If you don’t know what DTS is please read on, otherwise you can skip straight to the tutorial.
CD’s play music in stereo, which means that there are two audio channels on the disc, left and right.

5.1 systems, use 6 speakers, 3 at the front, (Left, Centre and Right). 2 at the back (Back left and Back right) and the Frequency Effects channel (or LFE for short).

There are three methods to utilize all speakers, they are:

* Dolby Digital
* DTS Digital Surround (DTS stands for Digital Theatre System and this is the method in this tutorial)
* Sony Dynamic Digital Sound (SDDS)


The main use for DTS is to create the feel that the audio of the music or movie you are watching comes from all around you, if you watch a movie and there’s a cop car chase, you may hear sirens from the left of your living room moving over to the right whilst the rest of the movie plays from the front speakers, it’s designed to put you in the picture.

Some artists, (Jean Michael-Jarre and Kraftwork to name a couple) use 5.1 systems to enhance their music and it sounds great.

A DTS Upmix cannot replace the real thing but it’s a decent approximation. A DTS Upmix, is a way of ‘faking it’ – since the original music you’ll be working from comes from a CD which is in stereo so you need to alter the track and ensure the correct alteration is sent to the correct speaker. This normally is to create ambiance at the back, bass from the LFE and main vocals from the centre.

One final note on DVD systems, some offer you option to play your CD’s on all the speakers anyway so you may think what’s the point? – If a DVD player does this as an option, what you are getting is the left and right, played normally through all the speakers. A DTS upmix is intended to give you the original stereo from the front left and right speakers, then utilize the rest of the speakers for what they were intednded for, i.e. special effects – and this brings the experience to life.

I encourage you try this, once you know how to, it’s actually quite easy and please feel free to ask questions or if you get stuck with something, post here and I’ll do my best to offer help.

To create, you will need:

* 60 minutes (for a newbie) 30 minutes each time there after
* 4 Gig Free Space (approx)
* Freerip (www.freerip.com)
* Goldwave (www.goldwave.com)
* Surcode DTS Encoder (www.Minnetonkaaudio.com )
* CD Burning software capable of burning a cue sheet (Nero does it)



To test, you will need:

* 1 Blank CD
* A 5.1 Speaker system (normally, your 5.1 DVD player but some computers do it)


Notes:

A) Source Data: Always use an original CD when ripping music, MP3’s, even lossless encoding will not convey the appropriate data that is required for DTS up mixing. When ripping your data, rip to PCM WAV.

B) Wav File Format: When saving the files detailed in this tutorial, you must ALWAYS save them as: Type: "Wave" and set the file attributes to "16 bit, mono, signed"

C) Maxing Volume: (Steps, 8, 9, 17 & 18) – I suggest in this tutorial to increase the volume of your rear speakers to 300% - you may change this depending on your personal preference and room set up, (a smaller room requires less, a larger room requires more, tweaking this option to perfection will come with a few attempts.


Special Effects: As you explore Goldwave, you will find other effects that you can play around with, what is mentioned in this tutorial are how to get the Oops channels (Steps 7 and 15). The Oops channel is intended to create background "ambience" however after exploring you may wish to create funky effects in place of ambience. Remember, that whatever effect you create you should be aware that the volume should not drown out the volume from the front left, right and centre speakers.



01. Rip your CD to WAV (one complete wav file) and name it Master. Be sure to create a cue sheet ( your software should be able to do this) otherwise you won’t be able to burn it to disc effectively.

02. Open master.wav in Goldwave;

03. Click "Edit", "Channel" "Left"

04. Click "File", "Save Selection As..." and name the file "left_front". (Remember Note B)

05. On the Goldwave toolbar, click "Edit", "Channel"; "Right".

06. "File", "Save Selection As..." and name the file "right_front". (Remember Note B)

07. "Effects" and then "Invert";

08. Click the maximise button (wait for the scan to finish)

09. Change the maximum volume to 300% (Either use the slider or enter 9.6 dB) (Remember Note C)

10. Click on "Edit", "Channel" and "Both".

11. "File", "Save Selection As..." and name the file "right_Surr". (Remember Note B)

12. "File" and "Close"

13. Open the original master

14. "Edit", "Channel"; "Left".

