13. November 2017 Let’s Clear Up Some Things About Sweeps… Sweeps are a popular method in the field of audio measurement to describe the change in a measured output value over a progressing input parameter. The most commonly-used progressive input parameter is frequency varied over the standard audio bandwidth of 20 Hz to 20 kHz. But there is much more to a sweep. This article provides an overview as well as detailed explanations of various methods, parameters and optimizations concerning sweeps. Read more
