Beaverton, OR - Jan 29, 2010 - Audio Precision has introduced custom reports, WAV file analysis and Dolby True HD support as part of the latest software update for APx audio analyzers, 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.

APx users can import and analyze WAV audio files using an acquisition saved by a contract manufacturer's audio analyzer 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.

APx can now generate the lossless Dolby True HD 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, for example allowing AP2700 or ATS files to serve as pass/fail limits.

APx500 v2.5 works with any model of APx audio analyzer. It is a free upgrade for APx users and is available from
