Apply reverberation effect to your audiotracks to add echoes (similar to open-air environments)

from the official website.

Reverberation, also known as reverb, is a type of audio effect commonly used in video editing, music production, and post-production. It simulates the reflections of sound waves bouncing off surfaces in an acoustic space or environment, creating an echo or a sense of depth and spaciousness to an audio track. Reverb can be added to dialogue or voiceover recordings to make them sound more natural and realistic. For instance, if you're producing a film set in a large cathedral or an open-air marketplace, adding appropriate reverb to the dialogues will help create a more immersive experience for the audience. It can also be used in music videos and commercials to enhance the audio quality of musical performances or sound effects. For example, adding reverb to drums or vocals can make them sound more dynamic. Similarly, adding a long reverb tail to an explosion or other sound effects can make them seem more powerful and realistic.

Navigate to the left sidebar and click on More tools. Go to the Audio section, locate the Reverberation option and select it.

Select your audio clip in the Timeline. Modify the parameters:
- Duration (duration of the reverb effect)
- Delay (amount of time before the reverb begins)
- Dry/Wet balance (balance between the original sound and the reverb-altered sound)
- Frequency (threshold -- to ignore high frequencies beyond the defined value)
Once you've fine-tuned these settings, the changes will be automatically applied to your audio clip.
