When we think of surround sound we usually think of a multi-speaker setup. However, there are software based methods of achieving a similar effect. Virtual Surround Sound is a software based method for creating the effect of directionality from audio playback.

This makes it possible to have some impressive sounds coming from devices with simple speaker setups like phones and tablets.

Android devices are no exception and some phones such as the Samsung galaxy S line even ship with a surround sound feature.

This is quite intriguing but how does it work, and how can you enable it on your Android phone?

How Virtual Surround Sound Works

In order to gain a better understanding of virtual surround sound, it's useful to look at how regular stereo sound works. Stereo sound is made up of a left and a right audio channel. Stereo sound gives some sense of directionality due to volume differences between two channels.

Imagine being at a concert and there's a guitarist on your left and the singer is on your right. Your ears will pick up on the difference in volume coming from both people. Stereo sound replicates this.

Virtual surround sound works by fooling your brain into thinking that an audio source is coming from multiple directions when it's actually only being played back through left and right audio channels.

While stereo sound uses the difference in volume based on the location of an audio source to create a sense of directionality, virtual surround sound goes a step further by introducing a delay in playback of an audio source.

Going back to the concert example, if the guitarist is closer to you, you will hear him/her with your left ear slightly before you hear the singer with your right ear.

A virtual surround setup works by introducing a delay between the left and right channels of an audio source to mimic this. Our brains can process such a delay almost instantaneously in a real world situation and this is what allows us to pinpoint the location of sounds that we hear.

By writing clever software which introduces the delay between the left and right channels, a sense of multi-directional sound can be created.

You will need to use stereo headphone or have a stereo speaker setup in order to use virtual surround sound since it relies on left/right stereo audio output.

How to Get Virtual Surround Sound on Your Android Device

If you don't have a Samsung Galaxy S device you are still in luck. Install the Noozxoide EIZO-rewire™ PRO app and you will be able to have virtual surround sound on your device.

Download Noozxoide EIZO-rewire™ PRO

When you enable the various options Noozxoide EIZO-rewire™ PRO provides, it affects the audio output system-wide. Simply install it and enable the options you want and you will hear the difference when you playback an audio source.

On opening the app you will first need to select what type of speakers you will be using. Choose Line-out for headphones, soundbars and speakers, Built-in for onboard speakers, soundbars and HDMI outputs, or Wireless for bluetooth headphones, soundbars or speakers.

After selecting the type of speaker you will be using, the option which will actually enable the virtual surround sound is called Create VSUR on practical monitor under the NOOZXOIDE LogicSurroundES subsection.

You will also be able to choose the kind of room environment you want the audio playback to emulate. There is a Focus option which is aimed for a close-range experience. There are also 2 Studio options and 2 Live options.

There are also a few other options for tweaking the audio playback under the NOOZXOIDE Balance XEQ and NOOZXOIDE Psychoacoustics II subsections.

The options under NOOZXOIDE Balance XEQ are aimed at producing a 'versatile, warm, analogye-style sound' as the app's developer puts it while those under NOOZXOIDE Psychoacoustics II makes the speaker sound deeper and more powerful.

Why You Should Give Virtual Surround Sound A Try

Virtual surround sound may not sound as great as true surround sound but this is definitely a neat trick which will enhance your listening experience while gaming and watching movies on your Android device. Since we already spend so much time with our mobile devices, it's worth a shot enhancing the audio playback so that the best experience possible can be had.

As we covered in previous articles, Color Management for Creators – Web Browser Edition, and Color Management for Creators – ICC Profiles, it is important to embed color profiles in image data to ensure that colors are displayed as the creator intended. This leads us to the next question:
What about mobile devices, such as phones and tablets? Are images displayed on these devices as the creator intended?
Many people consume images online via a smartphone or a tablet, rather than a computer. Is it possible to see images on mobile web browsers in the colors the creators intended them to be seen, like on normal web browsers? In other words, can these mobile browsers recognize ICC profiles embedded in the images, and correctly manage their colors? In this article, we will test mobile browsers to explain how they interact with ICC profiles.

Color Space on Mobile Devices

We know that ColorEdge monitors display images in high quality and with a wide color gamut. But can mobile devices do the same? The number of mobile devices capable of displaying color spaces wider than sRGB have been on the rise in recent years. Some of these mobile devices’ color spaces are even close to covering Adobe RGB and DCI-P3. Apple adopted a wide color gamut LCD panel in its iPhone 7 and later models, and Android devices running on Android 8.0 Oreo or higher (varying by model), allow users to turn on a wide color gamut mode in the settings.

Testing Colors Displayed on Mobile Web Browsers

Measuring an iPhone 7 using ColorEdge and ColorNavigator 7

We tested how images are displayed on mobile web browsers using Safari for Apple iPhone, and Chrome for Android devices.

  • We used ColorEdge’s dedicated color management software, ColorNavigator 7, to carry out device emulation, which allows us to measure the color characteristics browsers on mobile devices.
Device iPhone 7* Google Pixel 3
OS Version iOS 13.4.1 Android 9
Browser Version Safari 13.1 Chrome 83.0.4103.101
(1) Does the browser recognize embedded color profiles? Yes Yes
(2) How are images without a color profile displayed? Displays in sRGB Displays in device’s color space
(3) Does the browser recognize the device’s color profile? Yes No
(Displays in sRGB)

* Later versions of the iPhone, and iPad Pro, show similar results when using Safari.

  • Results are from EIZO’s internal testing which was carried out July 2019. Actual results may vary according to later browser updates.


iPhone / Safari

  • The color profiles embedded in the images are recognized and displayed correctly.
  • Images without an embedded color profile are displayed in the widely compatible sRGB color space.

We came to the same results when we tested Safari in macOS in chapter 1 of this series.

Android / Chrome

  • Although color profiles embedded in images are recognized, the device’s color profile is not recognized.
  • Devices are recognized as sRGB devices, regardless of the device’s actual color space. As a result, even images with an embedded sRGB profile are not displayed correctly when the device’s color mode is set to a wide color space. To display these images correctly, you need to change your mobile device’s settings. See the next section for details.
  • Images without an embedded color profile will have their color space stretched or compressed to match that of the device, resulting in an overly vivid or bland looking image.

We came to the same results when we tested Internet Explorer with Windows in chapter 1 of this series.
To summarize, we highly recommend always embedding sRGB color profile to images, whether they are intended for mobile viewing or not. Results from EIZO’s internal testing were performed on a limited range of browsers so actual colors may display differently when viewed on other browsers or applications.

Android Color Settings

You can manually set the device to display a wide color space in the settings of supported Android devices.

Device Color Mode Measurement Results
iPhone 7 Displays in wide color space
Google Pixel 3 Natural* Displays in sRGB
Adaptive* Displays in wide color space

*The color settings may be named differently depending on the device.
The color profile of the Android device is not reflected when displaying an image in the Chrome browser. Adaptive color mode stretches or compresses the color space of the image, while Natural color mode displays a color space close to sRGB. We recommend using the Natural color mode of Android devices, to display images in the chrome browser correctly.

Summary

  • Many devices are compatible with sRGB. We recommend always embedding an sRGB color profile to images before publishing them on the web.

  • Embedding the sRGB color profile will allow the images to be displayed in the colors they are meant to be seen, even on mobile web browsers.

  • Users need to manually set the color mode of their Android device to display images in the correct colors in Chrome.
