How do I add reverb to a song online?
The answer
Open a reverb tool that runs in the browser, such as the SongUp AI Add Reverb tool below, and choose the audio file. Pick a space (Hall is a good start for music, Vocal Plate for singing, Small Room for speech), set Mix to about 25–35% and leave the decay the preset gives you, press Preview to hear it, then Add reverb and download the MP3 or WAV. The file never leaves your device.

Tips
- Less is more: 20–30% mix keeps the words clear on a vocal.
- For the slowed + reverb sound, use the Slowed + Reverb Maker instead; it slows the song too.
Questions
Is it free?
Yes. It is completely free, with a free account: no limit and no watermark. It runs in your browser, so your audio stays on your device.
Is my file uploaded?
No. The reverb is calculated on your device with the browser’s audio engine.
Can I add reverb to vocals only?
If you have the vocal on its own, yes. For a finished song, run it through the Acapella Extractor first, add reverb to the vocal and mix it back with the instrumental.
