Pulse-code modulation (PCM) is a method used to digitally represent analog signals. It is the standard form of digital audio in computers, compact discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled at uniform intervals, and each sample is quantized to the nearest value ...

PCM refers to an algorithm that devices use to represent analog waves. This technology has been around for more than 100 years and remains the standard for transmitting audio streams. Since PCM is an algorithm, it won’t matter whether you’re sending compressed or uncompressed audio files. When a device receives an input, it decodes the data and the...
Bitstream is a binary sequence—or what we often hear as 1’s and 0’s—that we use when converting audio input into digital bits. It’s the technology that PCM and other hi-res audio transmission used as a framework, but it doesn’t make this technology outdated. Although you have fewer options when using bitstream for audio transmission, the sound outp...
Both transmission methods have their advantages and disadvantages, but they don’t make one better than the other. In fact, if you’re going to use PCM and bitstream for the same audio format on the same speakers, the output you’re going to hear will most likely be the same.
Since HDMI is what most players are using nowadays, let’s be forward-thinking and say that you’re, most likely, going to use it for your connection. If you’re going to set your Blu-ray player to use PCM as the audio output, the player will internally decode all the files from Dolby, Dolby TrueHD, DTS, and DTS HD Master Audio codecs, including every...
The process of transmitting files will be different if you’re going to use bitstream as the audio output for a Blu-ray player. The first thing that will happen is that the player bypasses all of its internal DTS and Dolby decoders. The player will simply transmit digital signals to your receiver, which will be responsible for decoding and convertin...
PCM and bitstream may seem very different in terms of the formats that they can produce, but both of these two configurations are capable of delivering high-quality audio. In fact, if you don’t need a secondary audio output or higher resolution codecs, there’s barely any noticeable difference between these two. Whether you’re playing standard or hi...
If you’re only after the audio quality that your speakers can produce, both configurations are excellent. Sadly, setting up your sound system will never be as simple as that. There are dozens of different factors that you need to consider, and, sometimes, you might have to compromise one feature over the other. The quality of the audio file that yo...
Both configurations can produce the same audio quality, convert the audio file to analog before speakers can produce the output, and are compatible with most players that we use today. So, the question is, when will it be better for you to use PCM configuration over bitstream? You should use PCM configuration if: 1. You’re looking for a way to unlo...
Bitstream is the technology that PCM used for its framework, but it doesn’t make it that much better or worse. The choice to use bitstream for your sound system would depend on how you want it to work, and whether various configurations can give you an edge over PCM. Using bitstream for your audio is better if: 1. You want to take advantage of 5.1 ...
There’s no clear winner of the bitstream vs. PCM debate if we’re only going to compare the output that they can produce. The choice depends on how you want to configure your sound system and where you’re planning to use it. If you want a setup that is capable of hi-res secondary audio, PCM is better for you. Both transmission methods can provide yo...
Jun 7, 2024 · Pulse-code Modulation (PCM) is a fundamental concept in audio technology, revolutionizing how we encode, transmit, and store audio signals. It involves converting continuous analog audio into a digital format by taking discrete samples of the signal’s amplitude at regular intervals.
Mar 7, 2024 · PCM (Pulse-Code Modulation) and bitstream are both methods of transmitting audio data – so they’ve got something in common, at least. Dive much deeper, however, and comparing PCM audio vs bitstream can get confusing. In a nutshell, PCM can be considered more “fundamental” than bitstream formats like Dolby Digital or DTS.
Dec 14, 2023 · PCM, or pulse code modulation, is a general term for digital audio formats in which the audio signal is divided into individual samples. If you select PCM, the Playstation decodes the audio material in advance and passes it on to the next device (possibly an AV receiver).
Feb 8, 2024 · PCM is an acronym for Pulse Code Modulation. In this, analogue audio signals are transformed into digital data. This format is used in computers, DVDs and CDs. PCM is beneficial as it can operate and handle both uncompressed and compressed audio formats.

Oct 23, 2023 · What is PCM? PCM (Pulse Code Modulation) signals transmit a sequence of 16 or 24-bit samples, with bits representing a snapshot of amplitude values within a given sample. A PCM signal rapidly plays these still-frame samples to produce the illusion of a fluid and continuous audio signal.
