Analysis of Multimedia Audio Systems with Nonlinearities
Original language description
For measurement and analysis of multi-channel electro-acoustical systems we used logarithmically swept signals. This method uses driving the system under test by a test signal, recording of its response to the test signal, and digital analysis of obtained results. A so called "inversion filter" is derived from the driving signal. By convolution of the system's response with this inversion filter we can obtain an impulse response of the system under test. This method enables analysis of tested systems with nonlinear distortion. When analyzing multimedia audio systems it is possible to analyze channels individually or their mutual influencing. In this project we dealt with the analysis of individual components of the electro-acoustical chain and monitoring of their performance, including compression sound systems.
