tl;dr (essentials)

1. Audio files for Spectacle should be formatted as .ogg files.
2. Audio files should have names 00.ogg, 01.ogg, 02.ogg, etc.
3. The audio jack on the Audio Board produces output suitable for 

amplification only. 

It is not suited to headphones or unpowered 

speakers.

Meet the Spectacle Audio Board

Designed to be a low-cost and easy to use method of adding sound to 
projects, the Spectacle Audio Board integrates with the rest of the 
Spectacle ecosystem to provide sound effects on demand.

It has three 1/8" (3.5mm) jacks: two for Spectacle control signals and one 
for the audio output. 

Be certain you are plugging cables into the right 

jacks!

Plugging an audio device into one of the Spectacle jacks could 

cause damage to the audio device. Note that the Spectacle data jacks are 
directional: the one marked “In” should be plugged into the “upstream” 
board (i.e., closer to the Director Board than this one) and the one marked 
“Out” connects to the next downstream board. 

The “Out” jack is not for 

audio signals.

The audio output is designed for amplified devices only. This means that 
any attempt to use the Spectacle Audio Board with headphones or 
unamplified speakers will fail to produce audible output. SparkFun sells a 
small, amplified, rechargeable speaker which is specifically intended for use 
with the Spectacle Audio Board.
