LibXtract is a simple, portable, lightweight library of audio feature
25
extraction functions. The purpose of the library is to provide a
26
relatively exhaustive set of feature extraction primatives that are
27
designed to be 'cascaded' to create a extraction hierarchies.
28
​
29
For example, 'variance', 'average deviation', 'skewness' and
30
'kurtosis', all require the 'mean' of the input vector to be
31
precomputed. However, rather than compute the 'mean' 'inside' each
32
function, it is expected that the 'mean' will be passed in as an
33
argument. This means that if the user wishes to use all of these
34
features, the mean is calculated only once, and then passed to any
35
functions that require it.
36
​
37
This philosophy of 'cascading' features is followed throughout the
38
library, for example with features that operate on the magnitude
39
spectrum of a signal vector (e.g. 'irregularity'), the magnitude
40
spectrum is not calculated 'inside' the respective function, instead,
41
a pointer to the first element in an array containing the magnitude
42
spectrum is passed in as an argument.
43
​
44
Hopefully this not only makes the library more efficient when
45
computing large numbers of features, but also makes it more flexible
46
because extraction functions can be combined arbitrarily (one can
47
take the irregularility of the Mel Frequency Cepstral Coefficients
48
for example).
