WebSep 24, 2024 · To approximate the white noise's PSD behavior, you can resort to N-oversampling, increasing the sampling and Nyquist frequency to N·44.1KHz: you spread each value of sound sampled at 44.1KHz among adjacent N samples of a new (N·sample_count)-sized vector (array) of noised samples and add uniform noise. http://ece-research.unm.edu/bsanthan/ece539/white2.pdf

WebAug 15, 2016 · [White] Just like the white colour which is composed of all frequencies in the visible spectrum, white noise refers to the idea that it has uniform power across the whole frequency band. As a consequence, the Power Spectral Density (PSD) of white noise is constant for all frequencies ranging from −∞ − ∞ to +∞ + ∞, as shown in Figure below.
