Audio Precision Gets Smart In Stereo: Hdmi Available On 2-channel Analyzers Ap Adds Hdmi To Apx525

The APx HDMI option allows engineers to measure HDMI audio quality and audio format. All standard audio measurements are available or users can verify bit accuracy of bitstream mode, even for lossy codecs. The APx metadata recorder alerts the user when a source’s EDID doesn’t match the audio format being received by the analyzer. Conversely, users can arbitrarily edit APx’s source EDID to test a sink’s error-handling capability. In addition to generating linear / PCM audio streams, APx can stream lossless formats (such Dolby TrueHD™ or dts-HD Master Audio™) and compressed formats (such as Dolby Digital™ and dts Digital Surround™) from pre-encoded audio test files.

“APx’s advanced HDMI testing capability has been fundamental to the improvement of A/V receiver design over the past four years,” said Tom Williams, VP of Sales and Marketing at Audio Precision. “Now HDMI is becoming standard on a new class of audio devices, consumers expect high-definition performance. An APx525 with HDMI, Bluetooth, and the Digital Serial interface gives smartphone and set-top box designers everything they need to meet the challenge.”
