[SOLVED] Xbox ADPCM mono

Post by AlphaTwentyThree »

Hello!
I have a bunch of Xbox ADPCM mono files here with a 0x4c header. I can create playable files but strangely they only play halfway through and cut off.
I've attached some samples of source files and transformed ones.
Does anyone know where the problem lies? It sounds to me as if only half of the samples are actually played.

I've added a GENH header and they play exactly the same as your .wav files. They're all about 2-3 seconds long, so it looks like that's all the data there is.

(From some Harry Potter game?)

Alright, thanks for checking. Yeah, from Harry Potter and the Sorcerer's Stone.
