Samples and milliseconds

Convert a sample count into time, or a time offset into samples, at the exact sample rate you select.

Converted valueEnter values to calculate

The sample rate is the conversion factor

At 48 kHz, 48 samples last 1 millisecond and 48,000 samples last 1 second. At 44.1 kHz, the same sample count represents a different duration.

Fractional sample results

A requested time may fall between discrete samples. The calculator shows the exact result and the nearest whole sample so you can match the precision your editor accepts.
