The Lab Bench of 2021: Virtins Multi Instrument Measurement Software

Stuart Yaniger shares his more recent experiences with Virtins Multi Instrument Measurement Software, which he combined with his RME ADI-2 Pro FS R audio interface and the Linear Audio Autoranger II to create what he defines as the Lab Bench of 2021. This is a very complete solution for anyone working on product testing and evaluation from home. It is also an approach that complements Yaniger's 2015 series of audioXpress articles on how to adapt home computers and sound cards for audio test and measurement. In this article, he experiments and updates his findings about Virtin's Multi Instrument software. This article was originally published in audioXpress, March 2021.
