What is the difference between PCM and Dolby?
The PCM audio recorded on DVD is a two-channel digital, stereo audio track. The Dolby Digital® technology, which was originally called AC3, was developed specifically for multi-channel applications, including film sound and digital surround sound in the home. Dolby Digital® technology uses a 5.1 or six channel format.
Is PCM good sound?
PCM is generally a high-quality stereo (2 channel) format. This would be appropriate to send to most soundbars which are also stereo playback devices. If your soundbar supports surround or virtual surround, you should be sending a digital surround format that it is able to decode.
Should I use PCM or Dolby Digital?
Distinguished Member. Dolby Digital is compressed so PCM is better. Dolby True HD, DTS HD MA, Atmos and DTS X are also lossless, so should be similar quality to PCM. If the source audio is stereo, it should only be coming from your front left and right speakers unless you use an up mixer.
Which audio connection is best?
Both HDMI and optical digital audio from one device to another are better than analog that can pass multi-channel audio. Both of these cables had pretty cheap. However, the simplest advice is to go with HDMI. The biggest difference is that HDMI can pass the higher resolution audio such as formats found on Blu-ray.
