Problem with Duke Nukem 2 IMF files

[Gothic]

When I play these archives on zdoom, they sound really fast. Does anybody know how can I fix this?

[edward850]

IMF's have no defined tempo, so there's only one tempo ZDoom can actually play them back at.

[Nevander]

Does that mean the engine is what decides the tempo? So the Duke Nukem 2 engine plays them right but ZDoom just plays them with a set tempo?

[edward850]

Yes. Specifically ZDoom plays them back at Wolfenstein 3D's rate, 700 tps.

I have an idea to fix this, I might work on it later.

I guess this doesn't have a solution then. I tried to convert the .imf files to .mid and back to .imf, but I had some problems with some audio converters (I only got blank midis)

Try to use Camoto, apparently it should be able to convert IMF to a different Adlib format like DRO. Alternatively, IMF crusher is advertised as being able to convert to a different update rate.

Thanks, Camoto worked perfectly.
