Audio is a series of sound clips saved as
.wav files and one of the most important features to use for the Baldi's Basics series.
There are also voice clips heard out of nowhere. The disembodied voice will play when counting down to 10 for the test procedure event, and telling the player to run while Baldi is eating An Apple, although the voice is almost inaudible.

Music is mainly used to add tone and atmosphere to an otherwise quiet world. Most music was composed by Cady McGonigal.
- Main article: Ambience
The purpose of ambience is similar to music as they both add tone and atmosphere to the game. However, ambience is made up of sounds and other noises whilst music is composed of musical notes.
In the game files, sounds that attract Baldi have a specific noise value. The values range from 0 to 127.
Here is the list of audio with the noise value in ascending order:
|Standard doors and swinging doors opening||Less than 31|
|Elevator gate closing||31|
|Arts and Crafters' teleporting||64|
|1st Prize's slam effect|
|Blue locker opening/closing||78|
|Principal of the Thing's detention||95|
|Alarm Clock's ringing||112|
|Buzzing noise from Baldi's Math Machine||126|
|Mrs. Pomp's screaming|
|Baldi sees the player||127|
There is also a sound that attracted Baldi when it played, but it no longer happens in the current version:
|Camping field trip when the campfire dies out||127||V0.3|
If the newer noise has the same or higher value than the previous one, then it will overwrite the previous sound. For example, if Mrs. Pomp screams at the player for being late at her class while Baldi heads to the Principal's office due to detention, then he will change the direction to the center of her classroom, unless he sees them while heading to her classroom.
