| Audio systems are evolving from traditional home stereo and home theatre to portable wireless systems capable of hands-free calling, speech recognition, and internet based features like audio and video streaming, web browsing, and email. These products are expected to work flawlessly and a lot of that depends on how well the audio system is designed and tested. The audio components include loudspeakers, microphones, crossovers, amplifiers, codecs, and DSPs. |

| With the components getting smaller it is getting more difficult to only use traditional testing metrics like total harmonic distortion (THD) and frequency response. Now system level testing is required for testing audio over the whole audio path and using more psychoacoustic tools to accurately assess the sound quality of the product. |