15. "Effects" and then "Invert";

16. Click the maximise button (wait for the scan to finish)

17. Change the maximum volume to 300% (Either use the slider or enter 9.6 dB) (Remember Note C)

18. Click on "Edit", "Channel" and "Both". Click "File", "Save Selection As..." and name the file "left_Surr". (Remember Note B)

19. "File" and "Close"

20. Open the original master.

21. Click "Low/Highpass" button (on the top toolbar)

22. In the Filter options, click the Dynamic radio button and choose "Lowpass" filtering

23. Change the initial Hz to 80 (2000) and the final Hz to 120 (22050) Change the "Steepness" to level 5, click OK

24. Click "File", "Save Selection As..." and name the file "SubBass LFE". (Remember Note B)

25. "File" and "Close" on the Goldwave toolbar;

26. Open the original master

27. Click the “Maximise" button (wait for the scan to complete)

28. Adjust the slider to 0.5 and then click "OK";

29. Click the "Parametric EQ" button

30. Choose the Treble Boost from the "Presets" option and click ok

31. Click "File", "Save Selection As..." and name the file "centre".(Remember Note B)



Hard Part Over,

You now have 7 wav files, the original master, and 6 for the DTS Upmix, if you’re short on space and/or finished with your master, delete it.

Open Surcode DTS Encoder

32. Choose the save destination for your DTS Upmix

33. Change the sample rate to match your Wav File (Try 44.1)

34. Click the icons on the software and select the appropriate wav file

35. Click encode

Easy Part Over

If you are happy you’ve done all this right, you can delete everything except the new file you’ve just created with Surcode DTS Encoder and the cue sheet you created right at the beginning.

Burning Process

36. Ensure the cue sheet and the new DTS Wave File are in the same folder

37. Open the cue sheet with notepad and ensure the file name of the wav is the same as what the cue sheet says and add the word “WAVE” after it. (i.e. your cue sheet probably reads: “FILE "master.wav"” make sure your DTS Wav file is called Master.wav or change your cue sheet to read “FILE “example.wav” WAVE”

38. Save the cue sheet

39. Use your burning software to burn the cue sheet to disc, then whack it in your 5.1 system.

Originally posted by drewhiggins:In DVD Decrypter you can rip the 5.1 stream as an AC3 file then convert to a WAV file for DVDs, but then I think that might be lossy.

Try this, but only for an audio CD - could a WAV file be done in the same way?

9:52 PT: Hello from Cupertino! This is Macworld Editorial Director Jason Snell, reporting to you from the small theater on the main Apple campus on Infinite Loop. Members of the media, analysts, and Apple employees are filing in to this theater, which has been the location of numerous Apple product launches, including the original iPod launch. I’ll be providing your live update today, so I’m warming up my typing fingers right now.

9:54 PT: How you know it’s not an Apple music event: The music playing is classical. Classical is not my specialty, but it was a solo violin. Now some more... chamber music? “Now I feel like I’m at a wedding,” says an Apple employee behind me. Are you ready to rock? I hope not! Are you ready to classical?

9:59 PT: Lights are dimming. We’re about to get started

9:59 PT: Steve Jobs on stage. “Good morning!” Black mock turtleneck, blue jeans -- standard attire. “Everybody knows, today’s about notebooks, and we’ve got some exciting new notebooks and we want to tell you the story about how we created these things.” But first, “we want to cover the state of the Mac.” So Steve introduces chief operating officer Tim Cook to take us through the “state of the Mac.”

10:00 PT: Slide of current Mac line. Cook: Last reported quarter, 2.5 million Macs, new company record. “This didn’t just start in the last quarter. Several quarters in a row, we’ve been growing 2-3 times the market growth. Here’s why we think this is the case.” First, “better computers, far superior” to what’s out there. He cites the iMac and the MacBook air.

