Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 7) - Pitting the CLIO Pocket Against a Sound Card

In this article of a series on how to create a low-cost system for lab-grade audio electronics measurements, Stuart Yaniger decided to do a comparison experiment between a dedicated but very affordable measurement solution - the Audiomatica CLIO Pocket - and its own sound-card based system described previously. This article was originally published in audioXpress, December 2015.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 6) - Measurement Examples

Stuart Yaniger continues to examine ways to create a low-cost system for lab-grade audio electronics measurements. In this article, a few measurement examples are used to illustrate the power and the versatility of sound-card-based measurements. To illustrate the usefulness of measurements in the design process, Yaniger also explores the effects of load on power supply noise for a common IC regulator circuit. This article was originally published in audioXpress, November 2015.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 5) - The User

In this article series, Stuart Yaniger examines ways to create a low-cost system for lab-grade audio electronics measurements. The first four articles in the series looked at the hardware and software bits of the sound-card based measurement system. The last remaining piece is the user and the need to choose the right measurement parameters. This article was originally published in audioXpress, October 2015.

Driven by Function: Vanatoo Transparent Zero Wireless Powered Speakers

Recently introduced at AXPONA 2017, the new Vanatoo Transparent Zero active speakers ($299.00 /pair) have caused quite a stir at the Chicago show. Not only for the extremely affordable price but for its "convincing punch, far out of its weight class," as audioXpress author Stuart Yaniger noted. Assuming a daring approach to their designs, the Vanatoo Transparent Zero active speakers feature built-in analog and digital inputs, Bluetooth wireless with aptX and USB, providing a convincing all-in-one solution.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 2)

In this article series, Stuart Yaniger looks at some of the available options and methods to create a low-cost system (emphasis on “low-cost”) for lab-grade audio electronics measurements and provides some examples. In this second part, Yaniger starts by examining sound card requirements and the criteria to decide what features to look for in a sound card targeted for audio measurement. This article was originally published in audioXpress, July 2015.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements

Part 1 of an article series that looks at some of the available options and methods to create a low-cost system (emphasis on “low-cost”) for lab-grade audio electronics measurements. Focusing on solutions within easy reach of budget-conscience hobbyists, the goal is to demonstrate how you can generate useful data, similar to the graphs and charts in the audio review magazines, but without the expense. A great test and measurement article series by Stuart Yaniger, which started to be originally published in audioXpress, June 2015.

Fresh From The Bench: Audio Precision APx1701 Transducer Interface

audioXpress March 2017 featured a thorough review by Stuart Yaniger of Audio Precision’s new APx1701 Transducer Interface. This compact solution, when combined with an APx500-series analyzer, creates a test center suitable for measuring speakers, headphones, and microphones, as well as electronics. As Stuart Yaniger finds out, the combination of the APx1701, an APx515 and APx500 software, provides an extremely comprehensive and convenient multi-functional measurement test center.
