@BadFurDay Sort of...

I tried compressing to mp3 with scummvm_tools and it does play, but the quality is terrible (not only in lr-scummvm, but everywhere). I guess the format is slightly different and scummvm_tools isn't completely compatible. [EDIT: But I only tried once. Might be worth trying to compile scummvm tools from source or try on a different system...]

It seems that Talkie Builders can't create mp3 version directly (but maybe I overlooked something).

EDIT EDIT: Talkie builders can create mp3 versions and they work and sound great.
