audio signals
Sound wave transmissions
Audio signals are electrical representations of sound, carrying information as variations in voltage or current that correspond to acoustic waves.
In audio engineering, these signals travel through cables, circuits, and processors before conversion back to audible sound through speakers or headphones.
Digital audio signals encode this information as numerical data: The audio signal was too weak and needed amplification.
The term appears in technical contexts discussing recording, broadcasting, and sound reproduction.
