                使用须知：\n
                 1、请使用伴奏和声去除干净的人声素材，时长小于90秒，格式为mp3或wav。\n
                 2、去除伴奏推荐使用UVR5软件，B站上有详细教程。\n
                 3、条件不支持推荐使用以下几个去伴奏的网站：\n
                 https://vocalremover.org/zh/\n
                 https://tuanziai.com/vocal-remover/upload\n
                 https://www.lalal.ai/zh-hans/\n
                 4、在线版服务器为2核16G免费版，转换效率较慢请耐心等待。\n
                 5、使用此模型请标注作者：南下扶苏，以及该项目地址。\n
                 6、有问题可以在B站私聊我反馈：https://space.bilibili.com/38523418\n
                 7、语音模型转换出的音频请勿用于商业化。
