Phase Cancellation is an auditory phenomenon that occurs when two waves cancel each other out, resulting in loss of sound quality. This effect can be greatly detrimental to the effectiveness of performances and clarity of communication on a stage. Phase cancellation happens when the peaks of one wave align to cancel out the troughs of another wave. Using 2 mics at a 90 degree angle, adding paneling to the venue, or implementing a delay can help prevent phase cancellation and loss of sounds.
Key Takeaways:
- Phase cancellation is when two sound waves interfere with each other and reduce volume at specific frequencies.
- The most common cause of phase cancellation is using the same audio source for recording and/or poor microphone placement.
- You can prevent phase cancellation by having proper microphone techniques as well as using acoustic panels in your recording studio.
“The result is a sharper stereo image full of the frequencies you want while suffering no spikes in the ones you don’t want.”
