SO mainly the PSP game audio format is AT3, but sometimes when i extract the music files from the UMD archive, i get a WAV file. So i assume that its disguised as a Wav file and i rename it to AT3 and use H-MI rendered to convert it and it has worked successfully for other games but it won't convert now even with sonicstage installed.

Can anyone help?

Here is one of the sound files.
