How to use this workflow
Establish the reference
Keep an unchanged source and identify the passage or signal relationship described below.
Compare the combined signal
Keep the two source tracks separate in an external editor. Listen to each alone, then combine them at a documented gain. Compare a polarity inversion with a small alignment correction, changing one operation at a time. A louder result is not proof of correct alignment: check attacks, low notes and mono playback. Reflections may prevent a single delay from aligning the whole recording.
Verify the saved result
Reopen the downloaded file and compare the relevant event with the source. Keep the source and the settings note for a later revision.
Calculate a delay at two frequencies
For an illustrative 1 millisecond delay, phase difference is 360 × frequency × 0.001 degrees. At 500 Hz this is 180 degrees; at 1000 Hz it is 360 degrees, equivalent to one full cycle. A polarity flip instead multiplies both tones by −1. It cannot align two microphone arrivals across all frequencies. These are sinusoidal calculations, not measurements of a room.
Swipe or scroll sideways to read all columns.
| Item | Value or action | Meaning |
|---|---|---|
| 500 Hz, 1 ms | 180 degrees | Half a cycle |
| 1000 Hz, 1 ms | 360 degrees | One whole cycle |
| Polarity inversion | Multiply samples by −1 | No time displacement |
Apply the result within the tool’s limits
PitchChanger does not expose a polarity-inversion or multitrack alignment control. Its stereo effects create spatial changes; they are not a repair for two misaligned microphones. Use an editor that can preserve separate tracks, then export a reference for comparison.
Common questions
Are the example numbers device test results?
No. Numerical examples and worksheets on this page are authored explanations. They do not measure your recording, browser latency or listening accuracy.
