Abstract
In this chapter we draw links between the widely
used gammatone
filter auditory model and wavelet theory. From
the viewpoint of
wavelet theory the benefit from linking these
research fields is a fast
method for the computation of a time-scale representation.
From
the viewpoint of auditory filtering the benefits
are the existence of
methods for the detection of signal singularities
and for resynthesis.
Our methods has proved to be useful for the analysis
of music pieces
with a limited spectral overlap of the different
signal components.
It has been implemented for further research
in automated music
transcription and auditory source separation,
but might also be of
interest for sound synthesis systems based on
the analysis and
transformation of acoustic signals.
