Test equipment manufacturer Audio Precision has announced the availability of Version 6 of software for the APx500 audio analyzers.
The new version increases simultaneous input types, enabling the concurrent measurement of up to 16 channels of digital and eight channels of analog audio data. The company says that the “new multi-input capability, paired with the highest channel count and widest range of digital I/O available, provides APx users critical cross-domain insight and the opportunity to reduce testing time.”
It explains, “Multi-input is especially useful for devices with digital microphones — smart speakers, mobile phones, Bluetooth headsets, and other devices — as it allows for the simultaneous measurement of the device’s microphone in conjunction with an analog measurement microphone as a reference.”
For audio devices that can have both analog and digital outputs active simultaneously, the feature enables the simultaneous evaluation of those outputs, whether in a design lab or on a manufacturing line. Concurrent measurement of both signal types also has the potential to reduce test times, which is especially important in manufacturing applications, according to the company.
The multiple-input feature is available for use in both Sequence Mode and Bench Mode and supports all the essential measurements used for the analysis of microphones and microphone arrays.
