Common questions
If your video needs a long, continuous track (over 3 minutes), Sonauto is better because it can generate up to 4.5 minutes. For shorter clips, Stable Audio is better because its output quality is more consistent and easier to produce.
No. Neither Sonauto nor Stable Audio has a mobile app. You need a computer with a web browser and an internet connection to use them.
Stable Audio is easier. Its interface is simpler – you just type a prompt, adjust a few sliders, and download. Sonauto has more options and a preview model that can be confusing.
Both have unclear pricing. Sonauto's pricing is not published at all. Stable Audio also doesn't show clear pricing, but it's likely a freemium model. You should check their websites for the latest info before committing.
Stable Audio is better for sound effects because it explicitly supports sound effect generation and produces high-quality, short clips. Sonauto is more focused on full music tracks.
Stable Audio wins for most people thanks to its ease of use and consistent quality, while Sonauto is the pick if you need very long tracks or developer features.
