You will not notice the difference. Furthermore, if you want to switch between Bitstream and PCM , there are lots of players that facilitate it. AVRs work similarly and are compatible with both. However, the major similarity between them is they need to convert audio files into analog for your speakers to play them. PCM and Bitstream perform many of the same duties, such as similar audio quality and file conversion.
So, is there a specific time to use one instead of the other? Also, when and why do we need to use PCM instead of Bitstream?
A major drawback is that PCM only supports two-channel outputs with optical and coaxial. This can be quite restrictive for some users and a complete deal-breaker.
Compatibility is also a major factor you need to consider. By using PCM, the player decodes the audio files; however, it is not the smoothest transmission, especially if you have a very high-end and sophisticated home theater setup. If you are using a wireless sound system, this PCM method is not for you. PCM transmits large audio files that need a physical connection to make them work.
So if you are working with a wired system, this is a viable option. Did you know that PCM actually uses Bitstream technology as part of its main foundational structure? Far from it. But Bitstream most definitely has a few benefits and advantages over PCM. One of the major limitations of Bitstream is when you need to rely on secondary audio.
Generally speaking, you will get better audio quality when using Bitstream. Although this can be counteracted by using a top-notch receiver with powerful processing functions. The key benefit of using Bitstream is that you can take advantage of wireless connections.
This is impossible with PCM and a reason so many home theater builders choose Bitstream. The main thing we have come to realize when discussing the Bitstream or PCM is that they are both viable methods for converting audio files. And they are both viable options for your surround sound system. PCM is more compatible with the majority of media players, while Bitstream can generate better sound quality with the right conditions.
Is there much difference between the two? Nah, not really. You should let the build of your current home theater system dictate the route you decide to take. Until next time, happy listening.

This allows 65, different audio information to be represented.
In the DVD-Audio standard, the resolution is 24 bit. This allows LPCM can be stored in different quantization or resolutions 16 bit, 20 bit or 24 bit and in different sampling rates or sampling frequencies 48 kHz or 96 kHz. LPCM can transmit up to eight channels. There are several recording modes with different resolutions 8, 12, 16, 20 and 24 bit and different sampling rates 32kHz, What that actually is and which setting delivers the better sound is revealed here.
If PCM is selected, the PS4 takes over the audio decoding of the sound material and passes it to the AV receiver, which usually outputs it to the speakers unchanged with the specified number of channels. So if the PCM signal is stereo, the only stereo will be output. If the signal is a 5. If the PS4 is set to bitstream — regardless of the audio technology, for example, DTS or Dolby Digital — the PS4 passes the unprocessed signal to the AV receiver, which then takes over the audio decoding.
Provided it also supports the sound codec set on the PS4. PCM is therefore merely a specification that controls which device is used for decoding.
The choice depends on the quality of the individual devices — in this case on whether AV receivers or PS4s are better at decoding. In general, however, the AV receiver is usually the better choice.
After all, it is designed for such cases. I am Bob. I work as an audio engineer and audio technician. I work in mastering and arranging bridges in existing songs and the arrangement and orchestration of the chorus. In Planet HiFi I test gear for a couple of days and write a review.

The Bitstream Option. Setting the Secondary Audio. The problem with bitstream starts when the program relies on secondary audio settings. 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.
Aside from the output, both configurations work well with most DVD and Blu-ray players with no noticeable difference. You can even find a lot of players today that will allow you to switch between PCM and bitstream connection seamlessly. Finally, both PCM and bitstream need to convert audio files to analog before your speakers can produce the output that you need. 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. On the other hand, bitstream works with coded audio files, but it can support more frequencies, allowing you to produce hi-res audio.
The process may differ, but the result will still be the same. Compatibility with devices and other connection options also differ for both configurations. PCM works well with almost every device, whereas bitstream may only work for devices that support hi-res surround sound format.
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? One of the reasons is because PCM can only transmit a two-channel signal over a coaxial or digital optical connection. This type of PCM file has a variety of digital audio applications. While PCM is a digital interpretation of analog signals, you can listen to the audio data by using the signal in its digital form. To do that, you will need to send the signal to your home theater through a digital coaxial, digital optical or HDMI connection.
For the home theater system to allow you to enjoy the audio, the receiver converts the signal back in analog form. For this reason, the digital audio data has to be converted before sending it to the speakers and amplifier. That will allow you to transfer the re-created analog signal to a stereo receiver or a home theater system through a standard analog audio cable.
This type connection is available in most CD players, though some of them can also transfer digital signals through HDMI connection. This digital information series is suitable for networking, PC, and audio applications. In audio application, bitstream converts audio data into digital information bits and transfers it to a receiver. These audio signals are usually available in various surround sound formats. The receiver detects the encoded surround sound formats and proceeds to decode the information according to the instructions embedded in the bitstream signal.
It further adds additional post-processing and converts the signal in analog form. That allows the system to amplify the sound and send it to the speakers for you to hear it. A bitstream process starts with the sound mixer and content creator.
