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.

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.

June 2015 is – we have to say it – undoubtedly one of the most diverse and interesting issues we have put together. The magazine has something for everyone and lots of great content we are certain will be greatly appreciated by our community.
