summary: Convert to WAV Format
deprecated: false
description: >-
Convert an existing music track to high-quality WAV format.
### Usage Guide
- Use this endpoint to obtain WAV format files from your generated music
- WAV files provide uncompressed audio for professional editing and
processing
- Converted files maintain the full quality of the original audio
### Parameter Details
- `taskId` identifies the original music generation task
- `audioId` specifies which audio track to convert when multiple
variations exist
### Developer Notes
- Generated WAV files are retained for 14 days
- WAV files are typically 5-10 times larger than MP3 equivalents
- Processing time may vary depending on the length of the original audio
