Towtruck Simulator 2015

[AlphaTwentyThree]

Hello!
Despite the title of the game, I'd like to add it to my VGM collection. It uses the insomnia engine and I extracted the files nicely with Luigi's script. However, the audio files use a custom audio header. While I can write a script for PCM 8/16bit, I get a problem with WMA. I've uploaded a sample for each variant and I'd be happy if somebody could provide me with a solution for the WMA streams.
Here are the samples: http://*USE_ANOTHER_FILEHOSTING*/d00baaf ... tts2015.7z
Thanks for your help!

I don't have idea of what should be the format for wma2 in this case.
But I used the same script of pcm with the wma file and probably with some modifications it's possible to open it with mplayer/ffmpeg because it understands that it's wma2 (so the codec field is correct).

Yeah not much useful, anyway this is the simple script I used:

Code: Select all

get CODEC short
get CHANNELS short
get FREQUENCY long
get SAMPLES long
get DUMMY short
get BITS short

savepos OFFSET
get SIZE asize
math SIZE -= OFFSET

get NAME basename
string NAME += ".wav"
callfunction TOWAV 1

Ok, as far as I got.
Can anyone help me with the needed ffmpeg options to decode the file? Any possibility to modify the header to wma so it's playable?
