By designating a file as "exclusive," the audio processing community implicitly agrees on a —much like the "Lenna" image in computer vision or the "Asterix" font in typography. It is primarily used as a canonical "clean"
The file is a standard sample audio file provided within the MATLAB Audio Toolbox . It is primarily used as a canonical "clean" reference signal in educational tutorials and documentation for signal processing tasks such as speech denoising , beamforming , and feature extraction .
