Thanks! sorry for being a pain, and i used a payday bundle unpacker i found on some japanese site, https://sites.google.com/site/jpmodfiles/localize/payday-the-heist
I knew about the riff headers, i had already unpacked it, but figured it would be quicker to upload the original source file.
HCS: he was running the tool on the same file multiple times, we walked over how he processed the file and he said he ran it twice. i expect since your program modifies the files directly, it changed the codec id. so eventually he was able to "convert" it with ima_rejigger, but unable to play it. i tried using foobar to play one of the .wavs from the OPs file, foobar couldn't handle it. tried decoding it with test.exe and that couldn't either. how are you playing the .wavs on your pc? sox?
Thanks, hcs. Used VLC to play files and found music and other sound effects scattered all over the place. Processed it through the ima_rejigger2.exe, and it works. Example included; it sounds distorted, though.
Now I guess the correct playback and resample rates need to be found, and possibly if it can work in VGMstream, perhaps. I tried using winamp to play them, but only VLC seems to work for the majority of the processed .wavs.
I opened the special .wavs I processed in ima_rejigger, using an audio editor like GoldWave, or etc, to get the correct playback rates, convert them into actual .wav files or .mp3, etc, and make them playable in applications like WinAmp, and others.
GoldWave says the files are in QuickTime Audio, but I'm not sure if that's right. Might be, though.
Music is segmented into parts, like "normal," with a low tempo and "action" sequences, with a high tempo.
Don't know if there's any way to make VGMstream compatible for these special types of .wav files as they are extracted, but would be interested in it.
