More about Seed Audio 1.0

Seed Audio 1.0 — AI Sound Scenes from a Description

Seed Audio 1.0 builds a complete sound scene from a single text description: voice, ambience, background music, and effects arrive as one track. It is the fastest way to get an atmosphere for a video or a game — right in the browser on NetRoom.

What it does

Describe the scene — 'a night forest after rain, distant thunder, a narrator speaking by the fire' — and get finished audio with every layer in place. No hunting for stock ambience, effects, and narration to mix later.

Who it is for

Video creators get sound design without stock libraries. Game developers generate location ambiences from a brief. Podcasters make intros and stingers. Marketers get an audio bed for an ad in one generation.

How to use it

1. Sign up on NetRoom and top up your balance. 2. Open the Sound section and pick Seed Audio 1.0. 3. Describe what sounds, where, and in what mood. 4. Download the result as MP3, WAV, FLAC, or OGG.

Pricing
