Ambience

Ambience is (occasionally quiet) sound effects with the purpose to fit the background, atmosphere, mood or simply to add suspense.

Random Ambience
Random ambience is the successor to the prior ambience system. In Baldi's Basics Plus, the system waits a random amount of time from 90 to 300 seconds, selects a random chunk to play the sound effect, and then waits another 90 to 300 seconds to start the process all over again. In Classic/Birthday Bash, they are "pathfinding ambiences" that can be heard on occasions play from the pathfinding code. When a character finds a new location to walk to, there is a 1 in 49 chance (roughly 2% chance) that a random sound will play.

The Test's Ambience
The Test's ambience is a noise made by The Test while the player is looking at him or during the "blind" effect.

Crickets
Crickets is an outdoor background noise consisting of cricket chirps where is heard during the camping field trip. Prior to Baldi's Basics Plus V0.3, the sound's speed would decrease each time when the campfire gets dimmer.

Cafe Ambience
Cafe ambience is heard inside the cafeteria, mainly in the center of this location. The strange ambient itself is extremely quiet, and if the volume is turned up high enough, one can hear the sound of the quiet radio static along with something like sounds from children in an elementary school class. If the silent parts were to be normalized, it can be heard that the part of the sound was put in silence.

Glambience
Glambience plays during the ending section of Baldi's Basics Birthday Bash in the glitched school. This ambience is filled with glitchy static and plays very quick ruler slapping sounds out of occasional sudden.

Trivia

 * General
 * The "creepy sound" audio, which sounds like heavy breathing, was actually recorded around 2009. This was revealed by mystman12 in his stream.
 * The cafe ambience was recorded years before mystman12 started the development for Baldi's Basics Classic, however, the audio's origin is unconfirmed.


 * Baldi's Basics Plus
 * Prior to V0.3.3, there were no random ambiences.


 * Classic/Birthday Bash
 * The pathfinding ambiences have slightly higher quality to the sound effect, and have proper names for the file instead. Plus, the ambient sound effects do not sound noticeably more distorted like in Baldi's Basics Plus.


 * Baldi's Basics Birthday Bash
 * Glambience's name is likely a portmanteau name of "glitch" and "ambience".
