Epic Dolby Atmos Demo Features F-35 Squadron Takeoff and Flyover
The latest episode of the Surround Speaker Check app’s Spatial Lab video blog features it’s most epic Dolby Atmos demo track yet - a squadron of F-35 fighter jets taking off and flying directly overhead!
Source: Surround Speaker Check for iOS and Apple TV 4K
This episode features two separate recording sessions. The first recording takes place close to the studio here with the goal of capturing the overall sound of F-35 jets at a moderate distance. For the second session, a surround mic array was assembled in a field near the airport directly under the flight path, where my goal was to try and record the jets up close and flying overhead.
The F-35 multichannel tracks are meticulously crafted so the jet flyovers will translate accurately to just about any Dolby Atmos-enabled sound system
Distant Thunder
Although many folks who live near airports or air bases may be familiar with the sound of distant aircraft taking off or flying by, I nevertheless wanted to get a reference recording so we could directly compare the sound of the F-35s both at a distance and up close and in-your-face (or rather, over your head!). For this particular recording, I set up a small mic array on a hilltop at the edge of a golf course located approximately four miles from the airport. Being so far away the jets do look a bit small on camera, however, the distant roar of the F-35 is unmistakable and their powerful jet engines soon fill the sky with the sound of distant manmade thunder.
Recording F-35s in Atmos
For recording the jets passing by, I studied local maps and flight paths to come up with the optimal recording location. The idea was to create a truly epic Dolby Atmos demo for experiencing spatial audio content on home theater systems and playback devices, so I wanted to find a spot directly under the jets’ flight path. I lucked out and found a wide open field (freshly-hayed for my convenience) just over a mile out from the Vermont Air National Guard air base where I could set up my recording rig. Multiple microphones were methodically arranged to accurately capture the launch event of multiple jets in full surround sound audio, which would later be optimized in production for Dolby Atmos playback.
Additionally, I set up two cameras; one capturing the jets approaching my position, and a second facing away from the field to capture the jets after they flew overhead. I do this so I can add a little picture-in-picture frame on the screen to give viewers a look at what is happening in the rear speakers; a rear-view mirror for the home theater, if-you-will.
The preeminent demo for Atmos height speakers
Acknowledging the reality that actual ceiling-mounted height speakers are not always an available option for some listeners, the raw F-35 multichannel audio tracks are meticulously crafted so as the jet flyovers will translate accurately to just about any Dolby Atmos capable sound system, ranging from 7.1.4 or higher, down to 5.1 speaker systems and soundbars. However, those with actual height-enabled systems will especially appreciate the localization of multiple fighter jets flying overhead!
Although I found taking video of jets moving through the sky at 400 mph a bit of a challenge, I believe the audio recordings turned out fantastic, and accurately recreate the sounds of the jets exactly as I heard them live.

How to Test Dolby Atmos on Apple TV with Surround Speaker Check
In this article, we’ll discuss how to test Dolby Atmos on Apple TV 4K hardware using the Surround Speaker Check app for iOS and tvOS.
Recommended: Surround Speaker Check
When it comes to offering a theater-like audio experience on home theater speakers, smart TVs and sound bars, Apple TV 4K largely relies on Dolby Atmos to delivery the goods. As such, those looking to get the most enjoyment out of their movies, spatial audio music, and TV shows will want to make sure their Apple TV is connected to a Dolby Atmos-compatible speaker system or sound bar.
Surround Speaker Check can provide a quick and easy way to test Dolby Atmos on your home entertainment system.
However, with a multitude of Atmos-compatible speakers available to chose from, determining whether Dolby Atmos is actually set-up and working properly is not always as straight-forward a process as it seems. Read on to learn how the free Surround Speaker Check app can provide a quick and easy way to test Dolby Atmos on your home entertainment system.
Are you ready?
