Reverb, explained.
Reverb is the lingering sound you hear after a note stops, as sound reflects around a space. Early reflections help suggest nearby surfaces; a dense decay adds the feeling of a room or hall. Sonic blends a generated reflection pattern with your recording rather than simulating a particular real building.
Every parameter, explained
Room size
0% to 100% · Default 95%Room size controls the length of the reflection tail. The range corresponds to approximately 0.4–5.9 seconds of generated impulse response. A larger value makes sustained notes overlap for longer; it does not change the loudness of your original track.
Reverb mix
0% to 100% · Default 51%Reverb mix blends dry audio with the reflections. 0% is dry, 100% is only the reverberated signal. The blend uses an equal-power curve, so 50% is not a simple half-volume split.
A good place to start
Start around 35% room size and 25% mix for a vocal that needs a little space. For an atmospheric instrumental, try 75% room size and 45% mix. The default 95% / 51% setting is intentionally spacious.
What to listen for
Too much reverb can blur consonants, drum hits and bass notes. Listen to the pauses between phrases as well as the loud sections. The download includes an added tail when the mix is above zero; leave that ending intact if you want the decay to finish naturally.
Does it change speed or pitch?
No. Reverb keeps playback speed and pitch intact. Its added decay can make the exported file longer.