10:01 PT: Next: Better Software. “Software like Leopard. Virtually everyone agrees that Leopard is far ahead of Vista. And software like iLife, the best digital lifestyle suite on the market, that lets you enjoy photos, and make movies, and make music, all in an integrated package.

10:02 PT: Number 3, compatibility. He cites Boot Camp on every Mac. Shows Windows XP running on iMac. “When I look at this, it sends shivers up my sign. But it works as an insurance policy, whether you use it or not.”

10:03 PT: Next up, “something we didn’t do -- Vista.” Laughter in the audience. “I think it’s fair to say that Vista hasn’t lived up to everything that Microsoft hoped it would. And consequently, it’s opened doors for a lot of people to consider switching to the Mac. And this has given us an opportunity and Apple has been the beneficiary of this.”

10:04 PT: Great marketing. “The Mac-PC ad has struck a chord with so many switchers. They tell a story, and people listen.” And he plays one of the ads - it’s the “you’re banished” ad with John Hodgman on a throne.

10:05 PT: “Number six, retail stores. We began our journey in the retail stores just about seven years ago. And today we have 247 stores in 8 countries, and they greet 400,000 visitors each day. And most importantly, still 50 percent of the Macintoshes they sell are to people that are new to the Mac, making the people underneath the Macintosh tent larger and larger.” Shows photos of the new Sydney store and the new Beijing store.

10:06 PT: “And these are the six reasons we’d attribute to the Mac’s momentum. But this just didn’t begin. If you look at the history, what you would see that the Mac has outgrown the market for 14 of the last 15 quarters. That’s almost four years. That’s phenomenal.”

10:07 PT: “Obviously the unit share is growing. In U.S. retail, we’ve gone from a single-digit number to now, the Macintosh represents 17.6 percent of unit sales in U.S. retail. And if you look at revenue share, because we focus on fully-featured systems and we don’t compromise on quality, our revenue share is 31.3 percent. That means one out of every three dollars spent on computers in U.S. retail is spent on the Macintosh. What a difference a few years makes.”

10:08 PT: “In education, we’ve surpassed Dell to become the top-selling provider of notebooks, 39 percent. And at a major university, here’s what’s happened.” Shows a slide, starts at 2002 at 15 percent, up to 47 percent in 2008.

10:09 PT: Tim puts up a photo of a lecture hall at a college, and it’s almost entirely Mac laptops. “I challenge you to find a PC,” he says. The point is, college kids have a choice of laptops and they’re choosing Macs.

10:09 PT: New slide: total Mac units sold. Pointing out that in the first three quarters, Apple has already sold as many Macs as they did all last year. “And that’s the state of the Mac,” Cook says.

10:10 PT: Jobs is back! “With that done, let’s talk about notebooks. But before we get started, we want to talk about some technologies and discoveries we’ve made that help us build notebooks.”

10:11 PT: Jonathan Ive on stage. “I’d like to take a few moments to tell you about a real breakthrough we’ve had in how to design our notebooks. To show you the issues that preoccupy us when we’re designing these products.” First, he’s going to show how they build the current MacBook Pro. “When you’re designing a product as thin and light as the MacBook Pro, is making it strong, robust, tortionally rigid. I think you’d be surprised to know that the aluminium enclosure you see makes a small contribution to the structure. The structure is primarily derived from the internal frame. It’s made of multiple parts that are then assembled into the bottom case, which is a very thin Aluminium pressing. It’s this composite that starts to create a strong system.”

10:13 PT: Showing a series of plates on the current model that are welded together to provide more support. And finally, they add a plastic gasket. “That allows us to control the reveal of the junction between the palm rest and the bottom case. We have been looking at a new way of solving these problems, and we’ve been looking for a better way to build a notebook, and we think we’ve found it. We had a significant breakthrough that culminated in the design of the MacBook air. There is no way that you could build a product that is as thin, light, and importantly as strong and robust as the MacBook air given the architecture that I just described.

