While playing with this mod, it doesn't seem like there's any biome ambience or very little. Outside of maybe birds and quiet wind it's utterly silent which is off putting when I try to download the mod for more sounds. They need to increase their frequency and volume because I'm primarily using this mod to get rid of minecraft's eerie silence.
