The game in question is Captain Tsubasa Ougon Sedai No Chousen, a football RPG for the Gamecube released by Konami. I managed to extract these .dat files from the game's str.pac file somehow but I believe these .dat files contain the audio data from the game. I've tried to extract or play it using different ways but couldn't manage to get anywhere. I did try to import the raw data via Audacity and I can hear some of the audio but there's a lot of loud static noise on top which makes it inaudible. If someone can help me with how to extract or play the audio files, that would be amazing.

Here's a sample of one of the .dat files in question. Maybe somebody can have a look at it?

Here's TXTH script to play your sample
You need a vgmstream's commandline tool/media player plugin to use this script below

Code:

channels = @0x04:BE
num_samples = @0x20:BE
sample_rate = @0x28:BE

codec = DSP
start_offset = 0xe0
coef_offset = 0x3c
coef_spacing = 0x20
coef_endianness = BE

Save the script above as ".dat.txth" and put it in the same directory as the dat files you've just extracted.

Note for foobar components: By default, it won't play any files with unsupported extension, so you must enable these options in the preference to making it work:

OMG. You are a legend! It's working! I can't thank you enough as to how much I've been wanting to extract this game's audio. You have my thanks x 1000!

I'm very thankful for you to help me with this, and pretty much 90% of the dat files I'm able to play. But there's a couple of them which I'm unable to using your method. Would you be able to look into it and let me know what's the issue with these ones?

One of the files in question is this one: https://www.mediafire.com/file/5kyxdtbw ... 1.dat/file

Once again, very grateful for your help.

Uh oh, I think I might have hit a roadblock here. You see, the format doesn't have offset/size fields for each sounds, only start-end sample ranges (Sort of like cue sheets for BIN/CUE files). And due to the limitation (or rather, unimplemented stuff) of the TXTH script, looks like the extraction might be impossible for now unless vgmstream implements something like sample_start/sample_end variable.

Ah I see. Well, many thanks for your amazing help still. Because of you, I've managed to play about 95% of the sound files! That is more than enough to be very happy about!
