Vizio TruVolume- The Solution to Volume Problems

One common issue with TV audio is that the volume levels can vary greatly between different channels, programs, or commercials. For example, you may find yourself constantly adjusting the volume while watching TV, as the sound can be too loud during action scenes and too soft during dialogue or quieter moments. When the volume of a video or audio fluctuates, it can result in an inconsistent listening experience.

This can be especially annoying when you have to adjust the volume every now and then to compensate for the fluctuations. It can also be distracting and detract from the enjoyment of the content, as you may miss important dialogue or struggle to hear softer sounds. Fluctuating volume levels can occur due to poor audio mixing or mastering in the content itself, or due to issues with the playback device or settings.

TruVolume aims to address this problem by automatically normalizing the audio levels and providing a more consistent listening experience. Let’s explore this further!

What is TruVolume?

TruVolume is an audio processing technology designed to provide consistent and uniform audio levels while watching TV shows, movies, or other video content. TruVolume uses advanced algorithms to analyze and adjust the audio levels in real time, ensuring that the volume remains at a consistent level regardless of changes in the source material.

This technology helps to reduce sudden changes in volume and provides a more enjoyable and immersive audio experience for viewers. It is often used in soundbars, home theater systems, and other audio devices to enhance audio quality and provide a more balanced sound output. It is also used in some TVs and streaming devices as a built-in feature to improve the overall audio performance when watching any content.

Benefits of Using TruVolume

Eliminate volume fluctuations

TruVolume helps to normalize the volume levels by automatically reducing the volume during loud scenes and boosting it during quiet scenes. This can be especially useful when watching TV shows, movies, or streaming content where the volume levels vary significantly between different programs or scenes.

Watching TV shows or movies

TruVolume helps ensure that the dialogue, sound effects, and background music in TV shows and movies are balanced and consistently audible, even during scenes with varying audio levels. This can prevent sudden loudness or quietness, providing a more comfortable and enjoyable viewing experience without adjusting the volume all the time.

Multi-channel content

Some TV shows or movies may have scenes with dialogue or actions happening across multiple channels or speakers, such as surround sound setups. TruVolume can help to balance the audio levels across all channels, ensuring that the audio remains consistent and balanced, regardless of the channel or speaker configuration.

Prevent loud commercials

Many TV viewers find that commercials tend to be louder than regular programming, which can be annoying and disruptive. TruVolume can help to mitigate this issue by automatically reducing the volume of commercials to a more comfortable level, thereby preventing sudden bursts of loud noise.

Enhance nighttime viewing

When watching TV shows or movies late at night, you may want to keep the volume levels low to avoid disturbing others in your household or neighbors. TruVolume can help to maintain consistent audio levels at lower volumes, preventing sudden loudness during action scenes or quiet dialogue that can disrupt others.

Improve audio clarity

TruVolume can also help to improve audio clarity by maintaining a consistent volume level. This can be especially helpful when watching content with soft-spoken dialogue or when listening to music, as it prevents the need to adjust the volume manually.


TruVolume can be convenient for those who prefer to have a hands-off approach to audio adjustments. With TruVolume enabled, you do not need to modify the volume during different content or when switching between sources, as the feature will automatically normalize the audio levels for you.

Vizio Truvolume

Vizio TruVolume is a feature found in Vizio televisions and sound bars, designed to regulate and maintain a consistent volume level while watching TV programs. This audio technology helps to minimize fluctuations in volume levels between different TV channels, shows, or commercials.

The TruVolume first analyzes the audio content in real-time, measuring its loudness levels using specialized algorithms. These algorithms take into account the perceived loudness of audio, rather than just the absolute volume level, which is a more subjective measure.

Once the loudness of the audio content has been analyzed, TruVolume compares it to the target loudness level specified by industry standards. If the content’s loudness is below the target level, TruVolume increases the volume to bring it up to the target level. If the content’s loudness is above the target level, TruVolume reduces the volume to bring it down to the desired level.

TruVolume also incorporates adaptive processing to ensure that sudden changes in loudness, such as commercials or transitions between different content, are handled smoothly. It uses sophisticated algorithms to dynamically adjust the volume levels, avoiding abrupt changes that may be jarring to the listener.

TruVolume is also capable of processing multichannel audio, such as surround sound or immersive audio formats, to ensure that the volume levels are balanced across all channels, providing a consistent listening experience regardless of the audio format.

To summarize, TruVolume operates in real-time, continuously analyzing and adjusting the audio levels as the content is being played, ensuring that the volume levels are normalized throughout the entire playback duration.

However, like any audio processing feature, Vizio TruVolume may not be perfect for everyone or in all situations. Some users may find that it affects the natural dynamics of the audio, resulting in an artificial or compressed sound. Others may prefer to have the original audio dynamics preserved, even if it means dealing with volume fluctuations. Other potential drawbacks of Vizio TruVolume include;

Artificial sound

Vizio TruVolume uses audio processing techniques to adjust the volume levels, and some users may find that it results in an artificial or processed sound quality. The adjustments made by TruVolume may not always perfectly replicate the natural dynamics of the original audio, and some users may perceive the audio as less authentic or less enjoyable.

Loss of dynamic range

Vizio TruVolume aims to even out volume levels by reducing the difference between loud and soft sounds. This means that the dynamic range of the audio may be compressed, with loud sounds being attenuated and soft sounds being amplified. This can result in a loss of impact or immersion, especially in content where dynamic range is intentionally used for artistic or dramatic effects, such as action movies or music.

Inconsistent performance

The effectiveness of Vizio TruVolume can vary depending on the specific audio source, content, and settings. It may work well for some content but not as effective for others. For example, if the content has already been mixed with consistent volume levels, or if you are using external audio devices with their own volume control, TruVolume may not provide noticeable benefits or may even introduce unintended changes in volume.

Compatibility limitations

Vizio TruVolume is a proprietary feature of Vizio sound bars and may not be compatible with all audio sources or devices. It may not work as expected or at all with certain audio formats, devices, or content, limiting its usefulness in certain situations.

Audio artifacts

Like any audio processing feature, Vizio TruVolume may introduce audio artifacts, such as audio delays, distortions, or glitches, especially in complex audio scenes or with certain audio sources. These artifacts can negatively impact the audio quality and overall listening experience.

How to Turn Vizio Sound Bar TruVolume On or Off

As we have mentioned, Vizio TruVolume is a useful feature for creating a more enjoyable and consistent audio experience. This feature comes in handy while watching TV, particularly in environments where there may be varying audio levels, such as during late-night viewing or when watching broadcast TV channels with different audio levels.
