temporalcentroid​

temporalcentroid() -> llll

Generates audio descriptor to calculate the temporal centroid of a buffer, defined as the point in time that is a temporal balancing point of the sound's energy. See analyze.

The resulting buffer will be updated with the following keys:

  • temporalcentroid
info

temporalcentroid is a mirror implementation of the same algorithm in the Essentia library. For more details on the algorithm, please check the Essentia Algorithms reference.

Output​

temporalcentroid descriptor [llll]

Usage​

temporalcentroid is meant to be used with the analyze function:

$buffer = importaudio('singing.wav'); ## input buffer
$descr = temporalcentroid(); ## generate temporalcentroid audio descriptor
$buffer.inspect('before analysis');
$buffer = $buffer.analyze($descr); ## apply analysis
$buffer.inspect('after analysis')
