New version which may be used with a much larger range of sound cards. 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. General Information LAUD is a very comprehensive audio equipment and loudspeaker measurement system for developers of loudspeakers and audio electronics, and for production qualiy control. LAUD is a no-nonsense engineering system. Yet with all this capability, LAUD is still one of the least expensive full-featured systems obtainable.
