About
CraftMusic AI is an AI-powered music and lyrics generation platform that helps creators move from a prompt, lyric idea, or project brief to original songs and instrumentals. The platform offers two main tools: an AI Music Generator for creating songs and instrumentals for videos, podcasts, games, ads, and social media edits, and an AI Lyrics Generator for turning themes, moods, titles, or story ideas into structured lyrics with hooks, verses, choruses, and rap lines. Key features include: text-to-music generation, instrumental-only mode, vocal direction control, genre and style tags (50+ styles including Hip Hop, Jazz, Pop, EDM, Folk, Rock, Classical), draft comparison and download workflow, AI vocal remover, AI stem splitter, AI mastering, BPM tapper, MIDI editor, and audio-to-MIDI conversion. CraftMusic AI provides four pricing tiers: Free ($0/month, 2 songs), Basic ($10.49/month, 200 songs), Standard ($20.99/month, 500 songs), and Premium ($34.99/month, 1200 songs).

About
StepAudio 3 is StepFun’s next-generation audio model family, built to understand, generate, and interact through voice, sound, and music. The lineup includes StepAudio 3 Realtime for natural full-duplex conversation, StepAudio 3 ASR for speech recognition, StepAudio 3 TTS for speech synthesis, StepAudio 3 Gen for general-purpose audio generation, and StepAudio 3 Music for long-form music creation. Realtime is designed around a continuous listen-converse-think-act loop, understanding not only words but also hesitation, laughter, emotion, pauses, backchannels, and interruptions. It can think while speaking, reason through harder questions without breaking conversational flow, and use tools to complete tasks once it understands the user’s intent. StepAudio 3 Gen unifies zero-shot TTS, voice design, vocal generation, sound effects, music, and mixed audio generation within one framework, while StepAudio 3 Music supports text-controlled songs, instrumentals, vocal arrangement, and more.
