Pcm audio, which is also called “pulse modulation,” is a way to turn analog signals that have been sampled into digital ones. It is the standard digital audio format for computers, CDs, digital phones, and other digital audio uses. In a PCM stream, the amplitude of the analog signal is sampled at regular, even intervals, and each sample is quantized to the nearest value in a range of digital steps.
Does PCM Audio gives surround sound?
PCM can send surround sound, but it can’t do so over an optical cable. Only stereo PCM can go through the optical cable (using TOSLINK, the home stereo standard). To send a surround PCM, you must use a cable that carries both the video and audio signals, like an HDMI cable or a PC’s display connection.
The surround can be “bitstreamed,” which means that the signal as it was originally encoded is sent over the cable instead of first being decoded into a PCM signal. As long as the device you’re sending it to (in this case, the soundbar) can decode it, there shouldn’t be any problems or quality loss. I can’t say for sure, but I think that most of the surround content you get from a Smart TV source is Dolby Digital, which should be supported by any soundbar with an optical input. If you are using HDMI, the decoded PCM signal or bitstream can be sent to the source if the soundbar supports it. But if you choose the first option, you can avoid problems with compatibility.
PCM audio in TV
With the TV’s PCM audio feature, an analog signal can be turned into a digital signal. In the PCM process, the signal is sampled at regular times so that the bit depth can be measured before the signal is turned into binary code.
PCM or Bitstream? Which is best for receiver setup?
The bit stream to the receiver means that the information is sent directly to the receiver without being encoded. The information is then decoded by the receiver.
PCM to Receiver means that your source decodes the information to PCM and sends it to the Receiver.
If you want to decode everything from the receiver, you should use bitstream.
Some 10 year old receivers can’t handle new audio formats like dolby truehd or dts hd, but they can handle PCM. In this situation, pcm is the best and only choice.
Bitstream is better, but it doesn’t make much difference for stereo sources, unless your pcm decoding isn’t very good. Bitstream is always better when it comes to new audio formats.
You can choose pcm or bitstream on this bitstream until 5.1 sound.
In direct mode, nothing changes. You get the signal as it is, whether it’s stereo or 5.1 or something else.
Is Bitstream better than PCM?
Most of the time, no, and you can’t tell the difference in sound quality between the two. Most modern audio devices with DACs (digital-to-analog converters) are able to make high quality sound. So give it some thought to see if you should instead let your Blu-ray player decode digital tracks. It doesn’t matter who your sender is. I know there are a lot of high-end DACs on the market, and some audiophiles will say they can hear a difference or at least say that DAC A sounds so much better than DAC B in reviews, but there’s no way to tell if they’re just lying or if they can actually tell the difference.
PCM is better than bitstream when you want to hear the extra sounds in movies, like audio commentary tracks, sound effects when you move through the main menu options, and so on. Almost certainly, when you do an ABX comparison, you won’t be able to tell the difference between the two.
PCM or Dolby Digital better with a soundbar?
At most, you get stereo sound when you listen to PCM. You need Dolby Digital, DTS, etc. to get surround sound.
A lot of people say that PCM sounds better than Dolby. Since I’ve worked with both professionally since the beginning of home theater audio, I don’t really see a difference.
Technically, the PCM is better, but the sound is what I care about.
Does PCM support multichannel audio?
PCM is the name of a file type that most people call.wav (Windows Audio). It will only work on a Windows computer. It carries both the right and left stereo channels. If you can hook up your Windows PC to the Dolby 5.1 amplifier, the sound should be better.
