librosa.util.match_intervals¶

librosa.util.match_intervals(intervals_from, intervals_to)[source]¶

Match one set of time intervals to another.

This can be useful for tasks such as mapping beat timings to segments.

Note

A target interval may be matched to multiple source intervals.

Parameters:	intervals_from : np.ndarray [shape=(n, 2)] The time range for source intervals. The i th interval spans time intervals_from[i, 0] to intervals_from[i, 1]. intervals_from[0, 0] should be 0, intervals_from[-1, 1] should be the track duration. intervals_to : np.ndarray [shape=(m, 2)] Analogous to intervals_from.
Returns:	interval_mapping : np.ndarray [shape=(n,)] For each interval in intervals_from, the corresponding interval in intervals_to.
Raises:	ParameterError If either array of input intervals is not the correct shape
