When it comes to soundbars, one of the most important decisions to make is the type of audio format to use. Two of the most popular options are PCM (Pulse Code Modulation) and raw audio. Both have their own unique advantages and disadvantages, and understanding the differences between the two can help you make the best choice for your soundbar setup.
What is PCM Audio?
PCM audio is a digital representation of an analog audio signal. It works by taking a continuous analog signal and converting it into a digital signal by measuring the amplitude of the signal at regular intervals. This digital signal can then be transmitted, stored, or processed for playback.
One of the key advantages of PCM audio is that it is a widely-used and well-established format. It is compatible with a wide range of devices and software, and it is the standard format for most commercial CDs and digital music files.
What is Raw Audio?
Raw audio, also known as linear PCM, is a digital representation of an audio signal that has not been compressed or processed in any way. This means that the signal is a direct representation of the original sound, without any loss of quality or data.
One of the main benefits of raw audio is that it offers the highest possible audio quality. Since no data is lost during the compression or processing of the signal, the sound is as close to the original as possible.
Comparing PCM and Raw Audio
While both PCM and raw audio have their own unique advantages, there are some key differences to consider when choosing the right format for your soundbar.
Compatibility: PCM audio is the more widely-used and compatible format, making it a better choice if you want to ensure that your soundbar will work with a wide range of devices and software.
Quality: Raw audio offers the highest possible audio quality, since it is a direct representation of the original sound. This makes it the better choice if sound quality is your top priority.
File size: PCM audio is typically smaller in file size compared to raw audio, which can be beneficial if you have limited storage space.
Understanding the Benefits of PCM Audio for Soundbars
While raw audio may offer the highest possible audio quality, it is not always the best choice for a soundbar setup. PCM audio, which is a widely-used and well-established format, offers its own unique benefits that make it a great choice for soundbars.
Improved Compatibility
One of the main benefits of PCM audio is its compatibility with a wide range of devices and software. This is because it is the standard format for most commercial CDs and digital music files. This means that your soundbar will be able to play a wide variety of audio content, from commercial CDs to digital music files, without any issues.
Smaller File Size
Another advantage of PCM audio is that it is typically smaller in file size compared to raw audio. This can be beneficial if you have limited storage space, as it will allow you to store more audio content on your soundbar. Additionally, smaller file size can also help in faster loading and streaming of audio files.
Improved Sound Quality
While raw audio may offer the highest possible audio quality, PCM audio is still able to provide high-quality sound. This is because it uses a high-quality sampling rate, typically 44.1kHz or 48kHz, which ensures that the digital representation of the audio is as close to the original sound as possible. Additionally, many modern soundbars also have advanced digital signal processing capabilities that can further enhance the sound quality of PCM audio.
