Audio Analyzer Keeps Contract Manufacturers Honest
"An approach that has been growing in popularity is to contractually bind the manufacturer to test the product in a specified manner using equipment supplied by the OEM. And this is the thinking behind Audio Precision’s introduction of its APx515 "

Pro Audio Asia

APx515 Production Test Audio Analyzer
"Because APx515 can perform a more comprehensive evaluation on more units per hour than a simple distortion analyser, a production line’s defect rate is reduced and the test station doesn’t cause a bottleneck."

EE Times

Audio analyzer optimized for production test
" A high speed test option enables the APx515 to make all the key audio measurements in less than three seconds..."

Electronics World

Testing RDS-equipped FM Radio Receivers 
"Testing FM receivers is not that much different from testing other pieces of audio equipment, but in practice...."

Chip Design

The 5 Minute Guide to Chip Level Audio Test
"Test all the sample rates and modes the device is supposed to work at. Just because it works in one mode doesn’t mean the others will be OK."

T&M World

How New Products Challenge Audio Test 
"Consumer devices have embraced HDMI as a virtual standard interface. We’ve gotten heavily involved not so much in testing the HDMI interface itself, but in analyzing how audio passes through the interface."

Pro Sound News Europe

Will everything Behringer touches turn to gold?
"The mixer and electronic testing is very comprehensive, with Audio Precision machines on every input and output. And with a staggering 150 of them in the EuroTec plant, the commitment to quality cannot be underestimated."

Electronics World

The 7-Point Path to Better Spec Writing
"Dave Mathew looks at the importance of specifications, explains why we all need to take much greater care over their preparation and use and gives some guidance."

T&M World

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."

T&M World

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."

Pro Audio Review

Audio Precision APx Audio Analyzers [Audio Analyzer review]
"The APx measurement software is fast, effective, and full-featured. It’s easy to use for a novice without at all being tedious for a power user... The stuff geek dreams are made of."

 

2009

EE Times 

How to measure audio quality in portable media players " Several useful training videos on the proper test and measurement set up for audio quality in portable media devices have been produced by Cirrus Logic using a SYS-2722."

TV Technology 

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."

Radio World 

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." 

Electronics Product Design

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. "

EE Asia

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."

EDN

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."

Audioholics

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!"

PSNE

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."

PSNE

25 Years of being precise [PDF Pg. 38]
"Grounding is everything. And that’s as true in life as it is in electrical engineering!”

Electronic Design

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 hardware shouldn’t be considered a replacement for proper product testing programs."

Electronic Design

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.

Broadcast Engineering

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."
