Dolby Digital 5.1 Surround Sound Test Video [PORTABLE] Download

I compiled a collection of surround sound test files in various formats. Each file contains discrete channel output that plays through each speaker separately. If the test files contain more channels than your setup, you can use them to see if your system properly decodes and downmixes audio so that the sounds appear in their approximately correct locations.

The Dolby Atmos test files for 5.1.2, 5.1.4, 7.1.2, and 7.1.4 contain four audio tracks: TrueHD, DD+, and two Dolby Digital 5.1 (one with the sound effects and another that tells you that you've selected the wrong audio track). I believe Atmos should be encoded in the TrueHD and DD+ streams, but someone will have to confirm. The 9.1.6 test file has only a DD+ 5.1 track.

My tests are always using a test DTS 5.1 file which plays sound in each speaker one at a time when DTS 5.1 is active and working properly. I have an MKV version which is also on PLEX (which plays through a browser).

The channels in a 5.1 audio mix serve distinct purposes. The three front channels (Left, Center, and Right) provide crisp, clean dialogue and accurate placement of onscreen sounds. The twin surround channels (Left Surround and Right Surround) create the sense of being in the middle of the action.

While it begins with a ringing sound that should come from everywhere and nowhere at the same time, this sequence gets going as a test for your stereo pair. The whole scene is set to Bellbottoms by the John Spencer Blues Explosion. It's a song with serious attack and it needs to come across with - no pun intended - real drive. If you don't want to hear it again by the end of the scene, then your set-up is doing something wrong.

When the getaway begins, though, it's about how your surround speakers integrate with the fronts. The tyres should screech across the soundscape as the car slides about and it mustn't be so clumsy as to sound like the effect is simply chucked from speaker to speaker. Ideally, it moves across the space so subtly and seamlessly that you forget about your system altogether - not an easy thing to do when you're testing, we grant you.

Marvel means nothing if not great action, and the web-slinger is an awesome character to test big swushing surround effects. This mid-movie, first-time showdown between Spider-man and the Vulture is an excellent work-out for a home cinema set-up.

This scene starts tame, with a gentle cruise over the deserts of Arrakis, but it quickly devolves into a rescue mission as the Ornithopter nose dives and the protagonists rush out into the sandstorm to help the crew of a large spice harvester before a deadly worm attack - it'll make more sense when you watch it. What results is a sonic feast, as the sounds of rushing wind, creaking metal and frantic cries envelop you in surround sound. It culminates with a deep, guttural bass drop as the worm surfaces, accompanied by Hans Zimmer's masterful score, this is not a movie to be missed, especially if you have a good surround sound system.

It culminates in a standoff within a town square, as the baddies open fire on Bond's bulletproof Aston. The effect of bullets clinking against the armoured car, as the glass splinters and buckles is exhilarated, especially in surround sound as many scenes taken place within the car from the protagonists position. But this is Agent 007 we're talking about here, and he always has an escape plan, this time it so happens to involve the rattling machine guns strapped to the front of his car, a hissing smokescreen deployment and revving the DB5 up to perform some graceful donuts before making his escape - looking and sounding as good as ever 007.

As the chase reaches its climax, the Batmobile lets out one final roar as it jumps through a fiery explosion before smashing into the back of the Italian sports car. We're placed within the Maserati as it flips out of control, with the sound spinning around us in tandem, effectively carried out in surround sound.

As the party descends further into chaos chairs and bottles go flying, with the crashing and smashing sounds piercing through the bustle of the crowd and toe-tapping soundtrack, The main draw here is that we follow protagonist Manny as he weaves his way through this party in one long shot, putting us at the centre of the senseless chaos, making it an ideal scene to test drive your surround sound kit.

In short, passthrough is just an option that allows you to get surround sound for multiple source devices with fewer cables. It also means you can connect sources directly to the TV for the best video experience, while the TV passes on the audio duties to the receiver. Here are a couple of examples of home entertainment setups that take advantage of a TV's audio passthrough. You can either connect the sources directly to the TV if you have a soundbar with one HDMI input, or if you have a receiver with multiple HDMI slots, you can connect all your sources to that instead. However, this is only beneficial if none of the sources are new gaming consoles because you can't take advantage of the console's features if you connect it to a soundbar or receiver. Since ARC over HDMI sends and receives audio and video signals, you only need one wire between the receiver and TV.

