Proloquo2Go [iTunes Link] is not your usual iPhone/iPod touch app. It turns the mobile device into a full augmentative and alternative communication (AAC) device. According to the AAC Institute, an estimated 2.5 million Americans are speech disabled to the extent that they experience significant difficulty being understood by other people. Reasons vary, but are often the result of congenital illness or ALS (also known as Lou Gehrig's disease). 75% of people using AAC devices have ALS.

One alternative is learning how to use sign language, but that requires both adequate sensory motor ability of the user and a knowledge of sign language expected in the listener. It's a solution that helps some, but not all.

When signing is not available or appropriate, using an AAC device may well be. AAC devices use combinations of symbols, words, sounds and technology to allow people without functional vocal abilities to communicate. The cost of such devices range from around US$3,500 to US$8,500 for something about the size of a Speak and Spell.

In contrast, the Proloquo2Go app has a price of US$189.99. If someone is in the market for an AAC system, it is one of the biggest bargains in the entire App Store for any iPhone or iPod touch running OS 2.1 or higher.

Proloquo2Go took the uncommon route of using existing hardware to run a complex AAC system. It's nearly impossible to describe the use of the system through words, though I'll try, but I'd suggest you check out some detailed videos walking you through the process in some depth.

We wrote about Ringtonator a while back, reader Joe's GUI program that used Cleverboy's hack to make ringtones. At the time, we were looking for a program that didn't require AAC, where you could pull any mp3 out and turn it into an official ringtone on iTunes. Then 7.4.2 hit, and we had bigger problems with ringtones than just converting them from mp3.

But now, Joe's sent us his new version, called Ringtonator Studio, and he tells us that not only will it accept any Quicktime formats, but it will also let you crop your tunes, and then translate them directly into ringtones. And, he says over on his blog, it will work with iTunes 7.4.2. That's probably a YMMV thing, but if you're really frustrated that you haven't found a way to get around Apple's lockout, it's worth a try.

And no guarantee, of course, that any ringtones made won't disappear with 7.4.3. But kudos to Joe for putting this all together, and doing his part in the fight to give us control over our ringtones.

If you're stuck at work and can't get away to take a peek at the new iTunes 7.2 update, we've put together this handy gallery of screen shots showing you the new 7.2 features. In iTunes 7.2, you'll find a new link to iTunes Plus in the iTunes Quick Links. Select it and iTunes will prompt you to update preferences (whether to use iTunes plus for your albums whenever possible) and your licensing agreement--that's another agreement on top of the one you had to agree to just to install the program.

TUAW's 7.2 gallery is a work in progress. Expect updates throughout the day as the new features come on line.

Playlist Magazine has a nice little tutorial for converting audiobooks you obtain from somewhere other than Audible.com or the iTS into iTunes recognized Audiobooks. For instance if you rip an audiobook CD, or download free audiobooks from any of a number of sites, you can convert them so that they will appear as Audiobooks on your iPod and in iTunes which gives you access to bookmarking and speed controls.

Basically, it consists of joining the tracks and converting the result to a special type of AAC (.m4b), but check out the tutorial for full details.

The other day, I said that slowing down podcasts sounded like a great job for automator. TUAW reader Dave agreed, and sent us a link to his PodastConverter (jpg) Automator action. Dave takes the long way around and follows the conventional wisdom of turning the podcasts into audiobooks rather than using QuickTime to manipulate the MP3s directly. The advantage to this approach is that the 'casts will be listenable at much higher speeds. Many people claim to be able to listen to most podcasts at 2.5x or faster. That's almost twice as fast as what you can get from QuickTime, where things start to sound garbled around 1.5x in most cases. On the other hand, converting a bunch of podcasts from MP3 to AAC takes time, processor power, and storage space, so YMMV.

Dave hasn't posted the action for download, but he has posted a JPEG of the entire action, complete with detailed instructions. So in addition to being a useful little app, this is also a great introduction to Automator if you aren't already familiar.

Call Recorder from Ecamm Network is a Skype plugin that allows you to record your calls (interviews, podcasts, etc.) as two-track AAC files for that perfect 'edited for your blackmailing pleasure' effect (calls can also be converted to MP3 for the AAC-haters in the audience). A recent version update also brings the ability to save voicemails as quicktime movies.

Call Recorder is a Universal Binary and requires Mac OS X 10.3.9, as well as Skype for Mac v1.4 or higher. A demo is available, while a license costs $14.95. As of this writing, Ecamm Network is offering a sale price of $12.95.

