Digital Audio Concepts and Applications

The video tutorial by Rick from the O-Ray team explains digital audio, its history, and how it compares to analog audio. It covers the terminology and interfaces used in digital audio, such as SPIDF and Toslink, and demonstrates how to convert digital audio to analog for compatibility with older equipment. The tutorial aims to simplify the understanding of digital audio connections and standards.

What is one of the main reasons digital audio can be confusing?

What is a common feature of coaxial cables used for digital audio?

• They have poor shielding.

• They have gold contacts and good shielding.

• They are typically blue.

• They are only used for video signals.

What is the purpose of a digital to analog converter?

• To convert digital audio signals to analog signals

• To enhance the quality of digital audio

• To connect digital devices to digital amplifiers

• To convert video signals to audio
