# 上傳音頻

> 上傳音頻獲取 URL, 用於音頻相關接口

<Note>
  **中國大陸用戶請注意:** 中國大陸用戶請使用 `https://toapis.cn` 作為接口地址 (Base URL).文檔示例中的 `https://toapis.com` 請替換為 `https://toapis.cn`.
</Note>

<Note>
  **文檔 Playground 不支持文件上傳**: 請使用下方的 cURL,Python 或 JavaScript 代碼示例進行測試.
</Note>

## 爲什麼需要先上傳音頻?

1. **統一輸入方式** - 本地音頻先上傳成公網 URL, 便於後續接口複用
2. **減少重複傳輸** - 上傳一次後可以在多個請求中重複使用