Before we get into the individual tests, let's first talk about the different connections you can use for audio passthrough. There are three types of connections: Enhanced Audio Return Channel (eARC), ARC, and Digital Optical. ARC and eARC both use HDMI cables, and eARC is simply a newer version of ARC that allows you to pass lossless audio from DTS:X and Dolby Atmos signals. These are audio formats that produce a more life-like sound experience with additional height sound, making objects seem like they're moving in the room around you. As for ARC and Digital Optical, they both support Dolby Digital and DTS audio formats, and the only difference is the type of cable you're going to use. Additionally, eARC is backwards compatible with ARC, so if a TV supports eARC, we know ARC also works on it.

Dolby Atmos via Dolby TrueHD passthrough via eARC capability means a TV can accept a Dolby Atmos signal from a source device, when Dolby TrueHD is used as the carrier signal, and then pass that along to the receiver over an HDMI cable. Dolby Atmos is used with UltraHD Blu-rays, while streaming apps use a lossy version called Dolby Digital Plus, which means that the sound is more compressed and isn't as good as the lossless version. It means that the test is only valid if you're watching Blu-rays in Dolby Atmos and not streaming apps with Dolby Digital Plus.

To test for Dolby Atmos via TrueHD passthrough via eARC, we connect a PC to the TV via HDMI, and we connect a Sony STR-DH790 receiver in the ARC port. We make sure all the eARC settings are on, and we play an audio file in the Dolby Atmos format. If the receiver says 'ATMOS', it means the TV can pass Dolby Atmos signals. If it doesn't support it, that means the audio format is limited to Dolby Digital, and you won't get the same sound experience.

A 5.1 surround sound setup is a traditional speaker setup ideal for Dolby Digital and DTS formats, but newer audio formats use more speakers. Below you can see a 5.1 setup and where each of the speakers are positioned. Keep in mind that if there are setups with more speakers, the concept remains the same as 5.1, and you'll be adding more speakers to this configuration:

5.1 isn't the only available option you have for a surround sound setup. There are other formats like 5.1.2 or 5.1.4 for Dolby Atmos signals, which add height speakers to introduce sound above you, and a 7.1 setup, which adds two more surround sound speakers next to you. You need to find which one is best for your room and viewing habits because even if 7.1 seems like an improvement over 5.1, if you have a small room, the surround sound from the four side speakers will overtake dialogue from the front speakers.

There are several different kinds of audio encoding used to deliver surround sound in a video. The three most common are Bitstream formats called Dolby Digital and DTS, which are both compressed, and then PCM, which is uncompressed.

Unfortunately, this makes for a signal that is more difficult to transmit. For most TVs, sending a PCM signal to or from a TV will downgrade the signal to 2.1 for two speakers and a subwoofer, thus eliminating the extra channels necessary for surround sound.

Looks great for DVD player, but how do I get iTunes to recognize the multichannel settings? Testing speakers in the midi setup worked to get test tones out of my surround and sub but no go with iTunes.

I use the RCA connections to my Klipsch 2.1 Pro media speakers and a toslink optical connection to my 7.1 Yamaha AV receiver. I let my AV receiver handle all the decoding for surround sound. THX, DTS, Dolby Digital, Prologic, Cinema sound, 7 channel stereo, etc....They all work.

I am using a Roku Ultra with Sonos and the recent update caused my 5.1 to stop working. I found the info below in another thread. It seems the update enabled a Volume Mode setting as a default. Disabling Volume Mode settings fixed my Roku. I hope this helps you out. ============================== If you have any 'Volume mode' settings enabled, this may also be what's causing the issue. Use of Volume modes is not supported with surround audio, and will cause PCM (stereo) audio to be output from your Roku device. You'll want to make sure to disabled any Volume modes, such as 'Leveling' when trying to play surround sound audio.

During playback of content, press the * key on your remote. A sidebar panel will display on the lefthand side of the screen. Scroll down to 'Volume mode' and make sure this is set to 'Off'. Then check Settings>Audio>Audio mode and try selecting 'Auto' before playing content again. The source channel you are trying to play content from will also need to provide whichever surround sound format you are trying to play. For example, Netflix on Roku provides Dolby Digital+ audio format for Dolby surround. If you're not sure about a particular channel, feel free to contact that channel directly for more information about their provided audio formats on Roku.
