How do I align two microphones that are out of phase?

Measure the distance between the mics, enter it with the correct unit and room temperature, and the tool gives you the exact delay and sample offset to apply in your DAW.

What frequency will cancel out from my mic spacing?

The half-wavelength cancellation field shows the frequency where phase cancellation is worst for your spacing. It is a quick check to see whether the comb filtering lands somewhere you will actually hear.

Why does room temperature affect mic phase alignment?

Sound travels faster in warmer air. The tool adjusts the speed of sound based on your temperature input, which changes the delay calculation by a small but measurable amount.

How the math works

Time offset is distance divided by speed of sound. Once you have the delay in seconds, multiply by sample rate to get the sample offset. Half-wavelength cancellation shows up at speed divided by twice the spacing distance.

When you would use it

Align a close snare mic against an overhead pair.
Check the timing offset between inside and outside kick mics.
Estimate the frequency most likely to cancel when two mics are spaced awkwardly.

FAQ

Why allow room temperature?

Because the speed of sound changes slightly with temperature.

Does sample alignment always sound better?

No. It changes tone and impact, so treat it as an option rather than a default fix.

Why show the cancellation frequency?

It tells you roughly where the biggest comb-filter problem may show up.
