| Abstract | In this paper we evaluate some of the alternative methods commonly
applied in the first stages of the signal processing chain of
automatic melody extraction systems. Namely, the first two stages
are studied – the extraction of sinusoidal components and the computation
of a time-pitch salience function, with the goal of determining
the benefits and caveats of each approach under the specific
context of predominant melody estimation. The approaches
are evaluated on a data-set of polyphonic music containing several
musical genres with different singing/playing styles, using metrics
specifically designed for measuring the usefulness of each step for
melody extraction. The results suggest that equal loudness filtering
and frequency/amplitude correction methods provide significant
improvements, whilst using a multi-resolution spectral transform
results in only a marginal improvement compared to the standard
STFT. The effect of key parameters in the computation of the
salience function is also studied and discussed.
