Seed Audio 2.0: The Next Generation of AI Audio Scene Generation

Overview

Seed Audio 2.0 is an advanced AI tool designed to create complete audio scenes from a single text prompt. Unlike traditional text-to-speech tools that only generate isolated lines of dialogue, Seed Audio 2.0 acts as a scene renderer. It can produce dialogue, music, background ambience, and sound effects all at once. The platform supports complex workflows including text-to-audio, audio-to-audio, video-to-audio, and even text-audio-video-to-audio. While the full capabilities are currently in preview, users can rehearse prompts using the existing Seed Audio 1.0 studio. Early-bird pricing is available for those who wish to reserve capacity for the new model.

Benefits

Seed Audio 2.0 offers several key advantages over previous models. It significantly expands the scope of what can be generated in a single pass. Users can now create scenes up to six minutes long, compared to about two minutes in the older version. The tool allows up to six reference audio clips to ensure distinct character voices remain consistent across longer stories. It also supports 30 languages, making multilingual localization easier without the need for manual re-recording.

A defining feature is its ability to output independent stems. Instead of a single mixed audio file, users can separate dialogue, music, ambience, and effects. This allows editors and sound designers to manipulate individual layers on a timeline, adjust timing, or swap elements without affecting the entire mix. The model also supports video context, meaning it can analyze video input to understand action and pacing. This ensures the generated audio aligns precisely with visual cues rather than just laying narration over a silent timeline. Users can guide the generation using text prompts, reference audio for voice cloning, and reference images to set the mood and location.

Use Cases

Seed Audio 2.0 is targeted at professional production workflows rather than simple mood boards. Ideal applications include creating multi-scene shorts for films and comic dramas where voices and beds must remain consistent across cuts. It is also great for advertising and brand films, allowing teams to generate voiceovers, product sound effects, and music lifts in one pass for easy localization. Game developers can use it to produce boss lines, forest loops, and UI hits that can be split for game mixers.

The tool is perfect for dubbing content into 30 languages with video context awareness. It can also generate longer narrative audio, such as podcast cold opens or comic-drama acts that exceed the limits of previous models. To get the best results, users should structure their brief with a specific formula including the scene, speaker, emotion, language, ambience, music, sound effects, and timing. The workflow involves writing the scene, parking reference audio clips, setting output limits, and then listening and refining the result as an editor would.

Pricing

Pricing structures vary by region and platform version, but the model generally follows a credit-based system. Usage typically costs five credits per minute of generated audio. Purchases are often one-time credits valid for 365 days instead of recurring subscriptions. There are different credit packs available. A starter pack includes about 120 credits for 24 minutes. A creator pack offers around 500 credits for 100 minutes. A studio pack provides approximately 2,000 credits for 400 minutes. New accounts often receive a small number of free credits, such as 10, for testing purposes.
