spectralkurtosis
spectralkurtosis(
@mode 0
) -> llll
Generates an audio descriptor to compute the spectral kurtosis of a buffer.
The resulting buffer will be updated with the following keys:
spectralkurtosis
info
spectralkurtosis
is a mirror implementation of the same algorithm in the Essentia library.
For more details on the algorithm, please check the Essentia Algorithms reference.
Arguments
@mode
[int]: Analysis mode. (default:0
).0
: Global1
: Time series2
: Time-tagged time series
Output
Spectralkurtosis descriptor [llll]
Usage
spectralkurtosis
is meant to be used with the analyze
function:
$buffer = importaudio('singing.wav'); ## input buffer
$descr = spectralkurtosis(); ## generate spectralkurtosis audio descriptor
$buffer.view('before analysis');
$buffer = $buffer.analyze($descr); ## apply analysis
$buffer.view('after analysis')
