Audio Precision updates measurement software
- Details
Multiple simultaneous input types, or multi-input, is the ability to activate a second input type on any APx modular audio analyzer, or APx515 analyzer, and make measurements simultaneously on analogue and digital signals.
With two input types enabled - for example, analogue for one or more reference microphones and PDM 16 for an array of MEMS microphones - there will be measurement results for every enabled input channel. In addition, the sensitivity or gain function of digital microphones and other converters can be directly found via a new derived result, Sensitivity, which displays the RMS Level relationship between the analog and digital inputs.
The multi-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. This includes Transfer Function, a dual-channel FFT analysis function added in the previous release of software. With multi-input and Transfer Function, the complex, magnitude and phase, relationship between multiple analog or digital microphones or other cross-domain devices can be found.
For audio devices that can have both analogue and digital outputs active simultaneously, the new multi-input 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.
“Our latest major release of APx software delivers a powerful new capability with broad application in both the design and manufacture of audio products,” stated Mike Flaherty, Audio Precision chief executive officer. “Whether providing added insight to the design engineer or accelerated test time for the manufacturing engineer, multi-input demonstrates the power and value of APx audio measurement software.”
Release 6.0 is compatible with all analysers in the APx500 Series. An APx KeyBox is required to run v6.0 on Legacy APx analyzers. APx KeyBoxes already installed on Legacy analyzers (for v4.6 and 5.0), are also compatible with v6.0 and only require an updated license file once an upgrade is purchased.
