Remaster Music APIUpgrade Song Quality
Upgrade the quality of a song you already made. Pass a clip id, choose how much to vary the result, poll for the remastered track, and download — with API keys, free trial credits, pricing, and production-ready docs.
What is the Remaster Music API?
It's the /sonic/create endpoint with task_type: remaster. Point it at an existing song by continue_clip_id, pick a model version, and optionally set variation_category on sonic-v5 to control how much it changes.
- Higher Fidelity
Upgrade an earlier generation to a cleaner, higher-quality version with one call.
- Control the Variation
variation_category— subtle, normal, or high — sets how far it strays.- Same Create Flow
Reuse the create + poll integration you already have — just a different task type.
API Examples
Remaster a song by clip id, then poll for the upgraded track.

Remaster Music API: Pricing, Free Access & API Keys
Developers adding a remaster step usually want three answers: how to test for free, how to get an API key, and how cost scales after the prototype works.
Free trial
Use free credits to test remastering before choosing a paid plan.
Pricing
Credit-based. Estimate per-track cost on the pricing page.
API keys
Generate a bearer token in your account, keep it server-side, and call the create and task endpoints.

Frequently Asked Questions
Everything you need to know about remastering songs with the API.
What is a remaster music API?
A remaster music API upgrades the quality of a song you already generated. With MusicAPI you POST to https://api.musicapi.ai/api/v1/sonic/create with task_type 'remaster', the clip id of the song, and a model version, then poll the task endpoint for the upgraded track.
How do I remaster a song with the API?
Call /api/v1/sonic/create with task_type 'remaster', continue_clip_id set to the song's clip id, and a model version (mv). On sonic-v5 you can pass variation_category ('subtle', 'normal', or 'high') to control how much the remaster changes the track. Then poll GET /api/v1/sonic/task/{id}.
What does variation_category control?
On sonic-v5, variation_category sets how far the remaster moves from the original: 'subtle' keeps it close, 'normal' is a balanced upgrade, and 'high' allows more change. Use subtle when you only want a cleaner, higher-fidelity version.
Which songs can I remaster?
Remaster works on a clip referenced by its clip id — typically a song you generated with the create endpoint. Pass that id as continue_clip_id along with the model version.
How long does a remaster take?
Remastering is asynchronous: the call returns a task id immediately and usually finishes in about 1-3 minutes. Poll the task endpoint every 15-25 seconds until the status is complete. Polling task status is free.
How is remaster pricing handled?
Remastering uses credit-based pricing. Test with free trial credits, estimate cost on the pricing page, and upgrade as volume grows. Failed upstream tasks are auto-refunded.
Do remastered tracks include commercial rights?
Yes — audio produced through the API comes with commercial rights included, so you can ship remastered tracks in apps, games, videos, and client work.
