Stable Audio is the strongest fit for open-weights, full-song composition, while Diff-SVC is the specialist choice for changing a singing voice’s timbre. Those are the two options in this roundup because the verified information available establishes an open-weights music composer and an AGPL-3.0 singing-voice-conversion model. They solve different jobs, so choosing between them depends on whether you need a newly composed song or a transformed vocal performance.
What “Open-Source AI Music Model” Means Here
“Open-source” can describe different release arrangements. For Stable Audio, the verified description says that weights are available to download and describes the system as open-source. For Diff-SVC, the verified project information identifies an AGPL-3.0 license. The available evidence does not establish identical permissions, model checkpoints, installation steps, hardware needs, supported operating systems, audio formats, or commercial-use terms for both projects.

A phone can be the device you use to write prompts, organize source recordings and review exported audio, but the supplied facts do not establish a native Android app or an on-device version for either model. Check each project’s current documentation before planning a phone-only workflow. If you generate or convert audio elsewhere, you can then copy the resulting files to your phone for listening, trimming or sharing with apps that support the file type.

|---|---|---|---|---|

| Diff-SVC | Singing voice conversion into a target timbre, with basic pitch correction | Public GitHub project | AGPL-3.0 | Not stated |
Use the table as a starting filter rather than a compatibility guarantee. “Not stated” means the supplied evidence does not establish that detail; consult the linked project before installing, publishing or monetizing audio.

1. Stable Audio
Stable Audio ranks first for a reader who wants an open-weights model aimed at composing a complete song. The verified description specifically says “Full song composition with open-weights availability,” and the product page states that the weights can be downloaded. That makes it the clearest match for the phrase “open-source AI music model” in this limited, evidence-based list.
Why It Fits Full Song Composition
A full-song workflow starts with musical intent rather than a pre-existing vocal. You might define the mood, instrumentation, approximate structure and energy in your prompt, then create a draft to evaluate on your Xiaomi phone. The evidence confirms the full-song composition purpose, but it does not establish a particular genre library, vocal mode, duration limit, stem export, sample rate, interface, hardware requirement or mobile app. Treat those as questions to verify on Stability AI’s current page.

A Practical Prompt And Review Workflow
- Write a compact brief describing the song’s intended mood, arrangement and listening context. For example, specify an atmospheric instrumental intro, a stronger central section and a restrained ending without claiming that any particular structure is guaranteed.
- Run the prompt in the supported Stable Audio environment described by the vendor. The available facts do not establish whether that environment is local, hosted, or available directly on Android.
- Move the resulting audio to your Xiaomi, Redmi or POCO phone and listen with headphones and the phone speaker. Mark moments where the arrangement becomes crowded, the lead element loses focus or the ending feels abrupt.
- Revise the brief by changing one musical idea at a time. Keeping a short version history makes it easier to compare drafts without assuming that a later generation will preserve every earlier detail.
- Before release, read the current Stable Audio terms for ownership, commercial use, datasets and any restrictions on voices or source material. Those legal and licensing details are not established in the supplied facts.
Best Fit And Limits
Choose Stable Audio when the deliverable is a newly composed song or a song-like instrumental draft. It is less clearly suited to a voice-conversion task because the verified description does not establish singing-voice timbre conversion. Do not assume that downloadable weights automatically answer every redistribution or commercial-use question; confirm the applicable terms at the source.
2. Diff-SVC
Diff-SVC ranks second because it addresses a narrower but important music-production problem: “Singing Voice Conversion via diffusion models.” The verified project description says it converts input singing voices into a target timbre and supports basic pitch correction. Its stated AGPL-3.0 license is the clearest licensing fact in this roundup.

Why It Fits Vocal Timbre Conversion
Diff-SVC is for a workflow that already has a singing performance. You provide an input singing voice and seek a different target timbre, with basic pitch correction available according to the project description. That is fundamentally different from asking a model to compose an entire song from a text brief. The available evidence does not establish whether it generates accompaniment, writes lyrics, creates melodies from text, separates stems, or provides a finished mastering chain.
A Consent-First Conversion Workflow
- Record or prepare a singing performance for which you have permission to use the voice. Keep the source files organized so you can identify the singer and the session associated with each conversion.
- Choose a target timbre only when you have the necessary consent and the target use follows the project’s terms and any other applicable permissions. A model’s technical ability does not grant permission to imitate a person.
- Use Diff-SVC in the environment supported by its repository. Android availability, installation method, hardware needs and audio-format support are not stated in the supplied facts, so check the GitHub documentation before planning around a Xiaomi phone.
- Review the converted vocal for pitch problems and unwanted changes in tone. The project description establishes basic pitch correction, but it does not promise a particular accuracy level or a specific musical style.
- Read the repository’s AGPL-3.0 licensing information and any model or dataset notices before distributing software, weights or recordings. Also check the consent and usage terms attached to every voice used in the project.
Best Fit And Limits
Pick Diff-SVC when your central task is changing the timbre of an existing singing voice. It is not established as a general text-to-song composer, so it should not be ranked as a replacement for Stable Audio when you need a complete composition. The facts also do not establish commercial permissions for particular converted recordings; verify those conditions before publication.

Which Model Should Xiaomi Users Choose?
- Choose Stable Audio if you want to start from a musical brief and produce a full-song composition with downloadable weights available.
- Choose Diff-SVC if you already have a singing performance and need conversion into a target timbre with basic pitch correction.
- Check the vendor documentation first if Android support, local execution, file formats, performance requirements, commercial release, voice consent or model redistribution affects your decision. Those specifics are not established for both tools here.
Rights And Safe Publishing Checks
Voice conversion requires permission from the people whose voices are recorded or imitated. Obtain consent before processing a singer’s performance or selecting a recognizable target timbre, and follow each project’s current terms. For Stable Audio, the supplied facts confirm downloadable weights and full-song composition but do not state a license or commercial-use policy. For Diff-SVC, AGPL-3.0 is stated for the project, while permissions for particular voice models, datasets and recordings still need checking. Keep a record of the source files, permissions and version of the software used for each release.
Bottom Line
Stable Audio is the better first stop for open-weights full-song composition. Diff-SVC is the focused option for converting a singing voice into a target timbre and applying basic pitch correction. Because the verified evidence covers only these two tools and leaves mobile, hardware, format and commercial details unstated, confirm those points on the linked sources before building a Xiaomi phone workflow or publishing the result.
