Sound Effects Processing and Manipulation with Wavelet Packet Transform

It is proposed a new method for more realistic and less repetitive sound effects for video games. Preserving the main characteristics of the sound, the method synthesizes and manipulates sound based on the wavelet packet transform of the signal. The coefficients of the transform can be used for manipulations in the frequency and temporal spectra, leading to different sounds. They can also be shuffled in time in a continuous synthesis, creating a continuous sound texture.
