# Seedmusic — Full Reference

> Seedmusic is the easiest way to use the ByteDance Seed-Music model. Turn a lyric, a one-sentence prompt, or a 10-second voice clip into a finished song with vocals, stems, and a royalty-free commercial license — in under a minute.

## What is Seed-Music

Seed-Music is a unified music-generation framework released by ByteDance Research in September 2024 and documented in the paper "Seed-Music: A Unified Framework for High Quality and Controlled Music Generation" (arXiv:2409.09214). It combines three modules into one system:

1. **Auto-regressive language model** — generates full-song compositions from text, lyrics, audio references, or musical scores.
2. **Diffusion-based audio editor** — enables note-level editing inside a generated track without regenerating the song.
3. **Zero-shot singing voice conversion (SVC)** — clones a singer from only a 10-second voice or speech sample.

Seedmusic wraps these capabilities in a browser-based product so non-technical creators can use Seed-Music without code, GPU rentals, or paper-reading. Seedmusic is an independent client and is not affiliated with ByteDance.

### Pricing — https://seed-music.art/pricing

Three Seedmusic plans, all powered by the full Seed-Music model (no feature-gated quality tiers):

| Plan | Monthly | Yearly | Tracks/mo | Stems | Vocals | Commercial | API |
|---|---|---|---|---|---|---|---|
| Hobby | Free | Free | 10 | No | No | Personal only | No |
| Creator | $19 | ~$140 | Unlimited | Yes (4) | Yes (11+ lang) | Yes | No |
| Studio | $79 | ~$570 | Unlimited | Yes (4) | Yes (11+ lang) | Yes | Yes |

Yearly plans save ~40% vs monthly. Refundable within 7 days. Credit packs (one-time, valid 12 months) also available.

### Seedmusic vs Suno — https://seed-music.art/seedmusic-vs-suno

Full 2200-word side-by-side comparison page. Sections: TL;DR answer block (~150 words optimized for AI extraction), 12-row at-a-glance feature table, What is Seedmusic, What is Suno, 8-section feature-by-feature deep dive (vocal cloning, editing, stems, free tier, commercial license, languages, API, speed), pricing comparison table, "which should you choose" decision blocks, 6-question FAQ. Includes Article + FAQPage + BreadcrumbList JSON-LD.

Bottom line stated on the page: Seedmusic wins on vocal cloning, note-level editing, stems on entry plan, and API access. Suno wins on consumer polish, pop-hook quality, and cheapest entry to commercial rights at $10/month. For 100+ tracks/month or any need for stems, Seedmusic is decisively cheaper per finished licensed track.

## Seed-Music Capabilities — Full Detail

### Lyrics-to-Song (Lyrics2Song head)

Paste lyrics, choose a genre, and the Seed-Music Lyrics2Song module generates a full vocal track with consistent melody, structure, and style. The Seed-Music architecture maintains long-range musical coherence across verses, choruses, and bridges, solving the "drift" problem that breaks most AI songs at the 90-second mark.

### Prompt-to-Track

Describe the mood, genre, instrumentation, BPM, and key in plain English ("lo-fi piano with rain, melancholic, 75 BPM, Cm"). Seed-Music composes a matching instrumental track. Seedmusic ships with 40+ genre presets so you can skip prompt engineering.

### Zero-Shot Vocal Cloning (Singing Voice Conversion)

Upload a 10-second voice clip (singing or speech) and the Seed-Music SVC module generates a song in that voice. The Seedmusic UI requires a consent checkbox and applies an audible watermark on every clone to discourage misuse.

### Note-Level Editing

Most AI music tools require regenerating the entire song to fix a single note. The Seed-Music diffusion editor regenerates only the affected region. Inside Seedmusic, click any lyric line or melody segment and rewrite it; only that segment re-renders.

### Stems, Extension, and Reshaping

Seedmusic exports 4 separated WAV stems (drums, bass, melody, vocals) for mixing in any DAW. The same Seed-Music backbone can extend a 30-second clip into a full song or reshape an existing track with new instrumentation.

## Seedmusic vs Other AI Music Tools — Full Comparison

| Capability | Seedmusic | Suno | Udio | seedmusic.app |
|---|---|---|---|---|
| Powered by Seed-Music (ByteDance) | Yes | No | No | Yes |
| Permanent free tier | 10 songs/mo | Limited | Limited | 10 credits |
| 10-second vocal cloning (SVC) | Yes | No | No | Partial |
| Note-level diffusion editing | Yes | No | Partial | No |
| Stem export on entry paid plan | Yes | No (Pro only) | No (Pro only) | No (Pro only) |
| Commercial license starts at | $19/mo | Pro only | Pro only | $14.90/mo |
| Multi-language vocals (11+) | Yes | Yes | Yes | Yes |
| Open REST API | Yes (Studio) | No | No | No |
| arXiv-published underlying research | Yes | No | No | Yes |

Bottom line: if you want the Seed-Music model with a real free tier, stems on day one, and an API to integrate Seedmusic into your own product, Seedmusic is the only client that ships all three.

## Frequently Asked Questions

### Is Seedmusic the official ByteDance Seed-Music product?

No. Seedmusic is an independent app built on the publicly documented Seed-Music framework from ByteDance Research (arXiv:2409.09214). Seedmusic is not affiliated with ByteDance; it makes the Seed-Music capabilities easier to use for non-technical creators.

### Can I use Seedmusic songs commercially?

Yes. Tracks generated on the Creator and Studio plans include a full royalty-free commercial license — valid for YouTube monetization, podcasts, ads, films, and games. Users own every Seed-Music track they generate inside Seedmusic.

### What languages does Seed-Music support?

The Seed-Music model handles 11+ languages including English, Mandarin Chinese, Japanese, Korean, Spanish, French, German, and Portuguese, with native-sounding Seedmusic vocals in each.

### How does Seed-Music compare to Suno or Udio?

All three generate full songs from prompts. Seed-Music — and therefore Seedmusic — adds two things Suno and Udio do not have: zero-shot vocal cloning from a 10-second voice sample, and diffusion-based note-level editing inside generated tracks. Seedmusic is also the only Seed-Music client with a permanent free tier.

### How fast is Seedmusic generation?

A 60-second Seed-Music track typically renders in 30–45 seconds inside Seedmusic. The Seed-Music architecture is optimized for low-latency inference even at high audio fidelity, producing studio-quality output without studio wait times.
