Don’t feel like shelling out for a Sound Pressure Level meter for your home theater surround-sound speaker setup?

Apparently Matt Woodward of Deep Focus Technologies passed on buying one, and instead decided to develop an iPhone app for calibrating his speaker system—you can find the Washington-based software and tech consulting service’s Theater Tool app for $1.99 at the iTunes store.

Seems simple enough—according to the website, the application employs a distance/delay calculator so you can set the appropriate delay time between your front and rear speakers so they’re not out of sync.

Not sure if the tool goes through pink noise testing via your iPhone’s speaker, but it’s gotta come up with the measurements somehow.

An SPL meter will capture area noise and you can take the measurements to fine tune your acoustics on your theater system’s receiver. With the Theater Tool it looks like you’ll just point and click with your iPhone to get the readings, and fine tune accordingly.

The app’s only been around for a month or so—anyone try it out yet and can comment on it? Let us know below.

I have been looking for an app to do just this.

Be nice if it listened to all channels on the noise cycle generated from the receiver and had a level for each channel displayed simultaneously. Then just a case of adjusting the receiver until all the levels are the same.
