Why Noise Gates Chop Off Laughs & Quiet Words

Beginners often slap heavy single-track noise gates onto each mic. The moment both hosts laugh together or speak softly, gates chatter open and closed—letting room echo burst right back in. Comparing both mics together solves spill smoothly without choppy pumping.

Works with Two USB Mics, Lavaliers, or Smartphones

Whether you recorded on two Blue Yetis, two wireless clip-on mics sitting close on a sofa, or two iPhones on a coffee table, locking both tracks first eliminates slapback delay.

Frequently Asked Questions

How do I get rid of echo when two microphones record in one room?

Upload both microphone tracks into SyncCast above. By locking exact timing drift between the two recorders and attenuating whichever mic is farther from the active voice, the hollow double-voice echo disappears.

Can I still edit each host's EQ separately afterward?

Yes! Click Download Mic 1 WAV and Download Mic 2 WAV to get separate time-locked, bleed-cleaned stems for Audacity, Premiere, Reaper, or Descript.
