Udio: The Producer's Choice
Udio rewards those who know what they want. Its genre tagging system is more granular than Suno — you can specify instruments, production era, regional sub-genres and mood in a single prompt. The output has a slightly more "crafted" quality, with better stereo separation and less AI-typical compression artefacts in the high frequencies.