10:14 PT: “We discovered that if we started with a thick piece of aluminium and removed material to make physical features in the structure, we could make a much lighter but much stronger part. So that’s how we make the palm rest of the MacBook air.” He shows an image of an aluminum extrusion to show how the put it together. They create the “locating features,” holes in the metal. Then rough cutting, a “noisy stage” where they remove large amounts of material quickly. Remove holes for key caps, and the trackpad. Then they blast it and anodize it.

10:16 PT: “At each of these distinct stages, we’re continually collecting the material, and cleaning it, and recycling it. So we started with a solid slab of aluminium that weighed over 2.5 pounds, and we end with this remarkably precise part that ways less than a quarter of a pound. It’s also very strong. That one part forms the structure for the MacBook air. It’s the highly precise enclosure that makes the product possible. So this new way of building a notebook that we pioneered here obviously has relevance beyond the MacBook air. And we’ve been working hard to build new unibody enclosures for new notebooks.”

10:17 PT: Jobs is back. “We also have some new graphics for notebooks. Nvidia came to us many months ago and talked to us about an amazing graphics part they wanted to build, that would combine the chipset and an extremely powerful embedded graphics processor, all in one part, for a desktop computer. And we said, ‘This is fantastic, but we’d like to use it in a notebook. Can we work together on this?’ And we’ve worked with them and... it’s really great. It’s the Nvidia GeForce 9400M. It’s an amazing chip. It combines the Chipset and GPU on one die. 70 percent of the die area is the GPU. There are 16 parallel graphics cores on it, and they deliver 54 gigaflops of graphics performance. So this thing’s a stunner in performance. And in our tests we’ve found it’s up to five times faster than integrated graphics.” Slide showing performance: 2.8x in World of Warcraft, up to 6.2X for Call of Duty.

10:19 PT: Showing 55 percent performance versus the 8600M GT in the current MacBook Pro, and for general performance it’s up at 86 percent.

10:20 PT: “We’ve got a new trackpad for notebooks. It’s a gorgeous, large, multitouch glass trackpad for notebooks. It’s 39 percent larger tracking area than before, it’s multi-touch for gestures, it’s glass for silky-smooth travel. And we’ve optimized the coefficient of friction on the glass, so it’s really beautiful. And the entire trackpad is the button. It gives you more area on the trackpad and keeps you from hunting for that button. You can get multi-button support from software. And we’ve added some new four-finger gestures that are really nice.”

10:21 PT: Steve is recapping the gestures from the prior models, one-fingure ones, two-finger spreads and pinches and rotations, and three-finger slides forward and back. And now the new four-finger gesture, sliding four fingers up for Exposé activation, and sliding to the side to bring up the app switcher, then one finger to move between the apps in the app switcher.

10:22 PT: “Today we’re introducing our new MacBook Pro. Our current MacBook Pro is the best in class in the industry, and today we’re going to replace it with this. And it’s gorgeous. Full glass, instant on LED displays, you can see how thin the display is. All the connectors on [the left] side.” Black front like an iMac. “Precision aluminum unibody enclosure, LED display, next generation graphics, a multi-touch glass trackpad, a mini displauy port connector -- we’re putting that on all our systems -- and environmentally responsible.” Also the usual stuff, like backlit keyboards, magnetic latch, motion sensor, speakers, iSight and microphone.

10:24 PT: “The unibody saves us half the parts from the old model. So we’re really happy about this, and I’d like you to see it.” He’s going to pass around the unibody part.

10:27 PT: Lights are back down now. We’ve seen it and touched it. Very light, very finely detailed part, all in one piece.

10:27 PT: GeForce 9400M built into the MacBook Pro. “But even that wasn’t the best we could do. We’ve added the GeForce 9600M GT. State of the art for mobile graphics. 32 parallel graphics cores, 125 gigaflops. And we’ve included both of them in the new MacBook pro.” Graphic showing the both connected. “With the 9400M, you get 5 hours of battery life, with the 9600M GT you get four hours of battery life. You choose.”

