Hello!
Little feature request: add an option to set the frequency of the sounds. I think the birds sounds from DynamicSurroundings for example are too rare, I love them.
I would love to see the birds sounds from the old mAtmos return they were so beautiful.
Lastly, I don't hear any wind sound in the forests (like in the old mAtmos), it would be nice to have those to improve immersion.

The vast majority of the sounds in the mod are live recordings from various places around the world. The Forest tracks do have a little bit of wind, but nothing that stands out as wind. In biomes with the HILL attribute get additional wind - I think Minecraft's Birch Forest falls into this category.

Bird sounds and the like are considered "spot sounds" - sounds that have a chance of playing based on the player's current biome. For example, the Loon can only be heard in biomes similar to Taiga, and the Raptors (bald eagle and red tailed hawk) won't be heard in swamps.
