AP adds HDMI to its audio analysers to benefit designers of smart phones and set-top boxes
Audio Precision
HDMI I/O option for Ax525
The HDMI I/O test option for Audio Precision’s APx525 range of two- and four-channel audio analysers is aimed at designers and manufacturers of smart phones, set-top boxes and tablet computers.
Previously available only for the eight-channel APx585, this HDMI configuration allows engineers to measure HDMI audio quality and audio format, with the APx metadata recorder alerting the user when a source’s EDID doesn’t match the audio format being received by the analyser.
All standard audio measurements are available and users are able to verify the bit accuracy of bitstream mode (even for lossy codecs), as well as arbitrarily edit APx’s source EDID, to test a sink’s error-handling capacity.
In addition to generating linear/PCM audio streams, APx can stream lossless formats, such as Dolby TrueHD,and compressed formats, such as Dolby Digital and dts Digital Surround, from pre-encoded audio test files.
