Abstract
A comparison of two sound extraction methods from guitar string video recordings is presented in the paper. A brief overview of highframe rate camera technology and possible applications are included. The method using the image analysis from two such cameras is presented. The cameras are placed at the angle of 90 degrees for recording the image in three planes. The results achieved with the setup proposed by ourselvesare comparedto the results of recording with a single highframe rate camera used for the Visual Microphone method developed by scientists from MIT. Spectrograms and signal spectra of recordings were compared and discussed, revealing that both methods of sound extraction from video brought the ability to reproduce sound, but with some distortions.Finally, the options for future experiments are considered.
