Dolby Digital digital sound decoding.

Digital audio technology is used in all areas of audio, from casual use of music files of moderate quality to the most demanding professional applications.

The first use of Dolby Digital was to provide digital sound in cinemas from 35mm film prints.

In this case, the card's output channel is irrelevant typically, the card is only capable of two channels of digital sound.

But actually, the most fascinating thing that I found was that even the audio system or wave transmission nowadays are still basically based on the same principle of producing and projecting sound.

USB audio device class support is present from Windows 98 SE onwards.

For years, soundcards had only one or two channels of digital sound (most notably the Sound Blaster series and their compatibles) with the exception of the E MU card family, the Gravis GF 1 and AMD Interwave, which had hardware support for up to 32 independent channels of digital audio.

The custom sound chip on Amiga, named Paula, had four digital sound channels (2 for the left speaker and 2 for the right) with 8 bit resolution (although with patches, 14 15bit was accomplishable at the cost of high CPU usage) for each channel and a 6 bit volume control per channel.

A competing system, dbx, invented by David Blackmer, also found success in professional audio.

They started by highlighting that just like any other economy, there are the two opposing forces that characterise the growth of the digital economy.

The audio subcarrier is further demodulated to provide a raw audio signal.

A key advance in audio fidelity came with the Dolby A noise reduction system, invented by Ray Dolby and introduced into professional recording studios in 1966.

Once the signal is digitized, the PCM signal is usually subjected to further processing (e.g., digital data compression).

The system was awarded one of the International Forum of Digital Content (FICOD) prizes in 2009 for the use of digital content to improve citizen services.