John Gruber pointed to a post at the Ars Technica journals by Ken Fisher (their editor-in-chief) in which he reminds everyone that AAC isn't 'Apple's format'. This is in response to all the recent buzz and speculation of Sony's announcement of AAC support; it appears that many took this as some sort of a bow to Apple's dominance.

Ken was refuting this speculation because he doesn't see it as enabling Sony to get a one-up on Apple - after all, their devices still can't play DRM'ed music from the iTMS. I think he's only partially right though. To be clear: I don't think supporting AAC will help Sony to dethrone Apple's dominance in the digital music player market anytime this millenia, but it certainly could boost their sales to all sorts of individuals who who might prefer the iTunes experience, or want to own more than one device, share libraries - you get the idea.

iTunes, the iTMS and the iPod are such a huge hit because they're all incredibly well designed and so darn easy to use. Apple's controversial philosophy of controlling both the hardware and the software has hit one out of the park - and then some. However, plenty of statistics on the number of iTMS songs per iPod can be found everywhere, and the numbers aren't amazing. I've seen everything from 5 on the low end up to 25 on the high, and I'd bet that, on average, even the newest of new iPod owners easily has far more music stuffed into their iPod by day two. Granted, a lot of people are illegally downloading a lot of their music, but they're also making that music themselves by ripping CDs from their own collection and their friends'. And what format do you suppose is the default for ripping music in iTunes? Hint: it isn't MP3. Sure, AAC isn't 'Apple's format', but the company sure is AAC's biggest pimp.

This is the music that Sony is going after. They're betting that by (finally) supporting MP3 and now AAC, their devices can play what is arguably *most* of the music that users have cataloged in iTunes. While I love the iTMS as much as the next customer (I've purchased over 520 songs from it), Sony simply doesn't need to care about not being able to play FairPlay tracks because, by comparison, there just aren't that many of them. Apple doesn't want to open their system to other manufacturers, and they don't have to - other manufacturers are (legally) coming to play in Apple's sandbox, which is mostly made up of music that is not from the iTMS.

With moves like this from major companies like Sony, I'm wondering how soon we can start declaring this market a win for Apple, but also a win for companies who can become big niche players. My Sony Ericsson Walkman phone, for example, can play AAC music and hold more than a 1 GB nano (yes - oddly, other Sony-related devices, like some of their phones, have supported AAC for a while now). And it can make phone calls. And take 2 megapixel pictures. Sure, its interface makes me want to cry, but that's why I mainly use its music abilities when I work out so I don't have to risk bouncing around the hard drive in my iPod like a pinball machine when I run.

Sony's support of AAC sure won't replace a lot of iPods, but it can offer many consumers a choice in devices for some of the other uses in their life.

That's what Advertising Age's sources are tell them. It seems 'Apple's current plans call for the ads to appear only in the lower-left corner of the iTunes library while users listen to podcasts from their computers rather than from portable devices'.

Hmm, what in the lower left hand corner of the iTunes library... why it is the little window that displays album art, and any graphics that might be embedded in an 'enhanced podcast.' Sounds to me like Apple is recommending podcasts use AAC's for their podcasts so they can embed graphics and links, though that wouldn't make Apple any money.

Let's hope Apple won't be turning our copies of iTunes into a billboard anytime soon.

It's that time again! We've put together our eighth podcast, and in this edition Jan Kabili, Damien Barrett and Dave Caolo bring you some of our best posts from last week, in-depth details on Apple Computer vs. Apple Corps, a couple April fools jokes, new Apple stores and some interesting iPod accessories. It's all hosted by me, David Chartier, and is available in a variety of formats and channels:

• enhanced AAC
  
• MP3
• our iTMS podcast and vidcast link
  
• our own RSS feed of podcasts

Please let us know what you think of the new format in the comments.

Enjoy!

Jon Udell would like Apple to be a little more open with the content on the iTunes Music Store, at least as far as the recently announces iTunes University goes. Jon hopes that Apple will provide the podcasts in MP3 format, so he can listen to them on non-iPod MP3 players (do such things exist?).

I agree that Apple should open up, and make copying and pasting links to the podcasts easier, but the AAC format is just plain better for podcasting than MP3's. Enhanced podcasts, with chapters and graphics, offer the user tangible benefits. The MP3 player manufacturers should adopt the superior AAC format; Apple shouldn't be forced to use an outmoded (though popular) format.
