Room Echo Reduction
Reduce lingering room reverberation in a voice and compare the effect of different strengths.
Before you start
Open the intended collection and layout. Rehearse changes before using them during a live production.
Where to find it
Input Filters in Audio Mixer or the source’s filter action.
Use it
- Open the microphone/input’s Filters and add Room Echo Reduction.
- Adjust Room echo reduction (%) gradually while speaking; compare the voice at different strengths.
- Record a short sample with speech and, if relevant, speaker playback.
- Listen to the completed sample and compare with the filter disabled.
Choose the right cleanup
Speaker Echo Cancellation reduces speaker playback picked up by the microphone. Room Echo Reduction reduces lingering room reverberation. The combined filter addresses both. These are different from muting an input, noise suppression or fixing duplicate routes.
Room echo reduction ranges from 0 to 100%. Higher strength can change the voice, so use the lowest effective setting.
These controls cannot promise removal of every echo. First avoid sending monitored playback back into its own capture, reduce speaker volume or use headphones, then check the filter with a sample.
