New Video! Mike Martin walks through key loudspeaker test methods, typical test setups and then demonstrates a variety of measurements.

New Video! In this session, Joe Begin provides a detailed discussion of how to use a variety of automation and production (or manufacturing) test-oriented features.

Designed to educate engineers and technicians about everything from specific audio measurement applications to getting started with APx, Audio Test Sessions with APx are more in-depth tutorials on audio test.

The Acoustic Response measurement in the APx500 software provides a solution for measuring a loudspeaker's frequency response without an anechoic chamber. 

The measurements of “The Big Six” include phase, crosstalk, and the signal-to-noise ratio. What are they and why are they important?

In audio test, there are a small number of performance benchmarks that are most important when evaluating a device-under-test (DUT). We call them “The Big Six” measurements.

In this post, we describe the relationship between the Generator Level setting and the measured level for arbitrary waveforms, as well as a procedure to help choose an appropriate Generator Level control setting.

We will be exhibiting at several tradeshows throughout the year, and our partners around the globe will be showcasing our products.

For users getting familiar with the Bluetooth Duo module, here is a step-by-step guide to configure APx500 software (Bluetooth Duo requires v4.5 software or later) and pair it with your device-under-test (DUT).

These two modes of operating the APx500 software represent not just two different approaches to how the software is used, but also two different signal processing approaches.

With the introduction of APx500 Flex, Audio Precision is making it possible to use APx500 software with a third-party audio interface.

Why are almost all audio measurements made using a sine wave as the test or stimulus signal? Why is audio test equipment uniformly focused on sine waves?

Fast Fourier Transform (FFT) analysis, which converts signals from the time domain to their frequency domain equivalent, is incredibly useful in audio test.
