摘要： A sound decoding device (1) is arranged for decoding sound represented by sets of parameters, each set comprising sinusoidal parameters (SP) representing sinusoidal components of the sound and further parameters (NP, TP) representing further components of the sound, such as noise and/or transients. The device comprises a separate sinusoids generator unit (17, 18) for each output channel (L, R), while the further component generator units (20; 21) are shared between the channels.

摘要： A device for synthesizing sound having sinusoidal components includes a selector for selecting a limited number of the sinusoidal components from each of a number of frequency bands using a perceptual relevance value. The device further includes a synthesizer 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.

摘要： A device (1) is arranged for synthesizing sound represented by sets of parameters, each set comprising noise parameters (NP) representing noise components of the sound and optionally also other parameters representing other components, such as transients and sinusoids. Each set of parameters may correspond with a sound channel, such as a MIDI voice. In order to reduce the computational load, the device comprises a selection unit (2) for selecting a limited number of sets from the total number of sets on the basis of a perceptual relevance value, such as the amplitude or energy. The device further comprises a synthesizing unit (3) for synthesizing the noise components using the noise parameters of the selected sets only.
