carat.features.feature_time_quantize

carat.features.feature_time_quantize(feature, time, tatums, window=0.1)

Time quantization of the feature signal to a tatum grid.

The feature signal is time-quantized to the rhythm metric structure by considering a grid of tatum pulses equally distributed within the tactus beats. The feature value assigned to each tatum time instant is obtained as the maximum value of the feature signal within a certain window centered at the tatum time instant. Default value for the total window lenght is 100 ms.

Args:

• feature (numpy array): feature signal values
• time (numpy array): time instants of the feature values
• tatums (numpy array): time instants of the tatum grid

Returns:

• :

Raises:

• quantized_feature (numpy array): time quantized feature signal values
