Size, decay and mix do different jobs
Size is how long the tail lasts, which your brain reads as how large the space is. Decay is how quickly it fades within that time — a high value dies away fast and sounds absorbent, like a carpeted room; a low value hangs on and sounds hard and stony.
Wet mix is how much of the reverb you hear against the original. This is the one people overdo. Above about 50% the source starts to sound distant and washed out; most professional mixes sit between 15% and 35%.
The tail is added, not cut
The output is deliberately longer than the input, by exactly the length of the reverb tail. Almost every quick browser reverb gets this wrong: it renders into a buffer the same length as the source, and the decay is chopped off the moment the audio ends, which sounds abrupt and wrong.
The preview renders the first eight seconds so you can judge the setting without waiting for a whole track.
Reverse reverb
Ticking reverse flips the impulse so the sound swells into each note rather than decaying away from it. It is a deliberate studio effect with no natural equivalent — used ahead of a vocal entry or a drum hit to build anticipation. Keep the wet mix low or it swamps everything.
Frequently asked questions
Can I remove reverb instead?
Not with this, and not easily with anything. Reverb mixes the original with countless delayed copies of itself, and unpicking that requires machine learning rather than a filter. Record in a drier space if you can — adding reverb is easy, removing it is not.
Is my audio uploaded?
No. The convolution runs in your browser — the file never leaves your device.
