Why Use Submind's Sound Effects Tool?
Twenty-five effects applied to your own recording, without an upload and without an account.Your Audio, Not a Sample Library
These are processors, not downloads. The recording you pick comes out sounding like a stadium, a phone call or an old radio, and the original stays on your disk.
Hear the Effect Before You Render
The preview and the file run the same audio graph. Change the effect while it loops and you hear the room, the echo or the drive change immediately.
Private and On-Device
The audio is decoded, processed and encoded inside the tab. Nothing is uploaded, nothing is stored, and no account is involved.
MP3 or WAV, No Watermark
Download MP3 at 192 or 320 kbps, or a 16-bit WAV for editing. There is no watermark, no render minute and no sign-up step.
How to Add a Sound Effect to Audio in 3 Steps
One engine, twenty-five presets, all inside your browser.Pick the Recording
Choose an MP3, WAV, M4A, FLAC or OGG file. The browser decodes it on your device, so the audio never leaves the tab.
Choose an Effect and Set the Amount
Start with a room such as Stadium, a device such as Telephone, or an ambience bed such as Rain. The preview loops while you sweep the amount slider.
Render and Download
The effect renders in seconds. Pick MP3 192, MP3 320 or WAV, and the filename records which effect you used.
Where These Effects Get Used
One engine, three kinds of work.Podcasts and video edits
Put a phone call through Telephone, drop a flashback into Vinyl, or give a scene an empty-room tail with Small Room.
Games, streams and roleplay
Robot, Megaphone and Walkie-talkie give a character a voice that is recognisably not the narrator. No plugins, no install.
Music and sound beds
Widen a dry take with Arena or Church, then set the mood under it with Rain, Cafe murmur or Applause at a low level.

Sound Effects Questions
What the tool does, and what it deliberately does not do.No. It applies an effect to audio you already have. If you need a whoosh or a door slam as a file, a sample library is the right tool. If you need your own recording to sound like a stadium, a phone call or an old radio, this is the right tool.
