Two or more mics in one room. Podcast. Interview. Panel. Each mic hears every voice. That leakage is mic bleed, also called crosstalk.
A noise gate is the usual first fix. On multi-mic dialogue it often fails. A gain-sharing automixer solves a different problem: it compares the tracks.
Mic bleed is the other speaker on your track. Same room, separate lavs or dynamics, close seats. The inactive mic still picks up the active voice, room tone, and chair noise.
Bleed is not echo from headphones. It is not broadband noise. It is speech on the wrong track.
Start on the floor. Distance between mics. Angle. Polar pattern. That cuts bleed before you open the DAW.
In the edit you still have leftovers. Common tools: noise gate, expander, strip silence, sidechain ducking, manual clips. Each looks at one track at a time. None of them knows which mic is the intended speaker.
A gate opens and closes from that track's level only.
Bleed is often as loud as the start or end of a word. The gate opens late, cuts consonants, or chatters. During overlap both speakers talk, both mics stay open, and the gate does nothing useful.
That is why "noise gate not working on mic bleed" is a common search. The tool is wrong for the job.
Two mics, same table. When A talks, B's track still has A. When both talk, both tracks stay open.
Chopping by hand works on a short take. On a two-hour interview it does not. Sidechain ducking ducks the wrong signal when the key is bleed.
You need a process that compares levels across mics.
A gain-sharing automixer looks at all mic tracks together. It compares levels across mics. The active mic stays open. Quieter mics attenuate. During overlap, more than one can stay open. When one speaker stops, that mic goes down.
It is not a spectral de-bleed. It does not invent isolation from one file. Instances run together and share level data in real time.
Placement still matters. Automix cleans residual bleed. It does not replace distance.
Where to start on the floor: Mic placement for a two-person podcast.
Same mess here — two or three lavs that close, placement only goes so far. That's why I developed AntiBleed, a plugin in VST3 and AU formats.
One instance per mic track. Instances find each other and share levels. Inactive attenuates. Active stays open. Zero latency. Up to 16 mics.
macOS 12+ (Intel and Apple Silicon) as VST3 and AU. Windows 10+ (64-bit) as VST3. Logic, Reaper, Cubase, Nuendo, Studio One, Ableton Live, Fairlight, Audition and other hosts.
$69 one-time. Lifetime license. Free updates. 14-day full trial, no signup.
