GPiO Audio Measurement Toolbox
Measuring performance of audio components like microphones, speakers, converters, and amplifiers can be a difficult task. In this post, I’ll talk about some of the tools I use to make this job easier. Analyzers, reference transducers, calibrators, meters, and more come with various feature sets and price tags. The items below just happen to be my favorites.
Soundcheck (Listen Inc.): Soundcheck is a versatile audio analyzer that I’ve used for years in both R&D and production line environments. It’s built in a “modular” way, so you buy the features that you need. What I love about this software is the customization potential in everything from the granularity of frequency points in a sine sweep to the ability to post process measurements in a sequence automatically based on macros. Soundcheck is not cheap, but it saves me tons of time when I need to measure and report on audio components or subsystems.
