SOUND SYNTHESIS

摘要

A device (1) for synthesizing sound comprising sinusoidal components comprises selection means (2) for selecting a limited number of sinusoidal components from each of a number of frequency bands (41) using a perceptual relevance value, and synthesizing means (3) for synthesizing the selected sinusoidal components only. The frequency bands may be ERB based. The perceptual relevance value may involve the amplitude of the respective sinusoidal component, and/or the envelope of the respective channel.
