Abstract
Official abstract text for this publication.
Systems and method for performing adaptive audio signal processing using music as a measurement stimulus signal. A musical stimuli generator may be used to generate musical stimulus signals composed to provide a stimulus with a spectrum that is substantially dense, and ideally white or pink, over a selected frequency range, so that all frequencies of interest are stimulated. The musical stimuli generator may generate melodically pleasing musical stimulus signals using music clips that include any of: a chromatic sequence, a chromatic sequence including chromatic tones over a plurality of octaves, a chromatic sequence including chromatic tones over a selected plurality of octaves, or an algorithmically composed chromatic sequence, to cover a selected frequency range. The musical stimulus signal may be generated as sound into the environment of use. An audio input picks up the sound from the environment, and a sound processor uses the received musical stimulus signal to determine a transfer function.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for measuring a response to an audio signal in an environment of use for an audio system comprising: generating a musical stimulus signal composed to provide a spectrally dense stimulus over a selected frequency range; generating a musical sound from the musical stimulus signal in the environment of use; receiving the musical sound at an audio input in the environment of use; and using the received musical sound to calculate a transfer functio…
