Which sample rates are supported?

Any positive integer sample rate is accepted. Common presets (44100, 48000, 88200, 96000, 176400, 192000 Hz) are provided for convenience, but you can type any value.

Why are sample counts rounded to whole numbers?

Samples are discrete integers — a DAW cannot play a fractional sample. The tool rounds to the nearest integer, which is the standard approach used by every major DAW.

What is a quarter note in samples?

A quarter note equals one beat, so its sample count is (60 / BPM) × sample rate. At 120 BPM and 44100 Hz that is exactly 22050 samples.

Does a dotted or triplet note duration change the result?

This tool covers straight note values only. A dotted note is 1.5× the straight value; a triplet is 2/3 of it. Multiply the displayed sample count accordingly.

Can I use this for time-stretching calculations?

Yes. If you know the original tempo and target tempo, calculate the sample count for the same note duration at both tempos — the ratio gives you the stretch factor.

Is there a limit on BPM input?

The tool accepts 1–999 BPM. Values outside that range show an inline error because note durations become impractically long or impossibly short.

Summary

The Tempo to Samples Converter translates musical tempo (BPM) into exact sample counts for any note duration at your chosen sample rate. It covers whole, half, quarter, eighth, and sixteenth notes, and also shows millisecond equivalents so you can cross-check with delay plug-ins. All calculations happen instantly in your browser with no data sent anywhere.

How it works

Enter your project tempo in BPM (beats per minute).
Select or type your DAW sample rate (e.g. 44100, 48000, 96000 Hz).
The tool calculates the duration of one beat in seconds: 60 / BPM.
Each note duration is derived as a fraction of the beat — e.g. a whole note is 4 beats.
Sample counts are computed by multiplying seconds by the sample rate and rounding to the nearest integer.
Copy any value with one click to paste directly into your sampler or delay plugin.

Use cases

Set a delay plug-in feedback loop to exact note-length sample offsets.
Program a hardware sampler that accepts loop-length in samples.
Sync granular synthesis grain size to the project BPM.
Validate or debug beat-synced audio buffer sizes in code.
Calculate reverb pre-delay in samples to match a song grid.
Match LFO cycle lengths in a modular synth to BPM-locked note values.
Confirm exported audio loops are trimmed to the correct sample count.
Quickly convert between BPM and sample offsets without opening a DAW.
