# Suno Audio Upload API Reference

> Use the Suno audio upload API to submit source audio or reference tracks for downstream music generation, cover, stem, and transformation workflows.

Upload audio to Suno to obtain a **jobId** or **music\_id** for subsequent operations.

<Callout type="info">
  * When `is_async = false` (synchronous mode):
    The API will block until processing is complete and will directly return the `music_id`.

  ⚠️ Since the full processing workflow must complete, this may take a long time.

  * When `is_async = true` (asynchronous mode):
    The API will return a `jobId` immediately.
    You need to use this `jobId` to call the [Fetch Task API](/api/en/suno/suno_fetch_v2) to retrieve the final upload result asynchronously.
</Callout>

                        - `false`: Wait synchronously for the result.

                        - `true`: Return immediately and query the result
                        asynchronously.

                          When using synchronous upload (`is_async=false`), the
                          endpoint waits and returns the audio ID directly. This
                          request may take a while.
                        example:
                          music_id: music_id
                      - type: object
                        description: >-
                          When using asynchronous upload (`is_async=true`), the
                          endpoint returns a task ID immediately. Query the
                          upload result later using `jobId`.
                        example:
                          jobId: jobId
