Hot Lunch: Acoustic & Audio Apps
Presenter:
Peter Mapp, Peter Mapp Associates - Colchester, Essex, UK
Abstract:
The introduction of the iPhone, iPod, and iPad has led to the generation of several acoustic and audio measurement apps for these highly portable and popular devices. Applications range from simple sound level (SPL) measurement to slightly more sophisticated 1/3 octave real time analysis to advanced FFT (Fast Fourier Transform) programs with full complex transfer function computation. This latter category of app can enable high resolution frequency response and phase measurements to be made or the system impulse response to be derived—which opens up a whole further raft of acoustic measurements to be made. Other apps make making full use of the host device’s computing power enable a wide range of test signals to be generated or even highly sophisticated measures such as STI and STIPA speech intelligibility to be performed. But are these apps valid tools for the audio pro or merely gimmicks for the geeks and nerds ? Come to the hot lunch session and find out.
