DSP file format specification (need header) by valiant at 4:15 PM EDT on September 13, 2006
Hey there! Could someone please inform me about the DSP file format? I need the header for the dual-file stereo format because I want to extract files from the demo.dat archive in "Metal Gear Solid: The Twin Snakes". I'll have to do this manually with a hex editor because I don't think there's an extractor for the dual-file DSPs yet. So could you please give me the header data? Thanks in advance. :)
Did some research. All of the cutscene audio's dialogue is hard-encoded into the music files in OGG format. The files are packed in movie.dat/demo.dat/vox.dat. Unfortunately I was just able to extract a few of them manually and there are playback issue - there is no distortion but every two or so seconds, half a second of the file is missing.
Nova Software Extractor splits the OGG files into thousand single OGG/OGM files so this is not an option either. Since it's not possible to rip the cutscene audio without dialogue a line-in rip seems most plausible.
