Software release to enhance APX audio analysers

A free upgrade for APX users, the software offers a host of enhancements, including a multitone analyser that returns 19 key audio measurements in less than two seconds.

The upcoming release of APX500 v2.7 means production line managers no longer have to choose between high speed or high quality when specifying their audio test equipment, according to Audio Precision.

Consistent results will be able to be achieved with a minimum number of test stations, ensuring lower defect rates at a lower cost per unit.

The APX multitone analyser returns the following results in graphic or tabular data form: level, TD+N (total harmonic distortion and intermodulation distortion plus noise), level, noise density spectrum, gain, TD+N spectrum, noise RMS level, relative level, crosstalk, signal-to-noise ratio, deviation, crosstalk at tone, DC level, phase, total RMS level, frequency shift, phase at tone, RMS level at tone, FFT spectrum, TD+N ratio and maximum level at tone.

Speeds of 1.2s are attainable using the APX API (application programming interface), the typical implementation on an automated production line.

When the APX graphic UI is controlling the APX, speeds are closer to 2.5s for 19 results.

The APX v2.7 software powers all APX analysers, including the APX515 production test audio analyser, the APX525 high-performance audio analyser and the APX585 multichannel audio analyser.
