About

Remix artists can now juggle vocals and instrumentals like a circus performer on caffeine. And for those of us who've always wondered what our favorite songs would sound like if the drummer mysteriously vanished mid-performance, Spleeter has got you covered. Whether you're a professional producer or just someone who enjoys musical Frankenstein experiments, Spleeter opens up a world where every song is a musical LEGO set, ready to be taken apart and reassembled at will. Use clean vocal tracks from Spleeter Online as input for AI voice conversion tools, allowing you to transform vocals into different styles or mimic other voices with high accuracy for unique audio projects. Convert isolated instrumental tracks into MIDI files, enabling you to recreate, edit, or remix melodies and harmonies in your preferred digital audio workstation (DAW) with ease. Extract vocals from tracks and use voice-to-text software to generate accurate transcriptions for lyrics, interviews, or podcasts.

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.
