What is the formula for converting samples to time?

Time (seconds) = Number of Samples / Sample Rate (Hz). For milliseconds multiply by 1000; for microseconds multiply by 1,000,000.

What is the formula for converting time to samples?

Samples = Time (seconds) × Sample Rate (Hz). Non-integer results are displayed as both the exact float and the nearest integer.

What sample rates are supported?

Any positive value in Hz is supported. Common presets (8000, 11025, 22050, 44100, 48000, 88200, 96000, 176400, 192000 Hz) are one click away; you can also type a custom rate.

Why does the sample count come out as a decimal?

When converting from time, the sample count is Time × Sample Rate. If the time does not align perfectly to a sample boundary, the result is fractional. In practice you round to the nearest integer; the tool shows both the exact and rounded values.

How do I find the latency of an audio buffer in ms?

Set direction to "Samples → Time", enter the buffer size (e.g. 512) as the sample count, and choose your sample rate (e.g. 44100 Hz). The result in milliseconds is your buffer latency — 512 / 44100 ≈ 11.61 ms.

Does this tool work for video frame rates or MIDI ticks?

The math is the same for any discrete count divided by a rate. For video you would enter the frame number and frame rate (e.g. 24 fps). For MIDI ticks you would enter tick count and ticks-per-second. The tool accepts any positive rate.

Summary

This tool converts between audio sample count and time duration using the relationship: time (s) = samples / sample rate. Enter a sample count to get the duration in seconds, milliseconds, and microseconds; or enter a time value to get the exact sample count. Supports any sample rate — standard rates (8 kHz to 192 kHz) are available as presets, or you can type a custom value.

How it works

Select a direction: samples-to-time or time-to-samples.
Pick a sample rate from the presets or type a custom value in Hz.
Enter the sample count or the time duration depending on the chosen direction.
The converter applies time = samples / sample_rate (or its inverse) and displays results in multiple units.
Results update instantly as you type.
