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.

About
Vocals should sound perfectly in tune, but undoctored. You obtain vocal tracks that are as perfect as you could wish, yet sound as though they’d never been touched. Using a groundbreaking method, the system significantly improves the audio quality, providing a crystal-clear listening experience with reduced fatigue. By compressing the dynamic range, the audio maintains a more consistent volume level, which prevents listener fatigue and keeps the audience engaged, especially in situations with background noise or when the listener's attention may be divided. Your files stay safe and secure right where they belong - on your machine. We prioritize your security with local processing and zero server uploads.
