Native audio formats used by DOTT

Hiya,

 

I working on an Amiga port of DOTT and need to know the audio formats for speech/fx and music.

 

It appears that the music is stored in TENTACLE.001 in (I assume) MIDI format?

 

And the speech/SFX is stored in MONSTER.SOU, no idea of the format though.

 

THanx :)

 

Update:

 

I think it may be in RAW PCM format which is apparently a WAV file without the header info. I haven't actually managed to load any of my ripped PCM files yet though?

 

Update x2:

 

Ok looks like it's 'Raw PCM signed 16bit, little endian, 5500 Hz, 88 kbps, mono' (which is very low). I think this file might be off the PC floppy version though...hopefully the PC CDROM version is a bit better!

Music is in format 2 MIDI. Check the engines/scumm/imuse directory of the ScummVM source code for how to interpret the imuse specific commands. The monster.sou file should contain a bunch of VOC files. I believe Scummrev over at Lucashacks (Mojo hosted site) can extract them.

It is VOC, mostly 22050 Hz, 8 bit, mono, but there are also a few 11025 Hz files. The floppy version is 11025 Hz throughout.

 

And there actually is an old ScummVM version for Amiga OS3 which can run DOTT. The Adlib-Emulation might be slow on weaker machines, though.

Hiya,

 

Ok thanks for the info :)

 

Yep this port is based on one of those other Amiga OS3 ports. I'm just trying to improve the sound quality and program performance.

If I can't get my Amiga MUS player working (see my other thread) I might have to use the Midi to Adlib driver to create digital sound instead. What kind of quality of digital samples does the Adlib driver create...anyone know?

 

Eg 22050 Hz, 8 bit, mono?

Can I bump an old thread, got the audio working ok now :rolleyes:

 

 

(This BBCode requires its accompanying plugin to work properly.)
