About
Mirelo AI is an AI-powered sound generation and editing platform designed to bring videos to life with synchronized, realistic audio. Users can upload their footage and automatically generate footsteps, impacts, Foley, ambience, and sound effects that match on-screen action, eliminating the need to search for, trim, and sync individual sounds manually. With Mirelo SFX 2.0, users can remove unwanted background music while preserving existing dialogue, generate clean sound around speech, and maintain consistent audio across multiple clips. It supports videos up to 10 minutes long, enabling users to create one coherent soundtrack for an entire edit. Its browser-based Studio provides tools to generate, extend, loop, replace, and refine audio, alongside custom background music generation and text-to-sound effects. Audio-to-MIDI functionality converts audio into editable MIDI and MusicXML files.

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.
