LAUD measures audio band frequency response, time domain responses, impedances, spectra, harmonic and intermodulation distortion, anechoic behavior, room acoustics, and a wide variety of other characteristics of loudspeakers and audio frequency electronics. At a fraction of the cost, it dramatically outperforms other computer-card based measurement systems. Frequency Response of loudspeakers and networks , including the ability to remove echoes.
Measurements can include true phase and group delay.
Responses can be edited, combined, averaged or postprocessed to show perceived coloration. Measurements can be configured as totally synchronous, allowing coherent signal averaging and measurement of distortion products even below ambient noise levels.
