inharmonicity​

inharmonicity(
    @mode 0
) -> llll

Generates an audio descriptor to calculate the inharmonicity of a buffer.

The resulting buffer will be updated with the following keys:

  • inharmonicity
info

inharmonicity 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: Global
    • 1: Time series
    • 2: Time-tagged time series
    • 3: Buffer

Output​

Inharmonicity descriptor [llll]

Usage​

inharmonicity is meant to be used with the analyze function:

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