Pro audio topics on phase issues. How to avoid, fix and repair phase related problem when recording, mixing and mastering.

M/S and mixing ribbons and condensers - possible phase issues?

I posted recently about a job coming up where I was going to use a condenser mid mic, and a ribbon side mic, and useful piece of information emerged. There was some evidence that as ribbons use a different operational mode there would be a 45 degree phase shift, and this could wreck M/S recordings which use combining channels to produce the stereo channel that can then be adjusted in width after the recording - a useful technique.

Polarity vs. Phase - Why do I need to know this? (video)

Polarity and Phase are 2 things that anyone who does music production needs to master.
Even if you only have a home studio, as soon as you start to use more than one microphone to record or if you are doing a lot of overdubs with the same instrument and mic.

Knowing what phase and polarity is will help to avoid mistakes that can diminish the sound quality of your music.

Also many engineer use the term phase to designate polarity. This mistake can lead to misunderstanding when discussing audio with other engineers.

Let me know what you think ! ;)

Eq116 vs. ozone 9 FIR EQ vs. mAAT EQ Orange for Linear Phase Quality

I love the eq116 Linear phase mode filters but I did some research I was told that "Maat EQ Due to the double IIR Filter the lowcut becomes a Linkwitz-Riley Filter. For me and many others it’s the king of the surgical filters and it can really work miracles." really have this degree difference between eq116 and maat eq orange or Ozone 9 digital (surgicel FIR eq) ? Ozone 9 also has very clean FIR filters and the CPU uses it very well and is affordable, or eq 116 linear phase eq is very clean transparent and does not tire the CPU too much.

Phase Issues with this recording? Fixable?


I lurked on this site a lot some years ago, and may never have posted. Posting now, though, made me think of the joke about the parents who were worried because their 5 year old boy never spoke. Then one day at breakfast, he said, "The toast is burned." The parents were thrilled, but then asked why he'd not spoken all this time. He said, "Up until now, everything's been OK."

Phaser/Flange everywhere.

Folks, no matter what app I use to record myself singing and playing guitar, the guitar always projects a phaser/flange type sound. I deactivate those effects in the given apps but it still happens. I am running Win 10. Any input is much appreciated. I know this question and my level of recording is not up to the standards of the forum overall but still would appreciate hearing from you. Thanks

EQ116 Linear Phase - subtle 'PLOC' noise

Hi there.

This problem has haunted me every time I use the 'Linear Phase' mode on the EQ116: a subtle but audible 'PLOC' is added exactly in the beginning of some tracks.

When I change to 'Oversampling' or 'Normal' modes, this subtle noise disappears.

I know that, according to the manual, 'Linear Phase' requires high processing power, but my question is: is there any hint that I can continue using 'Linear Phase' mode without the mentioned noise?

These are my settings:

Drum Overhead Mics Time/Phase Alignment

So for years now, at least since DAWs have given us the ability to move audio files around by infinitesimal amounts within a time line, I've both read and talked to other engineers about time aligning the overhead drum mics to the Snare and Kick...
I know there's also software available that can apparently time align those mics/tracks, although I've never used it.

Avoiding phase when doubling strings


I am recording a string section which consists of 6 violins and 2 cellos. We will be doubling ( by re-recording a second take ) the section and are concerned about potential phasing issues.
Does anyone have any advice as to how to avoid any phasing between the doubled parts at the recording phase.

Is it a valid concern ? Or will the fact that the parts are being played again avoid any noticeable phasing ?
