Abstract: A computer-implemented method for digital processing is provided. A set of tristimulus values representing a first color in a color space are received. A first representation of a first spectral curve corresponding to the first color is determined, where the first spectral curve is within a gamut of solid reflectances. A second representation of a second spectral curve corresponding to the first color is determined where the second spectral curve contains at least one reflectance wavelength outside the gamut of solid reflectances. Based on selection criteria, the first representation or the second representation is selected. The selected representation is then applied during digital processing.

Abstract: A flexible apparatus for, and method of, acoustically improving an environment permits manual adjustment by one or more local or remote users using a simple graphical interface and automatic adjustment of the system parameters once the manual adjustment is performed. The inputs are weighted by distance from the physical apparatus. The apparatus includes a receiver, a converter, an analyser, a processor and a sound generator. The acoustic energy impinges on the receiver and is converted to an electrical signal by the converter. The analyser receives the electrical signal from the receiver, analyzes the electrical signal, and generates data analysis signals in response to the analyzed electrical signal. The processor produces sound signals based on the data analysis signals from the analyser in each critical band. The sound generator provides sound based on the sound signals. This permits the users to define the sound heard in a set space.
