Convert samples to ms at any sample rate, such as 44.1 or 48 kHz, or milliseconds to samples, and find the sample rate from samples and duration.

Count per channel (audio frames), not interleaved values from all channels.

Default 44,100 Hz (CD audio); 48 kHz is common for video. Pick from the list or type your own.

Samples To ms Formula

The following formula is used to calculate the conversion of samples to milliseconds.

MS = (S / SR) × 1000

Variables:

  • MS is the duration in milliseconds (ms)
  • S is the number of audio samples
  • SR is the per-channel sample rate in hertz (Hz, samples per second)

To calculate block duration in milliseconds, divide the per-channel sample count (audio frames) by the sample rate in Hz, then multiply by 1000. If the rate is entered numerically in kHz instead, milliseconds = samples ÷ rate in kHz. The reverse formulas are samples = milliseconds × rate in Hz ÷ 1000 and rate in Hz = samples × 1000 ÷ milliseconds. Fractional sample equivalents are timing positions; the calculator also shows the nearest whole sample count and its resulting duration. Zero count and zero duration do not determine a unique sample rate.

What Does “Samples to ms” Mean?

Samples To ms (Milliseconds) is a conversion metric used in digital audio processing. It refers to the conversion of the number of audio samples to the equivalent duration in milliseconds. This is important in audio editing and production as it helps in precise timing and synchronization of audio elements. The conversion rate depends on the sample rate of the audio file, which is typically 44.1 kHz or 48 kHz in professional audio production.
