librosa.samples_to_time(samples, *, sr=22050)[source]

Convert sample indices to time (in seconds).

Parameters:

samplesnp.ndarray: Sample index or array of sample indices
srnumber > 0: Sampling rate

Returns:

timesnp.ndarray [shape=samples.shape]: Time values corresponding to samples (in seconds)
