--- title: MiniMax Music Cover | Runware Docs url: https://runware.ai/docs/models/minimax-music-cover description: Audio-to-audio song transformation that preserves melody while changing style --- # MiniMax Music Cover MiniMax Music Cover is MiniMax’s song-to-song transformation model for reimagining an existing track in a new style. It preserves the original vocal melody while changing voice timbre, instrumentation, genre, and arrangement through a text prompt. It supports one-step generation from reference audio or a two-step workflow with preprocessing and optional lyric editing. - **ID**: `minimax:music@cover` - **Status**: api-only - **Creator**: MiniMax - **Capabilities**: Audio to Audio ## Request Parameters **API Options** Platform-level options for task execution and delivery. ### [taskType](https://runware.ai/docs/models/minimax-music-cover#request-tasktype) - **Type**: `string` - **Required**: true - **Value**: `audioInference` Identifier for the type of task being performed ### [taskUUID](https://runware.ai/docs/models/minimax-music-cover#request-taskuuid) - **Type**: `string` - **Required**: true - **Format**: `UUID v4` UUID v4 identifier for tracking tasks and matching async responses.

The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials. **Common use cases:** - **Cloud storage**: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs. - **CDN integration**: Upload to content delivery networks for immediate distribution. ```text // S3 presigned URL for secure upload https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600 // Google Cloud Storage presigned URL https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789 // Custom storage endpoint https://storage.example.com/uploads/generated-image.jpg ``` The content data will be sent as the request body to the specified URL when generation is complete. ### [ttl](https://runware.ai/docs/models/minimax-music-cover#request-ttl) - **Type**: `integer` - **Min**: `60` Time-to-live (TTL) in seconds for generated content. Only applies when `outputType` is `URL`. ### [includeCost](https://runware.ai/docs/models/minimax-music-cover#request-includecost) - **Type**: `boolean` - **Default**: `false` Include task cost in the response. ### [numberResults](https://runware.ai/docs/models/minimax-music-cover#request-numberresults) - **Type**: `integer` - **Min**: `1` - **Max**: `4` - **Default**: `1` Number of results to generate. Each result uses a different seed, producing variations of the same parameters. **Inputs** Input resources for the task (images, audio, etc). These must be nested inside the \`inputs\` object. ### [audio](https://runware.ai/docs/models/minimax-music-cover#request-inputs-audio) - **Path**: `inputs.audio` - **Type**: `string` - **Required**: true Audio input (UUID or URL). **Generation Parameters** Core parameters for controlling the generated content. ### [model](https://runware.ai/docs/models/minimax-music-cover#request-model) - **Type**: `string` - **Required**: true - **Value**: `minimax:music@cover` Identifier of the model to use for generation. **Learn more** (3 resources): - [Text To Image: Model Selection The Foundation Of Generation](https://runware.ai/docs/guides/text-to-image#model-selection-the-foundation-of-generation) (guide) - [Image Inpainting: Model Specialized Inpainting Models](https://runware.ai/docs/guides/image-inpainting#model-specialized-inpainting-models) (guide) - [Image Outpainting: Other Critical Parameters](https://runware.ai/docs/guides/image-outpainting#other-critical-parameters) (guide) ### [positivePrompt](https://runware.ai/docs/models/minimax-music-cover#request-positiveprompt) - **Type**: `string` - **Required**: true - **Min**: `10` - **Max**: `300` Text prompt describing elements to include in the generated output. **Learn more** (2 resources): - [Text To Image: Prompts Guiding The Generation](https://runware.ai/docs/guides/text-to-image#prompts-guiding-the-generation) (guide) - [Image Outpainting: Other Critical Parameters](https://runware.ai/docs/guides/image-outpainting#other-critical-parameters) (guide) ### [seed](https://runware.ai/docs/models/minimax-music-cover#request-seed) - **Type**: `integer` - **Min**: `0` - **Max**: `1000000` Random seed for reproducible generation.
