Does FMod’s bank quality map directly to the ogg encoding quality? As in 60% FMod = q6 Ogg ~= 192kb/s target rate?
Your assumption is almost correct. The ‘q’ argument of oggenc ranges from [-1, 10] and the FMOD bank quality ranges [0, 100] so the formula is ogg_quality = (fmod_quality * (11/100)) - 1
