非常抱歉，我之前给出的代码有误。在 Gradio 中，使用 `gr.outputs.File` 类来创建文件下载的输出组件，并没有 `mime_type` 这个关键字参数。

正确的代码应该是这样的：

import gradio as gr

def create_callback(net_g: SynthesizerTrn, tts_front: VITS_PinYin):
    def tts_callback(text, dur_scale):
        # 其他代码省略...

        # 修改下载文件的默认存放位置
        output_filepath = "/path/to/output/file.wav"  # 指定下载文件的存放路径
        return "成功", gr.outputs.File(output_filepath)

    return tts_callback

这样可以将生成的音频文件作为文件下载的输出，在 Gradio 中显示下载按钮，而不需要指定 `mime_type`。

非常抱歉给您带来的困扰，希望这次修改能够解决问题。如有任何其他问题，请随时提问！
