The MVSEP API provides programmatic access to create a separation, return the results, get site information and control user capabilities.
To use this API, you need an API key. You are not logged in, please login to get your API token.
Note that Premium users can request unlimited concurrent jobs, while non-Premium users can only request 1 concurrent job.
MVSEP runs regional API endpoints. All regions share one account database, so the same account, API key and job hashes work everywhere:
https://de.mvsep.com/apihttps://de2.mvsep.com/apihttps://hk.mvsep.com/apiRequests to https://mvsep.com/api are geo-steered: callers in Europe are routed to de, callers in North Asia to hk, and everyone else to de2. For API integrations we recommend calling a regional endpoint explicitly — it keeps the whole job lifecycle on one host regardless of where your requests originate from.
Every separation is processed and stored in the region where it was created, and the download URLs returned in responses always point to that region's host. For best performance, choose the endpoint closest to your servers and use the same host for the whole job lifecycle — create, status polling and file downloads.
You can query the status of any job from any region (the database is shared), but the output files themselves are always served by the region that owns the job.
To create separation you need to make a POST call to the following url:
https://mirror.mvsep.com/api/separation/create
| Field | Type | Description |
|---|---|---|
| api_token | String | Your API key |
| audiofile | Binary | Audiofile to be processed. Not required if url parameter is set or the model does not use file input. For matchering models use target_audiofile and reference_audiofile for input instead of audiofile. |
| url | String | Link to the audiofile. Not required if audiofile parameter is set. |
| remote_type | String | (optional) Remote type of the audiofile. Defaults to direct. Not required if audiofile parameter is set. Supported types are direct (Direct Download), mega (MEGA), drive (Google Drive), dropbox (Dropbox). |
| sep_type | Integer | (optional) Separation Type, defaults to 20. This is the separation type ID, refer to the GET SEPARATION TYPES section for more information. Ignored when <code class="higlighted">preset_id</code> is given. |
| preset_id | Integer | (optional) Run one of your saved presets over the file instead of a single algorithm. Give either sep_type or preset_id — a preset defines its own algorithms, options and output formats, so sep_type, the add_opt fields and output_format are all ignored alongside it. The response returns a hash you poll exactly like a separation; the result carries one entry per Output node of the preset. See the preset table below for your ids. |
| add_opt1 | String | (optional) Separation Type first additional field |
| add_opt2 | String | (optional) Separation Type second additional field |
| add_opt3 | String | (optional) Separation Type third additional field |
| output_format | Integer | (optional) output format, defaults to 0 (mp3 (320kbps)) |
| is_demo | Boolean | (optional) should the separation be published to demo page, defaults to false |
