What is passthrough audio?
5.1 audio passthrough allows you to connect a source device to a TV and have the TV pass the source’s surround sound signal through to a receiver or soundbar.
It can help cut down on the number of cables necessary for a surround sound setup, and without much impact on sound quality..
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.
What is HDMI ARC?
HDMI ARC is designed to reduce the number of cables between your TV and an external Home Theatre System or Soundbar. The audio signal is capable of traveling both ways to and from the speakers, which will improve the sound quality and latency of the signal.
What is PCM audio on TV?
PCM: This stands for “pulse-code modulation.” Use this setting if the external device you’ve connected to the HDMI port has already processed the sound, and you just want it to come out of your TV’s speakers.
Which is better 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.
What’s better Dolby or DTS?
Dolby Digital compresses 5.1 digital audio down to a bit rate of 640 kbits/s (kilobits per second) for Blu-ray discs. For DVD discs, it supports a slightly lower bit rate: up to 448 kbits/s. DTS on the other hand, is less compressed and supports higher bit rates of up to 1.5Mb/s (megabits per second).
What is PCM sound?
PCM (pulse code modulation) describes a process that’s used to convert analog audio signals (represented by waveforms) into digital audio signals (represented by ones and zeros — much like computer data) with no compression.
Is PCM Dolby Digital?
Pulse-Code Modulation (PCM) and the Dolby Digital® technology refer to different types of digital audio recordings. PCM is the conventional method for converting analog audio into digital audio. … Dolby Digital® technology uses a 5.1 or six channel format.
What is digital audio output?
The optical jack is designed to output sound when the video you’re watching contains digital audio (PCM or Dolby Digital® technology). This feature is available on certain digital broadcasts and streaming video, and isn’t supported on standard cable or analog stations.
What does RAW mean on TV audio?
bitstreamOriginally Posted by Ratman. Raw is for ‘bitstream’. It will pass DD, DTS or PCM stereo. PCM is for PCM stereo only. So it should be set to RAW.
What is the difference between PCM and raw audio?
The only difference between PCM and RAW audio output is self-decoding and non-decoding. RAW supports source code output, and PCM can decode and play by itself.
