About

Audjust AI is an AI audio editor and music generator built to shorten songs, lengthen audio, find seamless loops, and create music from text or lyrics. It helps users edit existing audio files with professional results in seconds, using smart audio technology that preserves natural endings, musical structure, transitions, and flow instead of producing awkward cuts, abrupt endings, or simple fadeouts. Users can upload common audio formats such as MP3, WAV, M4A, OGG, and FLAC, choose whether they want to shorten, extend, or loop a track, and let the AI identify optimal edit points automatically. Precision Audio Length Control transforms any song to the desired duration while maintaining musical integrity, making it useful for social media, video projects, background music, and professional audio work. AI-powered loop detection scans a track, analyzes musical patterns and transitions, and instantly finds seamless loop opportunities for sampling, remixing, and content creation.

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.
