I wish you all a Happy Christmas season!
Content updates for this mod will resume in January 2023. The Winter sounds mod will get an update this month though, so stay tuned for that. 
Please note I will keep an eye if the mod needs any compatibility updates through December - it's just content updates that are on pause.
The v22.99 update notably introduces custom default variations of air cutoff sounds for when the air compressor is unloaded by the governor, improvements to the implementation of the new 1.46 insect, bird, and traffic ambient sounds (which quite a few have made feedback about), and many other changes.
This year is also the second year in a row with 99 content updates and a highly frequent update schedule. It's really nice to see the progress made so far, especially on the goal for completing the modification of the base game AI traffic sounds.
At the end of 2020, we had 2% of the base game traffic sounds modded.
At the end of 2021, we had 10% of the base game traffic sounds modded.
At the end of 2022, we now have 38% of the base game traffic sounds modded.
The progress has went faster and faster each year. A lot of the remaining % of base game traffic cars are police cars, which I may be able to reuse sounds for from the civilian variants of those, so I imagine we will see an even bigger jump in 2023.
If you haven't noticed already, the reefer sound addons (part of the Sound Fixes Pack Collection) have been updated to 1.46. Special thanks to LucaYT for the video showcase and tutorial.
Without further ado, here is the mod update!
Pack updated to v22.99 with the following changes:
7 additional default variations of air cutoff sounds for when the air compressor is unloaded by the governor.
It adds to the 3 air cutoff sounds already existing in the base game.
Improved foreground layer of daytime bird chirping ambient sound effects.
- Bird sound position moved away from the truck to prevent hearing it too often with windows closed.
- Chirp frequency peaks at 4 AM in the morning.
- House sparrow (a common wild bird) bird chirp sound effects now also included.
The 1.46 city ambient sound event of vehicles passing would feel strange when no traffic is around:
- So this has now been modified to a much more distant traffic sound.
- The former sound effects might get merged into the Sound Fixes Pack AI traffic sounds in 2023. We'll see!
