Matthew Weiss has a great video on this: Conventional, minimum-phase EQ alters the phase of sounds. Focal's spirit : Listen Beyond 'Made in France' know-how Focal's story Vervent Audio Group, © 2017-2020 Focal-JMlab. Inverse the 2 frontal loudspeakers phase (right and left) by inversing the polarity of their respective cables: Proceed to the automatic calibration measure. Listen to the two together. When you flip the polarity on a track, you’re actually just reversing the direction of its waveform. This issue is well known by loudspeaker and home cinema amplifier manufacturers. Flip the polarity in and out, and choose what that sounds best. If two tracks are only slightly out of phase, for example, a polarity flip alone will leave you stuck choosing between the lesser of two evils. Most mixing decisions are tradeoffs, and the best mixers know when to leave tracks alone. When using them, check your mix in mono to make sure tracks don’t disappear. The best time to fix phase cancellation is at the beginning of a mix. I don’t recommend using these plugins across your whole mix. This doesn’t mean you shouldn’t focus on it. Normally, this isn’t a problem. All of our loudspeakers are designed in order to get the best performances for hi-fi as well as home cinema use. The effect can sound great in stereo, but horrible when summed to mono (or even when your mix is played on speakers that are close together). You can also opt to use a linear-phase EQ instead. Solo the next drum sample as well. And avoid the solo button…please! When it comes to phase, a blanket fix-all approach isn’t always appropriate. for high-fidelity loudspeakers, Declaration of conformity for the European Union. By proceeding in this manner, the automatic calibration will be more accurate. Many mixers forget to check for phase cancellation between layered drum samples. The worst-case scenario is a total cancellation of the audio if the two elements are 180-degrees out of phase (where the peaks of the waveforms are pointing in opposite directions at a given point in time) during mono playback. There’s no use adding mountains of EQ or compression if a simple polarity flip can give you what you’re looking for. However, linear-phase EQs aren’t a catch-all, as using them can cause other problems (like pre-ringing). While time alignment can yield a tighter, punchier sound, it can also flatten and destroy this depth. Don’t make mixing decisions in isolation. For this reason, it’s worth exploring other options. The left and right speakers are often in different rooms entirely. It mainly comes from the fact that the home cinema amplifier doesn’t know how the loudspeaker crossover has been designed and where the loudspeakers are placed in the listening room. This approach works well when you have two mics that were placed at unequal distances away from an instrument (e.g., inside and outside kick drum mics). Step back several feet from any set of speakers, and you’re effectively listening in mono. It destroys impact and obliterates low end. And sure, on headphones, stereo width matters. For an easier solution, try Sound Radix’ Auto-Align. Phase cancellation is the silent killer of great mixes. For this reason, I’m not a big fan of stereo imaging plugins. For a correct measure during the calibration, you only need to inverse temporarily the loudspeakers polarity (left and right) during the measurement. All rights reserved. Always check for bass cuts fixed by the automatic calibration and do not hesitate to retouch the subwoofer and centre speaker volumes as they are rarely perfect. There is a tradeoff, however. By adjusting the blend between the two mics, you can create a unique sound that cuts through a busy mix. Not all phase problems should be fixed. To fix it, a repair shop would need to swap the speaker wires over on just one speaker (assuming it is just a phase … Some automatic calibration software can mistakenly consider the main loudspeakers as out of phase. Some actually enhance your mix. A common cause of poor performance in an audio system is also one of the easiest to fix – if you know what to look for. Make a decision and move on.). Enter Focal's universe. Listen for depth when making time-alignment decisions. With plugins like these, it’s tempting to go trigger happy and optimize everything. Solo it. Phase cancellation can also create depth. How To Fix Out of Phase Audio In the Mix Obsessing over stereo width is a waste of time. Pay attention to how your decisions affect groups of tracks, as well as the mix as a whole.

First, realize there’s a difference between polarity and phase. Implement them to add punch and weight to your mixes. But most of all, it’s seriously frustrating. But EQing correlated sounds (like a snare drum that’s part of a multi-mic’d drum kit) can cause unexpected problems. Since they don’t create phase shifts, they aren’t subject to phase-related problems. Check for phase cancellation during mix prep, before you add any processing. Always A/B your decisions and listen closely for downsides—fixing one problem can often create others. The changes are the result of approximately 4 milliseconds of delay on a layered kick sample. Just don’t get too caught up here. Hi, If your system is out of phase, both speakers should sound different, not just one, although if when the phase test swaps, so does the loudest speaker, it could potentially be a phasing problem. Extended Warranty Listen to the punch and low end of the combined sound. If you’re going to use them, be careful. While certain genres may benefit from a punchy, one-dimensional sound, others may warrant a more natural approach. This plugin will automatically optimize timing relationships between different tracks. When it comes to phase, a blanket fix-all approach isn’t always appropriate. It mainly comes from the fact that the home cinema amplifier doesn’t know how the loudspeaker crossover has been designed and where the loudspeakers are placed in the listening room. Remember—phase cancellation can crop up in any mix, regardless of genre. Pick a “master” drum sample that you’ll compare the others to. Its 'Made in France' know-how has been recognised for more than 40 years. For starters, zoom in on the waveforms in your DAW and compare the peaks and valleys of different tracks.
