There was a time not long ago when a cell phone performed no function other than what its name implied; it placed phone calls.

Today, however, using a cell phone is less about the act of placing a phone call and more about using its other capabilities.

Whether you carry a Windows Mobile, RIM Blackberry, Google Android, or Palm webOS device, you’re carrying more raw functionality and processing power into the field than was once available in even the most powerful computer.

Thus, it’s not terribly surprising that software developers found the right development platform to leverage to create some amazing tools for Audio Engineers; enter the iPhone OS.

First announced by Apple, Inc. on January 7th of 2007, the mobile phone and computing industries were thrown into a tailspin from which they are only now beginning to recover.

Featuring an App Store, hardware accessories, and multiple hardware tiers, the iPhone, the iPod Touch, and the iPad have made available to the masses an amazing set of tools which are bound to make any engineers life easier.

How, you ask? From audio testing equipment to field guides, the App Store has dozens of Apps well suited for the task at hand. Whether you’re a seasoned touring engineer or a church volunteer, you’re bound to find Apps that suite your needs. For a comprehensive review of our favorites, read on!

Testing, 1, 2
Perhaps the most valuable use of iPhone OS based devices to an audio engineer is that of an audio testing platform. Though current hardware is best suited to this task given improvements in processing power, nearly all models are up to the task. There are two major players in audio testing Apps for the iPhone OS, Studio Six Digital and Faber Acoustical Services.

Studio Six Digital’s AudioTools is my preferred suite of testing Apps, which includes SPL and RTA and can be expanded via in app purchase to include FFT, ETC, and much more.  (Editors Note: For more detailed information on Studio Six Digital, check out our recent article iSolutions For Audio Professionals)

Faber Acoustical makes an equally compelling set of Apps which includes SignalScope Pro, a suite which includes tools similar to those in AudioTools. Both applications are worthy of your use, and I’d recommend carefully weighing your needs before picking one or the other.

Attitude is always pleasant to enjoy the fruits of our labours, of course. Sometimes, however, it seems that whatever we do, it's just not enough to be able to afford that new car or that foreign holiday. So, what do we usually do then? We work harder, longer; we increase the stress on our minds and bodies; we spend less time with our families and friends; we become more irascible and less likeable people.

I am trying to sort out the Gipsy Kings wireless systems. I am renting one for this tour but your article is in perfect timing. Keep up the good work.

Thanks Kyle. In the SonomaWireWorks FourTrack forum, someone posted this question:

"I have an ipod touch, one of the latest G3 ones that are called ipod touch rather then the previous touch G2.

I have the app and it worked well with the headphone microphone that came with it (it's the one with volume controls on it too).

I'm thinking about getting another mic, so record with, but I want a decent mic that isn't directional, so that I can record our band practices. Is there something that you could suggest that will record quite well, but wont clip at high volume levels? note that by high volumes, i really mean medium. we don't play that loud.

I also read in another thread that they have clipping. so could it be that regardless of what mic I get, I will still get clipping.

Surely this 4 track should be able to cope with recording in a live band situation, where sensitive mics will clip.

Any ideas before I contact itunes and ask for a refund on this application because it's impossible to use as advertised.

And here is what Sonoma replied:

"The clipping is not a defect of the software, it is a limitation of the phone. There is currently no way of setting input gain or input monitoring. We are currently developing solutions to these problems. Please check out site regularly and join our newsletter to get all the latest updates.

So, that is what I was sorta referring to. I just wasn't very clear because I couldn't remember exactly what the deal was. I bought a cable that allows me to connect an external T-Mic as well as a Preamp. But I think the battery in my Pre is dead because it did not sound good, or any different without it.

But if you are not able to control your input level inside the phone, what's to prevent your guitar signal from being too hot before it even gets to the phone? You will have to reduce the vol on the guitar to adjust it, and that will have an effect on your tone. I really want to be able to use FourTrack to do song demos, since I have my iPod on me all the time. It's fun to program drums in Beatmaker. So for now, I have to export it thru WiFi and import it into my DAW, which is fine. But it would fun to get a guitar input to work well. It may already. But I don't think having to buy a $200 interface makes any sense! It shouldn't be this hard! Thanks!

But isn't there some issue with 3Gen iPod Touches that makes it difficult to use any of these audio programs? I have one (64gig), and have yet to figure out just how to get signal into the unit. I've tried various cables, and none work all that well. It either sounds horrible, or the level is too low. And I've read that there is no way to control your input levels. The way I understand it, is that 2nd Gen iPod Touches weren't this way? but I really don't know. I just know that I have a lot of cool app's on my iPod Touch such as Beatmaker, Looptastic, Flourish, ThumbJam, Bebot, and DopplerPad, with no real way to multitrack any of it into something like FourTrack. Line6 is getting ready to release something that allows you to midi interface with the iPod/iPhone. And Alesis has a really expensive solution. Maybe I've just not yet found the right way to go about it?
