Convert sample frames to milliseconds and milliseconds back to frames at 44.1, 48, 96 or any custom sample rate from 1–768 kHz.
For 10 ms at 48,000 Hz, enter:
The nearest whole frame minimizes the timing difference. Halfway values round to the higher frame count.
Use this as the offset magnitude. Choose whether to advance or delay the audio in your DAW. A shorter duration does not by itself tell you which direction to move a track.
A sample frame is one simultaneous sample position across all channels. The selected sample rate counts frames per second, so channel count does not change timing.
At a sample rate of R frames per second, frames to ms equals frames divided by R, multiplied by 1,000. For milliseconds to frames, multiply milliseconds by R and divide by 1,000. At 48 kHz, one millisecond is 48 frames and 512 frames is 10.666667 ms.
milliseconds = sample frames ÷ sample rate × 1,000; sample frames = milliseconds × sample rate ÷ 1,000
Select the sample rate used by your audio interface, DAW session or file.
Enter a sample-frame count to translate plugin latency, buffer size or phase offset into milliseconds.
Enter milliseconds to find the equivalent frame offset, then use the nearest whole frame when required.
Use the whole-sample setting to see the actual duration and rounding difference, then copy the frame count into your DAW's sample-offset control.
At 48,000 sample frames per second, 512 frames last 10.666667 milliseconds. In reverse, 10 milliseconds at 48 kHz equals exactly 480 frames.
Review BeatTiming's calculation accuracy, precision and release-testing methodology.
Common buffer sizes have different durations at different sample rates. For example, 2,048 sample frames is 46.439909 ms at 44.1 kHz, 42.666667 ms at 48 kHz and 21.333333 ms at 96 kHz.
To turn a measured timing offset into a DAW setting, select the session's sample rate and enter the offset magnitude in the Milliseconds field. The whole-sample setting beneath the results gives the nearest integer frame count, its actual duration and the remaining timing difference. Copy the frame count when the control expects samples; use milliseconds directly when that is the control's unit.
For example, 1 ms at 44.1 kHz is 44.1 frames. The nearest whole-frame setting is 44 frames, approximately 0.997732426304 ms, so the offset is about 2.267574 microseconds shorter. At 48 kHz, 1 ms is exactly 48 frames and the rounding difference is zero. The session's sample rate therefore matters even when the requested time is unchanged.
Whole-frame choices and the sign of the timing difference are computed from the entered decimal value before display rounding. Durations and microsecond differences are displayed as rounded decimals. Exactly halfway values choose the higher frame count; advance-versus-delay direction is a separate choice in your audio software.

At 48 kHz, 512 frames is 10.666667 ms. At 44.1 kHz, the same 512 frames is about 11.609977 ms.
There are 48 frames per millisecond at 48 kHz and 44.1 frames per millisecond at 44.1 kHz.
Multiply milliseconds by the sample rate, then divide by 1,000. At 48 kHz, 10 ms equals exactly 480 frames.
No. Stereo doubles the number of stored sample values, but both channels play together, so the duration stays the same.
Physical sample-frame positions are whole numbers. If a device or DAW requires an integer, use the displayed nearest whole-frame value.
One millisecond is 44.1 sample frames at 44.1 kHz. A whole-sample control can use 44 frames, which lasts approximately 0.997732426304 ms: about 2.267574 microseconds shorter than requested. The calculator shows this difference and lets you copy the integer frame count.
No. The rounding difference compares two durations. Choose whether to advance or delay the audio based on the alignment you need and your DAW's sign convention. This calculator supplies the non-negative offset magnitude.
