There's no need for licensing because the tool will automatically create sound effects based on video uploads, game parameters or detailed text prompts.
Another good option is Audiobox, which lets you synthesize voices and sound effects with natural language text prompts. The service is geared for creative projects, with tools like audio editing and the ability to create sound effects from text prompts. It can sometimes spit out bogus results, but Audiobox offers a broad range of audio generation abilities.
