Title:
音声パラメータの復号化
Document Type and Number:
Japanese Patent JP2009543112
Kind Code:
A
Abstract:
A device (1) for producing sound samples from sound parameters representing sound components comprises a transient synthesis unit (14) for synthesizing transient sound components from transient sound parameters contained in each frame. To increase the efficiency of the synthesis, a transient selection unit (11) is arranged for selecting only a single transient sound component per frame. Additionally, the device may be arranged for producing fewer sinusoidal sound components if a transient is produced. Transform domain coefficients may be convolved with a transform domain representation of a time window representation, the number of resulting transform domain coefficients being controlled to further enhance the efficiency of the synthesis.