10:29 PT: Slot-load superdrive on right side. Left side, MagSafe, Gigabit Ethernet, FireWire 800, dual USB 2 connectors, Mini Display Port. “This is what we’re going to for all video out for all of our products.” Audio in and out, both analog and optical digital, an ExpressCard 34 slot, and the battery indicator is on the side “so you don’t have to turn your product upside-down.”

10:30 PT: “We can do everything [the DVI port] can do, and at a fraction of its size. We’re building it to everything we make. It’s going to be the first MacBook Pro with a Solid-State Drive option. And you can acess the drive and the battery from a door on the bottom.” Full accessibility to the battery and drive from that lower bay!

10:31 PT: .95 inches - “This is our thinnest MacBook Pro ever. And it’s going to come in two models.” First one: $1999, 15.4-inch LED-backlit display. 2.4GHz Intel Core 2 Duo / 3MB L2. 2GB 1066 MGhz DDR 3 memory. Both Nvidia cards. 250GB hard drive. Slot-loading SuperDrive. $1999.

10:32 PT: $2499 config: 2.53GHz processor, 6MB L2, 4GB of memory, 512MB on the 9600M Gt, 320GB hard drive. Upgrades: 2.8GHz, 4GB mem, SSD, and more. “Shipping today. They should hit stores starting tomorrow.”

10:32 PT: “As you know, we have a major push here to make our products more environmentally friendly, and that involves leaving out toxic chemicals. Here’s our environmental checklist.” Arsenic-free glass, BFR free, Mercury-free, PVC-free, highly recyclable, and 37 percent smaller packaging.

10:33 PT: And for the first time for the MacBook Pro, we’ve wone an EPEAT Gold rating from the EPA.

10:34 PT: Now, “we’d like to update the MacBook Air.” So first up, graphics. Putting the GeForce 9400M inside the MacBook air. 4x faster graphics. New Air: 120GB hard drive in, and 128GB SSD option on the Air as well. “In addition to that, we’re putting in a mini display port, so you can drive all our new displays.” $1799, GeForce 9400M, 1.6GHz processor, 2GB of 1066MHz RAM, 120GB drive. Second model, $2499, 1.86GHz, 128GB SSD. Available early November.

10:35 PT: New 24-inch LED Cinema Display. “It’s gorgeous. Really, really nice. Thin.” Looks like an iMac. One cable for AC, other cable has MacSafe - power your notebook! - USB, and Mini Display Port. “Just plug this into your MacBook Pro and you’re all set. No extra cables, power supplies, nothing.” 24-inch LED-backlit display, 19200x1200 pixel resolution, built-in iSight camera * mic, built-in stereo speakers, plus the connectors, and a three-port USB 2.0 hub. Available in November.

10:37 PT: “But there is one more thing. And of course, it’s the MacBook. The MacBook is an amazing product. It’s the best-selling Mac ever. We sell a ton of these MacBooks, and people love them. They are one of the best products in the industry. We’re going to reduce the entry price today from $1099 to $999, make ‘em a little more affordable. And I think we’re going to sell them for a long time. But we’ve heard from a lot of MacBook customers, and the top three things they’d like are: a metal enclosure. They lust after the MacBook Pro’s metal enclosure. Faster graphics -- they want to play games, they’re doing a lot of intense graphics applications. And a lot want LED backlit displays, for instant-on. And we figured out a way to bring these to the MacBook line. And so we are introducing a new generation of MacBook, on top of our white plastic MacBook, and here it is. It’s an all new MacBook.”

10:39 PT: Corner-to-corner glass (black background like the iMac). Precision aluminum unibody enclosure, LED display, next-gen graphics, multi-touch glass trackpad, Mini Display Port connector, and environmentally responsible.

