Appeal No. 2002-0810
Application No. 09/014,871
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
Claim 1. A method for generating a synthesized sound,
comprising:
a) obtaining a wavelet representation of a first sound
according to:
i) determining a characteristic shape of the first
sound by inspecting the first sound at each of a plurality of
scales;
ii) comparing the characteristic shape with each of a
plurality of wavelet types;
iii) selecting the wavelet type from the plurality of
wavelet types that most closely matches the characteristic shape;
iv) obtaining a wavelet representation of the first
sound using a wavelet transform of the first sound based on the
selected wavelet type;
b) obtaining a plurality of parameters which characterize
the wavelet representation; and
c) generating the synthesized sound by varying at least some
of the plurality of parameters.
