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.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 4)

In this article series, Stuart Yaniger examines ways to create a low-cost system for lab-grade audio electronics measurements. The pieces of a powerful modern measurement system comprise a sound card, software, and a signal conditioning interface and, of course, the right computer. In this fourth article in the series, the author looks at selecting the right interface. This article was originally published in audioXpress, September 2015.

Practical Test & Measurement: Sound Cards for Data Acquisition in Audio Measurements (Part 3)

In this article series, Stuart Yaniger examines ways to create a low-cost system for lab-grade audio electronics measurements. The pieces of a powerful modern measurement system comprise a sound card, software, and a signal conditioning interface and, of course, the right computer. That’s where Yaniger delves in this third part, also sharing some of his first findings on available software. This article was originally published in audioXpress, August 2015.

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.

A Versatile Line Amp for Preamp, Headphone, and Power Use

Here’s a do-it-yourselfer’s dream in tube amp design: four operating modes, high quality, low cost, and low distortion. An article originally published by audioXpress in May 2007. A true versatile project which we think deserves to be shared.

Extend the useful life of those precious tubes: use a Tube Amplifier High-Voltage Delay

Extend the useful life of those precious tubes: use a Tube Amplifier High-Voltage Delay

Tube life can be extended if you delay the application of high voltage until after the heaters have warmed up and current can flow. This little module does just that: depending on the setting of a jumper, it delays the high-voltage for 40 or 60 seconds after the amplifier is switched on. And the module is available as a kit. This article was originally published in audioXpress, February 2014.
