Testing the Pro's Audio
"[QSC] plans to replace the current Audio Precision System One audio analyzer with an APx585 model that has an oscilloscope integrated into its application software.... Somarel expects at least a 50% reduction in test time with the new test station."

Best in Test Finalists 2010: Audio/video and multimedia
"With the BW52, audio engineers can use one instrument to measure audio and out-of-band noise at significantly greater resolution. As a result, audio design can improve at a lower cost of development."

Audio Precision ATS-2 [Audio Analyzer review]
"I take my hat off to the AP engineering staff for providing the industry with such a valuable and useful tool. In my estimation, ATS-2 is the perfect combination of power and simplicity." |

TDF Upgrades Signal for New Age
"Our old analyzers took 30 seconds to run the test, whereas the ATS-2, with its HIgh Speed Testing option, can do it all in 1 second." |

Improved analysers using Log-Swept sine techniques
"Chirp-based testing, on the other hand generates the whole response and is relatively fast — on AP's eight-channel APx585 analyser, 14 measurements are computed from one chirp signal being fired into the equipment under test. " |

Perform systematic testing of HDMI EDID
"But just reading the EDID
isn’t enough; the engineer also
needs to test the device’s ability
to cope with the media formats
that the onboard EDID says it can
handle.
It’s simply a matter of constructing
a systematic test program." |

Software upgrade brings logic-analyzer-style insights to audio testing
" Errors in metadata can cause real problems in HDMI that you just don't see in S/PDIF, a logic-analyzer view shows exactly what’s going on over time so you can identify what’s causing glitches or other issues." |

APx585 Audio Analyzer to Revolutionize A/V Measurements [Audio Analyzer review]
" AP has burst onto the scene with the easiest Audio Analyzer to use but they took it up a notch by also making it the most powerful. I’ve got my cake and I am eating it too!" |

Loudspeaker testing the affordable way [PDF Pg. 28]
"While anechoic chambers will never
die out completely, they can now be dispensed
with for all but the most
demanding of acoustic test applications,
simplifying loudspeaker and microphone
testing." |

"Grounding is everything.
And that’s as true in life as it is in electrical engineering!” |

What Was That Noise?
"If you're really going to measure real-world rejection of "commonmode" signals, your test practices must take those impedance-match imbalances and their effects into account." |
IBE |
Towards better EDID & HDMI
There's sense in using PlugFests, but a few ad hoc interconnection tests performed on some pre-production hardward shouldn't be considered a replacement for proper product testing programs." |

Avoid The Pitfalls Of Inaccurate EDID
Modern A/V devices rely on HDMI Extended Display Identification Data (EDID) to communicate with other devices in an audio/video system. If the EDID is poorly thought out at the design stage, significant audio and video errors can occur. |

Testing audio consoles
"Only comprehensive testing can ensure the high degree of reliability that is essential to avoid costly downtime and maintain delivery of high-quality audio." |
