AB  - Logarithmic chirp signals, also known as exponentially swept sines, have been used to determine the behavior of audio systems for more than two decades. This is done using a nonlinear deconvolution process that evaluates the direct and harmonic responses of a system. Despite the long history of this technique, improvements continue to be discovered and questions remain. Relatively subtle features of these signals are important for making accurate measurements. This paper describes how these signals have been used in measuring audio systems, describes the current state of the art, and clarifies the theoretical foundations and limitations of the technique.
