ASC VS DTS | Let’s Differentiate Both Technologies

In the world of audio technology, when we discuss high-quality surround sound for a home theater setup, two acronyms often pop into our minds: ASC and DTS. Most people are often confused about the difference between these two technical terms.

Both ASC “Auto Sound Calibration” and DTS “Digital Theater System” are digital audio encoding and calibration technologies, each with its own unique applications and features. These surround-sound technologies make your home theater experience more immersive and enjoyable.

In this blog post, we’ll clarify the differences between ASC vs DTS, their features, strengths, and weaknesses. We’ll also provide some tips on how to set up each technology to get the best possible sound quality.

By the end of this blog post, you’ll have a clear understanding of both technologies and be able to make an informed choice based on your specific needs.

ASC vs DTS: The Quick Difference

ASC and DTS are two different surround-sound technologies. These technologies are used in a variety of devices, including TVs, soundbars, and theaters, to make your TV shows, movies, and music more enjoyable.

Both audio encoding technologies have many differences, with the primary difference being in their compression methods and use cases. ASC employs lossless compression, while DTS utilizes lossy compression. ASC retains every detail of the original audio signal, while DTS sacrifices some audio data to achieve more efficient compression and smaller file sizes.

ASC is most commonly used for professional audio production and archiving, broadcast facilities, and recording studios where audio quality is necessary. However, ASC is less common on consumer devices because of the larger files it delivers.

while DTS is ideal for consumer settings such as home theater systems, streaming platforms, and Blu-ray discs. With DTS, you can enjoy excellent audio quality with significantly fewer storage and bandwidth requirements, making it accessible and useful for everyday entertainment needs.

You should choose between ASC and DTS based on your specific audio requirements, whether you prefer maximum audio quality “ASC” or efficiency and compatibility “DTS“.

Now, let’s dive deep into each technology for a more detailed understanding.

What is ASC?

ASC stands for Auto Sound Calibration or Adaptive Sound Control. This audio encoding technology enables lossless sound encoding for professional audio production and archiving.

LG developed this proprietary technology in order to automatically optimize sound output to match the content being played on a device. To determine the appropriate sound settings, ASC considers a variety of factors, including the type of content, the volume level, and the environment.

Audio professionals often use this system for recording studios, broadcast facilities, and other professional audio applications.

How to Set Up ASC

You can set up ASC on a device by accessing its settings menu. In the settings menu, locate and enable the ASC option. To get the best results, you may also need to adjust the ASC settings. 

If you use the ASC function, the device will automatically identify the distance between speaker channels or create higher levels while moving or installing the unit, resulting in a 5.1-channel sound field that matches your environment perfectly. It is necessary to press the ASC button. Each channel’s distance and level will be displayed on the display.

  • To connect the ASC microphone, use the input jack on the ASC.
  • Your ASC microphone should be placed in the area where you wish to listen.
  • Click the ASC button to activate it.
  • If you want to create the best 5.1-channel sound field, you should select the following settings: L ➞ C ➞ R ➞ SR ➞ SL ➞ SW.
  • When you see the Remove MIC message appear in the display, unplug the ASC microphone.
  • You can remove the ASC settings by clicking the ASC button. On the screen, the message Cancel ASC appears after the test tone output ceases.
  • Press and hold the ASC button to listen within the Auto Sound Calibration option.
  • You can toggle between ASC ON and ASC OFF on the display.
  • You will hear music in the ASC model when you select “ASC ON.”.
  • You will hear the audio in the sound setup mode if you turn off ASC.

What is DTS?

The Digital Theater System (DTS) is a surround sound technology that uses digital signals to encode and decode audio. With DTS, the soundstage is wider and the sound effects are more realistic than with ASC.

Devices that support DTS are more common than those that support ASC. Movie theaters can play movies with high-quality surround sound using this technology.

How to Set Up DTS

The setup of DTS is also a simple and easy process.

  • Make sure that your Xbox is connected to a DTS:X soundbar or a multi-channel home theater system before you begin.
  • Then, download the DTS sound controller app from the Microsoft Store on your Xbox.
  • If you have DTS:X installed on your Xbox, select it as your bitstream codec in the Xbox system sound options.
  • Now you’re ready to go.

You will need to follow different steps depending on the device you are using to set up DTS. However, the general process is the same.

Some Additional Tips

You may also find these tips helpful when setting up ASC and DTS:

  • Make sure the speakers are positioned correctly. Using the instructions that come with your speakers is the best way to accomplish this.
  • Adjust the volume of each speaker. By doing this, you will be able to create a balanced soundstage.
  • Try different sound settings to find out which one suits your room best.

Important Note

Besides ASC and DTS, other surround sound technologies are also available, such as Dolby Atmos and Dolby Digital. Dolby Atmos offers the most immersive listening experience available thanks to its highly advanced surround sound technology.

It is, however, the most expensive technology. You can still enjoy good sound quality with Dolby Digital at a more affordable price. The following factors must be considered when choosing a surround sound system:

  • The type of content you’ll be listening to
  • Your room’s size
  • Your budget you’ve

These factors will help you narrow down your choices and find the best surround sound technology for your needs.