Before performing any tests, you’ll want to make sure your playback device actually supports Dolby Atmos. If you’re unsure of this, check your manual or look up the speaker model online for its audio format capabilities. You can also look to see if the Dolby Atmos logo is present on the device itself, although ultimately a manual will still be useful in case you need to enable any audio-specific features or sound processing modes. Once you are sure your device is Dolby Atmos-compatible, you can proceed to use the Surround Speaker Check app to test your audio set-up.
Note: If you have the iOS version of Surround Speaker Check, tap the AirPlay button located in the upper right-hand corner of the screen to make sure your iPhone or iPad is connected and ready to AirPlay test content to the Apple TV.
Test your surround speakers
The free “5.1 Speaker Check” test track covers the majority of speaker systems on the market today, and has long proved an invaluable tool for home theater enthusiasts. The test works by using specially-produced music tracks to isolate the front and rear speakers one-at-a-time, while on-screen 3D animation coordinates with the audio to let you know which speakers are being featured. If you don’t hear music emanating from a particular speaker (highlighted as a blue speaker on the TV screen), check with your device user manual to make sure your speakers are properly connected and set to decode Dolby Digital or Dolby Atmos audio signals. Users of smart TVs and Sonos-style sound bars should make sure their firmware is up-to-date.
“4.0 Speaker Check,” also a free track, offering a similar test using a blues-style music track mixed with the ambience of a packed music hall.
Test your height channel speakers
The latest speakers systems and sound bars allow for more accurate spatial imaging by including extra speakers beyond the standard stereo or 5.1 surround configurations, in order to address the “height” capabilities offered by Dolby Atmos. Commonly referred to as height speakers, these extra speakers are typically found as the topmost, upward-firing speakers on a sound bar, or as dedicated speakers installed directly on a ceiling. Speaker configurations with height channels included are typically labeled as 5.1.2 or 7.1.4 systems, where the third digit denotes the inclusion and number of the extra height speakers. Whether your height speakers are of the upward-firing variety or consist of dedicated ceiling speakers, Surround Speaker Check’s new “Spatial Suite” section offers comprehensive testing for systems with height channels, which can be helpful when installing, troubleshooting, or just fine-tuning your audio set-up.
Included in Surround Speaker Check’s new Spatial Test Suite is a new “Manual Speaker Check” feature. The Manual Speaker Check allows you to play a continuous audio loop on any one particular speaker of your choosing, including the height channels. There are three different loops included to help evaluate and troubleshoot speaker performance. When coupled with a decibel meter, the pink noise loop offers a convenient way for users to fine-tune their surround speakers levels. This is especially handy if your sound bar lacks any on-board calibration tools!
Experience spatial audio demos
One of the key features of Dolby Atmos is that it recreates audio sources, such as musical instruments or sound effects, as virtual “objects” and uses a coordinate-style method to accurately position audio within a space. The advantage of this object-based positioning over the traditional channel-based surround formats of the past (beyond more accurate positioning of audio thanks to the new height channels), is that immersive audio can then be recreated on just about any Dolby Atmos-compatible system without requiring users to install a specific configuration of speakers.
The F-18 Fighter Jets track makes a great spatial audio directionality test
Surround Speaker Check’s Spatial Object tracks lets you hear how accurately your system represents audio objects by using on-screen 3D imagery to depict objects and their placement in the room. The F-18 Fighter Jets track in particular makes a great spatial audio directionality test for sound bars and speakers (and even AirPods), as it features high-resolution recordings of actual F-18 fighter jets flying by at multiple speeds and altitudes.
New demos every month
Once your system is up and running, you’ll of course want to hear content demonstrating the full power of Dolby Atmos immersive audio in your own home theater. And while there are now plenty of movies, TV shows, and music tracks on Apple Music employing Dolby Atmos audio, finding those truly exciting “spatial moments” can sometimes be hard to find, or are just too few and far between. (And rightfully so, as overuse of such effects would potentially distract the audience from the storyline or music listeners from the song lyrics.)
