What is a sample-accurate edit point?

In digital audio every moment in time corresponds to a discrete sample number — for example, at 44100 Hz there are 44,100 samples every second. A sample-accurate edit point is a cut or splice position defined by an exact sample index rather than an approximate frame or millisecond value, eliminating any rounding drift.

Which sample rates are supported?

The calculator includes presets for 22050, 44100, 48000, 88200, 96000, and 192000 Hz. You can also type any custom integer sample rate in the Custom field.

What is PPQ / ticks per beat?

PPQ (Pulses Per Quarter-note) is the resolution of a DAW's internal clock. Common values are 480, 960, and 9600. One beat equals one PPQ's worth of ticks; fractional ticks let you place events between beats with high precision.

Why do the frame-rate columns show slightly different sample numbers?

Frame rates like 29.97 fps are non-integer (they equal 30000/1001 fps), so the sample-to-frame mapping has a small but accumulating rounding error. The table shows the nearest sample boundary for each frame rate purely as a reference; the primary sample number is exact.

How accurate is the bar/beat conversion?

The conversion assumes a constant tempo with no tempo automation. If your DAW project has multiple tempo changes you will need to account for each segment separately. For constant-tempo projects the result is exact to the nearest sample.

Can I use this for MIDI tick calculations?

Yes. In bar/beat mode, entering ticks directly (with beats = 0 and bars = 0) gives you the sample offset for any raw MIDI tick position relative to the timeline start.

Summary

Enter a timecode (HH:MM:SS.ms) or bar/beat position plus a sample rate to get the exact sample number for a DAW cut point.

How it works

Select whether you want to convert from a timecode or a bar/beat position.
Enter the timecode (hours, minutes, seconds, milliseconds) or the bar, beat, and tick values.
Choose the sample rate — or enter a custom value in Hz.
For bar/beat mode, also enter the BPM and the number of ticks per beat (PPQ).
Click Calculate to see the exact sample number, plus the rounded frame position at common frame rates.

Use cases
