I am sorry to write in English. It is easier, but if there's a problem, I can go back to my broken Italian.
Now, you need to launch the sub-mod with the Iron Launcher provided. The original Mount and Blade didn't support custom fonts by default.
Well, with the Module System everything is easier and possible. Finishing the quests are a priority, but I would like to do more for this great mod.
I use this, along other techniques:
Decrease the volume of big spikes in your audio. To decrease the volume of an audio selection in Audacity, click ‘Effects’ from the top menu, then select ‘Amplify’ and choose a db value (generally we choose around -2db to reduce the volume of a section).
It's just one of the ways to do it. You can make the whole track, not just one part of it.
