to MP3? First of all the source is already low quality, and convert it again to MP3 128kbps will not help.
