Reduce reverb in a recording: improve roomy speech
Distinguish room decay from repeated echoes, then set up and review De-reverb.
De-reverb
Reduce late room reflections in reverberant speech.
When should you choose this tool?
Speech recorded in an empty room or far from the microphone can leave a tail after each syllable. That tail may overlap the next word. De-reverb targets room decay; distinct repeated echoes are a different problem.
How it changes audio
It estimates late decay per frequency from previous signal energy, while seeking to preserve direct sound and early reflections. It does not automatically measure the room’s acoustic reverberation time.
What do the parameters control?
- Decay time (estimate)
- 100–2000 ms. Sets assumed decay in the processing model. Tune against audible tails after word endings rather than guessing from room size.
- Early sound protection
- 10–100 ms. Shapes preservation of onsets and early sound. Listen for intact syllable attacks.
- Maximum reduction
- 0–24 dB. Limits attenuation of estimated late decay. High settings may also affect sustained speech.
- Processing blend
- 0–100%. Blends original and treated audio. A gentler blend can preserve a more natural sense of space.
Try a short passage
- Find a short sentence followed by a pause so its tail can be heard separately.
- Start Preview with gentle reduction and tune decay time to the audible room tail. Residual should mostly contain decay.
- Check continuous speech and sustained vowels too. Reduce attenuation or blend if the voice becomes choppy.
What to listen for
Distracting tails should shorten while speech onsets remain intelligible. Drier sound alone does not establish better intelligibility.
Limits of the method
It does not detect discrete repetitions or restore words masked by reflections. Long musical notes may also be treated as decay.
Preview covers a short passage. After applying, review the full treated section; you can undo the step from history.
