Abstract:
1. A method of synthesizing a signal comprising sinusoids from encoded data, the encoded data comprising, for each of a plurality of consecutive time segments, one or more frequency values (f) representing sinusoids, and data identifying times of occurrence of transients, the method comprising the steps of: generating sinusoids with each of the one or more frequency values (f), and linking sinusoids across a plurality of consecutive segments; identifying sinusoidal segments corresponding to segments in the encoded data containing transients using said data identifying times of occurrence of transients; weighting sinusoidal segments, corresponding to encoded data segments with no transients, with a normal window (W weighting sinusoidal segments, corresponding to encoded data segments in which the time of occurrence of a transient is identified, with a first modified window (W
