Why The Fourier Transform
Natural for
visualizing
audio
signals
:
The
ear
performs a kind of
Fourier analysis
Spectral models can be very compact and flexible:
MPEG
audio coding
Sinusoidal modeling
(``
additive synthesis
'')
Sparse modeling elements for
Machine listening
Music Information Retrieval
(MIR)
AES talk
on some history of audio spectral modeling at
CCRMA
and elsewhere.
Any
Linear Time Invariant
(
LTI
) system can be implemented in the
frequency domain
by means of the
Fourier Transform
(``
FFT
convolution
'')