10:40 PT: “Eliminates more than 60 percent of the parts, and it’s much stronger.” Claims 5x graphics performance over previous MacBooks. 5 hours of battery life. Environmental checklist slide comes out again. Arsenic free, BFR free, mercury free, highly recyclable, and packaging is 42 percent smaller, and EPEAT Gold certification.

10:41 PT: Yesterday these features cost $1999 for a MacBook Pro. Starting today, you can get them for just $1299. Two models: $1299: 13.3” display, 2GHz Core 2 Duo / 3MB L2 cache, 2GB 1066MHz DDR 3 memory, GeForce 9400M, 160GB hard drive, slot-loading SuperDrive. “This is a beautiful machine.” Second model, $1599. 2.4GHz processor, 250GB hard drive, and a backlit keyboard - first for the MacBook! Upgrades: more memory, 320GB drive, 128GB SSD, and video adapters, including dual DVI.

10:43 PT: Summing up now. “We’re building both in a whole new way. From a slab of aluminum to a notebook. New graphics. New trackpad, the best we’ve ever built. And LED-backlit displays that are far brighter, instant on, far more environmentally responsible.” And once again he points out the MacBook now has MacBook Pro features but costs $700 less.

10:44 PT: Roll the video! Jon Ive talking about the design. Coldplay playing in the background -- there we go, now we’re ready to rock.

10:46 PT: Dan Riccio, VP of Product Design, now in the video. Showing the factory. It’s not every day that Apple details parts of their actual product-building process. They are obviously proud of this system and also see how it’s a good way to explain why these new models are different. Pretty clever, and good marketing, but it’s also cool to see Apple lift the veil and actually talk about what they’re building in their factories, how, and why.

10:47 PT: Bob Mansfield, Senior Vice President, Mac Hardware, is now on the video, talking about the hardware design and the story about all the parts.


10:49 PT: A little more detail on the trackpad from the video - it’s a physical press, not like the current models, where you lift up and tap. You can press while your finger is down, because it actually presses down when you push.

10:51 PT: The MacBook doesn’t seem to have a FireWire port. I don’t think they mentioned it, but I didn’t see it in the video. I wish I could TiVo it back and pause it, but Steve’s got the remote.

10:52 PT: It’s Q&A with Steve Jobs, Phil Schiller, and Tim Cook! But first, “we can’t answer any questions about the current quarter,” because the earnings report is October 21. (Tune in to Macworld for coverage of that.) Jobs: “Second, 110/70, this is my blood pressure. This is all we’re going to talk about Steve’s health today. If you want to see it go higher, ask him more questions about it.” Lights are up and let the questions about Intel stickers begin!

10:53 PT: Question about the Nvidia chip. Jobs: “We helped them, and we’re first to take it to market, and maybe the only, but that’s up to them.”

10:54 PT: Jobs talking about that DisplayPort is better for the computer industry rather than HDMI, which is for more entertainment uses. BluRay? “BluRay is a bag of hurt,” Jobs says. “The licensing of the technology is so complex that we’re just waiting until things settle down and waiting until BluRay really takes off in the marketplace before we burden our customers with the cost of the licensing and the drives.”

10:57 PT: 17” MBP is still available, being refreshed today, but won’t get the new features yet apparently. (That was my question. Thank you, thank you very much.)

10:57 PT: Jobs says he thinks “a refresh cycle” will happen with both the Pro and MacBook models. That’s code. Let me decode it for you: Jobs thinks they’re gonna sell a lot of these laptops.

10:59 PT: Tim Cook on the new production process. “We put a lot of energy to lower the price by $700 and put the features in that people have been asking for.” Jobs points out that as you learn and grow, prices drop over time. Cook points out that MacBook volumes will help drive down the production price.

11:00 PT: Touchscreens on Macs? Jobs: “We’ve certainly experimented with it, as you might imagine, and it currently doesn’t make a lot of sense to us.”

11:02 PT: And that’s it! We’ve been excused and are going next door to view the new systems up close and personal. Stay tuned for much more today and in the weeks to come at Macworld.com.
