20: SoundMap (working from home with SoundCheck)

Cam Ruffle-Deignan walks you through a demonstration of SoundMap, SoundCheck’s Time-Frequency analysis module, showing how Short Time Fourier Transform, CSD, Wigner Ville and Wavelet analyses can be used for detailed offline analysis of devices. Time-Frequency analysis methods are useful for impulse response analysis and detection of loose particles and Rub & Buzz in loudspeakers and identification of transient effects such as drop out in digital devices including VoIP and Bluetooth headsets.
