Production-Line Audio Testing
When a device that reproduces sound and contains speakers, headphone drivers, or microphones, is approved for mass production, how you test the product may ultimately have the largest influence on optimum profitability.
A good audio test system will inexpensively and quickly verify that the audio features of the product perform as designed. It will also minimize production costs by ensuring that no working product is incorrectly scrapped and maximize customer satisfaction by preventing defective devices from reaching an end user.

When evaluating the performance of a purely electronic device — power amplifier, headphone amplifier, DAC, ADC, or really any device with an electrical input or output — one thing to note is that even the simplest test will yield valuable data.
In the case of speakers, microphones, earphones and balanced armature drivers, testing the device at one frequency provides minimal utility. More commonly, and more effective in determining performance, these devices are swept across a range of frequencies of interest.
The AP Difference
When it comes to fundamentals of measurement accuracy, with key metrics such as amplitude accuracy, frequency response flatness, and residual noise and distortion, AP is unchallenged. Our analyzers are, in fact, the reference for most other audio measurement systems from R&D to the production line.
