Foreword
This page gives you access to high definition audio test files, with sample rates as high as 192 kHz. Unlike our other sections, these sounds won't play online: higher sample rates are not your browser's best friends, and cannot be encoded in the mp3 format either. Instead, these high definition files will download straight to your disk as uncompressed .wav files.
The purpose of these test tones is to offer you a way to assess the quality of your digital audio interface or digital-to-analogue converters, when fed with high-definition sample rates. These rates are able to reproduce frequencies beyond the human hearing range but can generate aliasing in the audible range too.
Use the frequency sweep files to determine if what you hear strictly relates to the input file's content, or comes from deficiencies in your high-end digital audio system as well.
High Definition Frequency Sweeps
These sweeps start from 1 Hz up to the Nyquist frequency (half the sample rate) in a 30-second time span (linear time sweep), playing at -3dBFS.
The test starts by playing frequencies that are in your hearing range, and then they will steadily increase. As the sweep enters ultrasonic range, the sound will fade away. Listen carefully; the rest of the file should remain perfectly silent.
If you hear anything while the file sweeps the ultra-sonic range, either you have bat-ears, or - more likely - your digital audio system suffers from severe aliasing.

High Definition Chirp Tones
Chirp tones are similar to sine sweeps, but span the whole frequency range in a much shorter time: here 0.5 seconds. Each chirp tone plays at -3 dBFS. Use these files to measure frequency responses, or capture room reverberations through the impulse response method.

High Definition White Noise
White noise is characterized by a flat power spectral density: the signal contains equal power within a fixed bandwidth at any centre frequency. All files are 30-second long, and play at -3 dBFS.

High Definition Pink Noise
Pink noise is characterized by a power spectral density that is inversely proportional to the frequency: each octave carries an equal amount of noise power. All files are 30-second long, and play at -3 dBFS.

Penteosurround: how about 30 sec audio bites?
Sivadselim: I have dvd movies with surround sound. I was more interested in listening to a surround sound piece of music though.
Don't think that is possible, otherwise what would be the point of buying a hirez player.
Oppo is a great line, I have the 980 and love it. It has played just about everything I have thrown at it, sacd, dvda, divx etc.
Forgive me if I read that incorrectly.
Follow your bliss!
My Blu-ray Collection
My SA-CD Collection
1) No hi-rez player now, I know I can't play them, not looking to.
2) 95% sure I'm getting a Oppo primarily for SD DVD playback. Thus enabling both DVD-A and SACD playback.
3) Would like to have inexpensive means to get feet wet in hi-rez audio once/if I own player.
4) Doing my homework (trying to find sources for hi-rez audio software) ahead of time.
Thank you for your time and assistance.

Ok - Sorry for any confusion. Here's the facts:
1) No hi-rez player now, I know I can't play them, not looking to.
2) 95% sure I'm getting a Oppo primarily for SD DVD playback. Thus enabling both DVD-A and SACD playback.
3) Would like to have inexpensive means to get feet wet in hi-rez audio once/if I own player.
4) Doing my homework (trying to find sources for hi-rez audio software) ahead of time.
Thank you for your time and assistance.
If you're going to get an Oppo be advised the 980H Oppo player ignores the watermark. This means you can make back-ups of watermarked discs and they will play, most players stop playback after 15 seconds.
For all those who are DTS vs. AC-3 combatants, it would be interesting to see if you find any difference in them, since the Focused Center masters are both the same.

Why go the distance and create 5.0 and not go the extra inch and add the .1, the sub track? Why include the sub track in other channels?
There is no such thing as a 'sub track', there is a LFE (low frequency effects) track. Don't automatically equate or confuse that with something specifically for the subwoofer. Your subwoofer can play back the LFE track, but it also can ignore it. By the same token, the LFE track can be diverted to the surround speakers if you don't have a subwoofer, and have full range surrounds. It all depends on your own setup, so music doesn't necessarily use the LFE channel at all.
LFE tracks (the .1) are historically to be used exclusively in motion pictures for special low frequency effects (explosions, earthquakes) per Dolby mix guidelines. Although some music mixers do put sub bass in the LFE, it has traditionally been frowned upon to do so, since the LFE channel is ignored when downmixing. In other words, nothing that is 'necessary' can be put in the .1 channel since it's not a real channel, it's just low frequency effects that are entirely optional, and your own home system is more than capable of doing the same thing, that is, diverting sub bass from the surrounds to the sub.
Your own home system should be set to divert bass from the 5 surrounds into the sub; the music mixer can't know which speakers you own that are full range and which aren't, so they put the bass in the sides, leave the LFE channel empty, and let you decide how to manage your bass. It's not like the old stereo days when we just assumed two full-range speakers. We've spent 14 gazillion threads on this one..
In Penteo's case, DTS and DVD-A mixes get a touch of sub-bass in the LFE, since they're straight pipes. AC-3 mixes do not, since Dolby handles bass management through your own setup.
-John
yeah! go to Dolby's website and they have some demo's you can download. BUT. the file types aren't supported by the ps3. so you'll have to download a program onto your pc called 'XviD4PSP' you can import a file and play around with it depending on what file type you need it to be. I found that you'll want the video encoding to be an mpeg 4 (mp4) and the audio to type to be AC3. then once you encode it you can export it to windows media play (or whatever else will work for you) then choose to open it in a separate folder then just drag the file onto a flash drive then copy it to your ps3! the video quality isn't the most amazing but the is great! hope this helps! :)

