19 Audio Measurements in 1.2 Seconds

22 November 2010 - Audio Precision announces v.2.7 software for its APx range of audio analysers. Available as free upgrade for APx users, the new software offers a host of enhancements, including a new multitone analyser which returns 19 key audio measurements in well under two seconds.

This milestone of comprehensive audio test in less than two seconds means production line managers no longer have to choose between high speed or high quality when specifying their audio test equipment. They will be able to achieve reliable, consistent results with a minimum number of test stations, ensuring lower defect rates at a lower cost per unit.

The new APx multitone analyser returns the following results in graphic or tabular data form: Level, TD+N Level (total harmonic distortion and intermodulation distortion plus noise), 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 1.2 seconds 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 2.5 seconds for 19 results. The new APx v2.7 software powers all APx analysers, including the new APx515 production test audio analyser, the APx525 high performance audio analyser and the APx585 multichannel audio analyser.

Price and availability

APx500 v2.7 is a free update for all APx users. It will be available for download in mid-December, 2010 from http://ap.com/downloads/apx. Analyser prices start with the APx515, priced at $6200 in the US and under £4000 in the UK.
