Audio analysers check out playback-only devices

New application software enables Audio Precision audio analysers to quickly and accurately test playback-only devices.

Audio Precision, the leader in audio test and measurement, has announced the availability of the QuickTest application to enable Audio Precision audio analysers to quickly and accurately test playback-only devices.

With sales of personal audio devices forecast to double or even quadruple in the next five years, fast, accurate testing is a crucial competitive differentiator in the consumer electronics industry.

The two-fold challenge facing manufacturers is that playback-only devices lack the audio inputs that makes it easier to take proper measurements, and QA testing on the production line needs to be completed quickly without requiring training or programming to acquire data and interpret results.

In response to customer requests, Audio Precision has developed a special application for testing playback-only devices with the company's world-class audio analysers.

QuickTest is a macro that launches a simplified interface for the Audio Precision ATS-2 and 2700 Series audio analysers and automatically measures the performance of devices by playing a proprietary "multitone".

Results for DC offset, output level, distortion, frequency response, phase deviation, noise and crosstalk are displayed on screen against predefined pass/fail limits and all measurements are saved in a file for later analysis.

A single device can be tested in under 30 seconds, compared with two or more minutes with other solutions.

"Our customers have been facing this challenge of testing playback-only devices for some time", says Daniel Knighten, Head of Audio Precision Technical Support.

"With so many new models coming out so fast, they needed the accuracy of our equipment on the production line without dedicating one of their engineers to testing all day".

"QuickTest solves both problems at once".
