探索目录ASLP Lab: DiffRhythm
aslp-labDiffRhythm is a diffusion-based lyrics-to-song model that creates vocals and accompaniment together. Structured lyrics establish the song, while a style description and optional reference audio guide its musical character. Its official model page describes a ninety-five-second standard mode and a 285-second extended mode, allowing either a shorter demo or a more developed composition. Verse and chorus sections help communicate the intended song layout. Use cases: lyric demos, reference-guided songwriting prototypes and full-song soundtrack sketches built around an existing set of words.
ACE Studio & StepFun: ACE-Step Prompt
ace-stepACE-Step Prompt offers a natural-language workflow for the ACE-Step music foundation model. A brief can describe the scene, genre, mood and intended character of a song in one place, supporting both vocal and instrumental music. It is useful for exploring an idea before writing a separate lyric document; creators with fixed words can use the companion tags-and-lyrics version. Seed and requested-duration controls support repeated exploration of the brief. Use cases: exploratory song concepts, mood-led compositions and instrumental background cues.
ACE Studio & StepFun: ACE-Step
ace-stepACE-Step is an open music foundation model co-led by ACE Studio and StepFun. Its diffusion-based architecture combines a compressed audio representation with a lightweight linear transformer, with the technical report emphasizing musical coherence and alignment between sung words and music. This version accepts style tags and optional lyrics as separate creative inputs, giving songwriters explicit control over the musical palette and words. Seed and duration controls also support instrumental compositions. Use cases: lyric-led song sketches, genre-tag exploration and music built around a defined song structure.
Stability AI: Stable Audio 3 Medium Base
stabilityStable Audio 3 Medium Base is the foundational 1.4-billion-parameter checkpoint for the family's longer stereo music compositions. It is the unmodified underlying checkpoint in the Medium family. A text brief can establish instruments, atmosphere and an arrangement that develops across the piece, while seed, negative-prompt and duration controls guide generation. Its Base identity is useful when evaluating the underlying model alongside adapted versions. Use cases: baseline long-form composition experiments, cinematic instrumental sketches and comparative studies of musical prompts.
