espnet2.fileio.segments.seconds_to_sample(seconds: float, rate: int) → int

Index of the first sample at or after seconds, cut as Kaldi segments are.

The index is floor(seconds * rate), the truncation int() gives for non-negative times, except that a product just below a whole number because of float error counts as that number: 0.2559375 s at 16 kHz is sample 4095, where int(0.2559375 * 16000) gives 4094. Times before 0 map to sample 0.

Examples

>>> seconds_to_sample(0.2559375, 16000)
4095
>>> seconds_to_sample(1.0, 16000)
16000
