Audio Precision has just introduced custom reports, .wav file analysis, and Dolby TrueHD support as part of the latest software update for APx audio analysers, APx500 v2.5.

Custom report layouts allow users to place measurement results from APx into a MS Word document. Any value or graph can be placed in any order, allowing APx reports to match corporate style guidelines or be inserted into larger product reports automatically.

For example, AP already offers a set of projects that automate the Dolby and DTS compliance tests for AV receivers, HDMI decoders, and Blu-ray players. These projects now save results in a format suitable for direct submission to Dolby or DTS.

“Engineers should be spending time on audio innovation, not cutting and pasting all day,” says Daniel Knighten, Director of Products at Audio Precision. “Custom reporting is another example where APx saves time, adds value and makes life a little easier.”

With APx500 v2.5, APx users can import and analyse .wav audio files, using an acquisition saved by a contract manufacturer’s audio analyser to verify test results. File analysis is also useful for measuring the input quality of devices such as digital audio recorders, PC soundcards, and digital signal generators.

For HDMI testing, APx can now generate the lossless Dolby TrueHD file format and can capture a raw encoded bitstream for later analysis. Several distortion and regulation related features have been added for power amp testing, and the software has new features to improve workflow. One of these is allowing AP2700 or ATS files to serve as pass/fail limits.

APx500 v2.5 works with any model of APx audio analyser, and it is a free upgrade for APx users available from the company’s website.
