AI Game Audio — Sound Effects, Soundscapes and NPC Lines

Placeholder audio kills immersion and licensed packs never quite fit. Describe the exact sound your scene needs — a rusty gate, a haunted forest, a shopkeeper greeting — and generate it.

AI Game Audio — Sound Effects, Soundscapes and NPC Lines

Game audio splits into three buckets, and Seedaudio covers each. Discrete SFX (UI clicks, impacts, spells) and ambient loops (dungeon drips, market crowds, storm systems) come from Seed Audio 1.0 prompts — describe the material, the space, and the intensity. NPC voice lines come from Seed Speech 2.0: 40 voices across 10 languages, with voice_instruction to act each line ("gruff blacksmith, suspicious of strangers").

Ambience generations run up to two minutes and Extend continues them seamlessly for long loops. Everything downloads royalty-cleared for commercial games, and localizing NPC barks into ten languages is a re-generate, not a re-cast.

How it works

1. Describe

Name the sound with physical detail: "heavy iron gate creaking open in a stone corridor, echoing" beats "door sound". For NPC lines, write the dialogue plus an acting instruction.

2. Generate

Generate and audit in seconds. Batch variations by tweaking one adjective — wood vs iron, distant vs close, calm vs violent — to build a coherent SFX family.

3. Extend & download

Extend ambient beds into long seamless loops, download MP3/Opus, and drop them into Unity, Unreal or FMOD. Commercial license included.

Thunderstorm ambience (generated for a storm system)

Rolling thunderstorm ambience: heavy rain on foliage, distant rumbling thunder, occasional close cracks, loopable.
