What is the difference between echo and reverb in audio?

Echo is a distinct, delayed repetition of a sound that occurs when reflections arrive more than 50 milliseconds after the original signal. You can hear the original sound and its "copy" separately. Reverb is a dense collection of overlapping reflections that arrive under 50 milliseconds, creating a sense of space or "thickness" around the sound rather than a separate repeat. In Premiere Pro, the DeReverb effect handles both, but echo typically requires higher reduction settings.

Can you completely remove echo from a recording in Premiere Pro?

In most cases, you can significantly reduce echo, but completely removing heavy echo without any quality loss is extremely difficult. Premiere Pro's DeReverb and Essential Sound Panel work well for light to moderate echo. For severe cases, you may need third-party tools like iZotope RX. The key is to reduce echo enough that dialogue is clearly intelligible without over-processing the audio.

Why does my audio sound hollow after applying noise reduction?

This is one of the most common causes of hollow-sounding dialogue. Noise reduction works by removing frequencies it identifies as noise, and aggressive settings can accidentally strip away frequencies that are part of the voice, particularly in the 1-2 kHz "presence" range. The fix: reduce the intensity of your noise reduction and use Parametric EQ to gently boost the 1-2 kHz range to restore vocal body.

What is the best DeReverb setting in Premiere Pro for dialogue?

Start with the Default preset and adjust the Amount slider between 40-60% for most dialogue recordings. Light recordings need only 20-30%, while heavily echoed audio might require 70-80% with the Heavy preset. Always enable Auto Gain to compensate for volume loss. The most important tip: preview your changes constantly and stop increasing the amount as soon as the echo becomes unnoticeable; going further will degrade voice quality.

How do I fix echo in a video recorded in a large room?

Large room recordings typically need a combination approach. Start with the DeReverb effect at 50-70% (Heavy preset if needed), then apply Parametric EQ to cut the low-frequency room resonance (typically below 200 Hz for large spaces). If the voice still sounds thin, add a gentle EQ boost in the 1-2kHz range. Enable Auto Gain on DeReverb, and consider using Enhance Speech AI as a final polish. For extremely problematic recordings, third-party tools like iZotope RX offer the most surgical control.
