Dune IRULAN.HNM Sound Extraction/Replacement

Recommended Posts

Hi Everyone !,

I’m working hard to extract the sound data from « IRULAN.HNM », it’s the opening cutscene from Dune 1.
I would like to extract and then replace the sound part (English voice) with the french voice.

This format is fully and well documented at :


I found the sound part it’s a .VOC file, id : « Creative Voice File ».

But i can’t found the size of this part in the HMN and i can’t read it with Audacity.

Can you help me a bit only on this file ? It’s for a fan project for abandonware France, we already finished 99% of the translation of each voices.
The only thing missing is the opening cutscenes (the only HNM file who have voices on it).

The opening cutscenes is here :


I hope someone can help us !

Thanks !
