cb taper has one on his iphone that is surprisingly accurate.
SPL by Studio Six DigitalAs a musician, you should be concerned about your exposure to high sound pressure levels; remember, time + exposure = loss, and once your hearing is gone, it's gone. Whether you're a weekend warrior, a professional touring musician, or a sound engineer in the studio or live, you owe it to yourself, and your career, to keep your ears as healthy as possible.SPL is a wonderful app that allows you to plainly see how loud you're getting on stage or in the studio. It's also one of the first SPL-metering apps to be accurate. In testing my copy, I found that it was only a few decibels off of my calibrated Smaart rig! Even so, SPL allows you to match the calibration of another device, so I know that when my iPhone is reading 100db, my Smaart rig at FOH is aso reading the same.Pro-grade features include your choice of weighting (A or C), a maximum SPL readout (resettable), as well as a reference field to capture variances in the room.SPL is an absolute steal at $5.99; compared to a handheld solution (many of which retail for $50 to much more), SPL is fully-featured without the pro-quality pricetag.
Upon reading some of the iphone SPL app reviews, it looks like the major limitation is that they cannot detect greater than 108dB SPLs, so that may limit their usefulness for the average loud rock show.
