# Upload Audio and Choose an Action

Bring your own recording into the AI Music Generator, then extend it, cover it, add vocals or an instrumental, replace a section or mash it up — and which action needs which kind of source.

The AI Music Generator can start from a recording of yours instead of a text description. An uploaded song lands in My Music like a generated one, and every remix action works on it.

## Upload a recording

1. In the generator, choose **Audio** (Use your own audio).
2. Drop a file or click to upload. Accepted: MP3, WAV, OGG, AAC, FLAC and M4A, up to 50 MB and up to 8 minutes.
3. Choose what happens next:
   - **Upload only** adds it to your library to extend, cover or add to later.
   - **Create from audio** opens it straight in a cover or an extension.

Uploads are checked against known recordings. A file that matches an existing commercial recording is refused, so use a recording you made or have the rights to.

## The actions, and what each needs

Open the song's **Remix** menu (or pick it as the source in the generator) and choose an action. Each one creates a new version; the original song is kept.

| Action               | What it does                                             | Source it needs                      |
| -------------------- | -------------------------------------------------------- | ------------------------------------ |
| **Extend**           | Continues the song from a point you choose.              | Any song or upload                   |
| **Cover**            | Re-performs the song in a new style, keeping its melody. | Any song or upload                   |
| **Add vocals**       | Writes and sings a vocal over the music.                 | An instrumental                      |
| **Add instrumental** | Builds a backing track under the voice.                  | A vocal track                        |
| **Replace section**  | Rewrites one part of the song with new lyrics.           | A vocal song whose full lyrics exist |
| **Mashup**           | Blends two songs into one new track.                     | Two songs                            |

If an action is greyed out, the song is the wrong kind of source for it — for example, Add vocals on a song that already has a vocal. Songs made with an earlier version of the music engine can be played and downloaded but not used as a source.

Each action is a generation and draws credits like one; the button shows the cost before you start, and [Credits and Plans](https://aimusicis.com/docs/getting-started/credits-and-plans) lists every rate.

## Tips for a clean result

- Upload the cleanest version you have. Hiss, clipping and room noise are carried into an extension or a cover.
- For **Add vocals**, an instrumental with a clear structure (intro, verse, chorus) gives the vocal something to follow.
- For **Add instrumental**, a dry vocal without reverb or a backing track works best; run the [AI Vocal Remover](https://aimusicis.com/ai-vocal-remover) first if your recording has music under it.
