Yes, you should always check the polarity of a sub-kick, but you only leave it flipped if it improves the sound. Because a sub-kick (whether a sub-microphone or a sine wave trigger) occupies the same frequency range as the low-end of your main kick, their waveforms must move in the same direction at the same time. If they are 180 degrees out of phase, the peaks of one will fill the troughs of the other, causing destructive interference (phase cancellation) that results in a weak, thin kick sound.
- 1.Duplicate your kick track or record the sub-kick alongside the main kick.
- 2.Listen to both tracks summed to mono at a moderate volume.
- 3.Engage the Polarity Flip (often labeled as Ø or Phase) on only the sub-kick channel.
- 4.Compare the low-frequency weight: The setting that sounds 'fuller' and has more 'thump' in the sub-bass region is the correct one.
- 5.Check for 'hollowness': If the kick sounds thin or like it's clicking without body when both are on, they are likely canceling each other out.
- ×Overlapping frequencies: If both kicks have too much energy at 60Hz, swapping polarity might fix the phase, but you may still have a 'muddy' mix. Use a high-pass filter on the main kick or a low-pass filter on the sub-kick.
- ×Time alignment: Polarity is just a flip; phase is a timing issue. If the sub-kick is delayed by a few milliseconds, flipping polarity may not be enough. You might need to physically nudge the sub-kick region to align the transients.
- ×Monitoring: Do not check polarity alignment on small laptop speakers or earbuds; you need a subwoofer or high-quality studio headphones to hear the low-end cancellation properly.
Zoom in deep on your waveforms. Don't just look for 'up' vs 'down'; look for the zero-crossing points. If you align the start of the waveforms perfectly, you might not even need to flip the polarity.
