AI Sound Effect Generator for Games

Describe the sound you need, choose a length from 0.5 to 5 seconds and up to three variations, and the AI sound effect generator returns MP3 files you can play and download. It runs on your Ziva account: each generation uses your Ziva plan's AI usage.

Step 1 of 2: Describe the sound

How to use it

  1. Type a description of the sound, or press one of the examples, and press Next.
  2. Set the Length slider and choose 1, 2 or 3 Variations. Sign in to Ziva if you have not yet.
  3. Press Generate sound and wait for the variations to finish.
  4. Play each variation and press Download MP3 on the ones you want to keep.
  5. Press Generate again for a new set, or Change inputs to edit the description.

How to describe a game sound effect

Name the objects, the material and the action: "sword hitting a wooden shield" works better than "combat sound". Add the space when it matters, such as "footsteps on snow in a quiet forest" or "door slam echoing in a stone hall".

Ask for one event per sound. A single impact, a single footstep or a single spell cast is easier to place in a game than a sequence, and you can layer separate sounds in the engine later.

Keep the length close to the real event. Hits, clicks and pickups usually sound right under a second; doors, portals and machines can use two to five seconds. Generate two or three variations and pick the best, or keep several to rotate between so repeated actions don't sound identical.

Using MP3 sound effects in Godot

Godot imports MP3 alongside WAV and Ogg Vorbis. Its documentation notes that MP3 needs less CPU to play back than Ogg Vorbis, which helps on mobile and web projects. For very short sounds that play constantly, such as footsteps or gunfire, WAV is the cheapest to play, so you can convert the most frequent sounds to WAV if you need to.

Copy the MP3 into your project, add an AudioStreamPlayer (or AudioStreamPlayer2D or AudioStreamPlayer3D for positional sound) and set its stream to the file. To rotate between variations, add them to an AudioStreamRandomizer, which picks a random one each time and can add a small random pitch change.

Ziva can also generate sound effects directly inside the Godot editor, so you can ask for a sound and have it added to your project and hooked to the right event without leaving the engine.

Frequently asked questions

Is the AI sound effect generator free?
It needs a Ziva account, and each generation uses your Ziva plan's AI usage. More variations and longer sounds use more. The retro sound effect generator is fully free and runs in your browser.
How long can a generated sound effect be?
Between 0.5 and 5 seconds. For longer ambience or music, generate shorter pieces or use a dedicated music tool.
What format are the sound effects?
MP3 files. Godot, Unity and Unreal Engine all import MP3, so you can drop them straight into your project.
Why do I get a different sound each time?
The AI generates new audio every time, even from the same description. That is why you can ask for up to three variations at once and keep the ones you like.
What should I write to get a good game sound effect?
Describe one event with its objects and material, such as a sword hitting a wooden shield or footsteps on snow. Vague words like epic or cool give unpredictable results.
