Abstract
Systems (or) and methods (or) are provided for selecting a post-compression waveform from a post-compression waveform table () and supplying it to a synthesis engine (). The post-compression waveform is based upon a set of post-compression coefficients determined by generating a frequency-domain representation of a periodic signal, the representation including at least one pre-compression frequency-domain sample (), and performing a threshold-based compression of the pre-compression frequency-domain samples. Systems and methods also include indexing and storing () post-compression coefficients in a post-compression coefficient table (), generating () a post-compression waveform based upon the set of post-compression coefficients, and placing () the post-compression waveform in the table prior to the selecting (). The system and method also include performing () a read-ahead operation on a sound file before selecting the post-compression waveform, the read-ahead operation indicating the post-compression waveform to be selected and supplied to the synthesis engine.