What i would like to get my hands on is a VOB file with DD5.1 sound that tests out the audio, e.g. a voice that says 'Front Left', 'Front Right', 'Surround Left' etc with the voice coming out of the apropriate speaker.
Is there anywhere i can get one of these from the net, or would it be possible to create one?
Thanks in advance.
Steve.

- #2Your amp should have test tones for setting up a 5.1 system, granted it's not voices but it will do the job.
Putting that aside AVIA do a couple of DVD's that are designed to optimise a home cinema (audio/video) setup and the R1 5 star edition of MASH has a THX setup section on the first disk. - #3i got a dvd like you require from 'PoundZone' the other day, superb it is, and only a pound!
Dan - #4I have thrown together what you are looking for (anything beats revision - who needs a degree anyway!)

Full 5.1 test with LFE channel.
Hope that helps.

Cheers. Exactly what i needed.
Out of interest how did you make that VOB file? I ask because i once downlloaded some DD5.1 WAV files from the net but my DVD player wont play them (just get electronic noise). As my player can play DD5.1 Vob files but not 5.1 Wav files, are there tools that can convert/encode 5.1 WAV audio into a VOB file? - #6Vob is not really a file type as such, it's more a container inside which video and audio streams are multiplexed together.
The 5.1 audio(indeed any of the dolby audio systems) format is ac3 files. You can get software which would encode the wavs that you downloaded into an ac3 file. Then multiplex that .ac3 file with a video file and you have a vob (or .mpg, they are just the same thing).
The software to accomplish all of this is out there. Plenty of it is freeware and available.
Sites such as
http://www.doom9.org/index.html
http://www.dvdrhelp.com/
have plenty of info and guides on how to create ac3's and test files such as the one I made.
If you have any probs with it all then give me a shout, it has taken the best part of a year for me to get skilled with mpg/dvd methods and rules.

Out of interest, i have a few DivX files that aparently contain 5.1 sound. Would it be possible to convert this into a vob file but have the video in a VCD or SVCD format (so it can still fit onto a CD-R)? - #8If all else fails, if youve got Star Wars Episodes 1 or 2, there is a THQ testing utility in the sound menu that I use (in fact used last week).
2. Does the issue occur only with games?
Follow the below steps to check the sound settings:
1. Right click the speaker icon in the corner.
2. Select 'playback devices'
3. Select correct speakers and click on 'configure' (lower left)
4. Walk through configuration menu. Make 5.1
5. Select correct speakers and click on 'property's' (lower right).
6. Select Tab 'Enhancements'.
7. Check 'Speaker Fill'.
Hope the information helps. Please let us know if the query is unresolved, we will be happy to assist you further.
I have an ASUS MB (M5A78L-USB3) with a VIA chipset for audio, it WORKED great in Win 7. Windows 10 it tests fine, but only the front two speakers and bass work. 5.1 does not output sound from the rear jacks, i.e., rear and center TEST OK but DO NOT playback via a web browser. Pirate movie download sites. Spongebob episodes download free mp4. I have TWO computers with the exact same thing. On Win 7 I could use the VIA application, that however, will not load or install with Win 10. Any advice (other than the obvious) would be great.
I have been trying to find a WORKING 5.1 surround sound, and the ones I find all seem to end up being 2 Channel, no matter where I download them from. Can you learned chaps link me to a decent 5.1 setup AV file, that I can download and actually convert it to play on my BD and AV system.
I have been looking at these but I dont understand how to convert them so they both play and have a genuine 5.1 signal.
