The digital format is really where this problem lies. Your sound card ENCODEs a digital signal in one of the above formats, while the speaker system (or home theatre receiver) at the other end DECODEs that signal. For more detailed information on sound formats, try this thread on the Audio Visual forum.Įncode and Decode: In the context of this thread, these two terms relate to converting sounds to and from a digital signal. Those being PCM, DTS and Dolby Digital (also known as AC3). There are more, but only three digital formats are in mainstream home sound use. That means talking in the same "language", also known as "format" or "standard". Digital is tolerant to interference, but excessive interference will stop the sound entirely, you either get a perfect signal or none at all.ĭigital Formats: When audio is encoded digitally, the equipment at both ends needs to be able to recognise the codes of zeros and ones. Digital overcomes this by encoding the sound into zeros and ones before sending it over the cables, much like the screech of an old modem when you pick up the phone (we don't understand it, but computers can process it). Digital: Analogue sound travels as waves of electricity that are subject to interference from nearby electronic equipment. I won't spend too much time on the fine details, I'll try and sum it up as best as I can.Īnalogue vs.

Well my friend, you've just fallen into possibly the most common trapping of PC digital sound.įirst, a little technical info. have you noticed that you hear sounds from your favourite 3D games in the front speakers only, or you hear the same stereo sounds from all 4, 5, 6 or 7.1 speakers? You've connected it to your fancy speakers or home theatre receiver, but something's not quite right. So you've got a sound card or motherboard with either a coaxial or optical digital-out plug.
