Audio test breaks through the barrier

Audio Precision has broken audio production test speed records with a multitone analyzer that returns 19 key audio measurements in 1.2 seconds. This means production line managers no longer have to choose between high speed or high quality when specifying their audio test equipment.

The multitone analyser is available in the upcoming release of the company's APx500 v 2.7. It 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 1.2 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 APx v2.7 software will power all APx analysers, including the APx515 production test audio analyzer, the APx525 high performance audio analyzer and the APx585 multichannel audio analyzer.

APx500 v2.7 is a free update for all APx users. It will be available for download in mid-December, 2010 from . Analyser prices start with the APx515, priced at $6200.
