Virtual trumpet
reconstruction
nThe impulse response (mouthpiece -> radiated
field) characterizing different
instruments are measured
nA music piece is played on one instrument, and
recorded in anechoic
environment
nThe impulse
response of this instrument is inverted
nThe anechoic
recording is deconvolved by convolution with the inverse filter
nThe deconvolved recording is used as the
starting point for subsequent
reconvolutions with the IRs of the different instruments
