# SaveAudioOpus - ComfyUI Built-in Node Documentation

> The SaveAudioOpus node saves audio data to a file in the Opus format.

The SaveAudioOpus node saves audio data to a file in the Opus format. It takes an audio input and exports it as a compressed Opus file with configurable quality settings. This node is deprecated and may be removed in future versions.

| `audio`           | The audio data to be saved as an Opus file. A ValueError is raised if this is None (for example, when the source video has no audio track). | AUDIO     | Yes      | -                                                    |
