Peter Mapp holds his Apple iPad running the SPL Dashboard app by Studio Six Digital, a series of four sound level (SPL) measurement displays. This is a suite of audio and acoustical test and measurement app modules for the Apple iPhone, iPad, and iPod touch. One of the more popular apps, based on an unscientific survey of my audio friends at the AES convention, seems to be Audio Tools from Studio Six Digital LLC. But if understood, these tools are great for many of the field measurements we need to make for quick checks and to determine whether other test gear needs to be brought in for a job. It's truly amazing the extent of available measurement tools that literally fit in the palm of a hand. One of these friends, Peter Mapp, principal of Peter Mapp + Associates, a specialist acoustic consultancy in Colchester, Essex, U.K., delivered one of the AES "Hot Lunch" presentations, a 45-minute talk on this very topic. So, at the 131st AES Convention recently held in New York, it was fun hanging out with some of my audio friends and colleagues and finding out not only what projects they were working on, but what test and measurement apps were on their mobile devices. I enjoy audio and acoustical tests and measurements.
