will, the souds are all stored in the maps themselves, such as a.10....To do this, you would have to get hmt and open the map and then find the sounds...
The sounds for HaloPC are stored in sounds.map, you'll still need to open the specific map in HMT in order to extract them. However, depending on the sounds you want to extract, you can open any map. Alot of sounds are used in every map.
