如何在不使用Aubio的情况下获得a.wav文件的平均音高？

Question

所以，我正在开发一个程序来比较不同.wav 文件的平均音高。 我找到了一个解决方案，它使用 aubio 在 repl.it 上工作，但由于某种原因，每次我执行pip install aubio时都会出现大约 50 条红线错误。 关于车轮构造的一些东西不起作用。 那么，没有奥比奥有什么办法吗？

这是我的错误信息：

一些附加信息：

• 我正在使用最新版本的 Python 3
• 我正在使用 windows
• 我确保让安装程序安装路径变量
• PIP 已安装
• 当我使用更新命令检查 Wheel 版本时，它说它已经是最新版本。

Answer 1

您不应该只是尝试使用 pip 命令，因为它并没有真正构建文件。

步骤 1) 下载 aubio 的 tar.gz。 最新版本是 0.4.9，所以一定要下载。

步骤 2) 提取 tar.gz

步骤 3) Go 到您的命令提示符/终端，然后 cd 进入解压创建的文件夹。

步骤 4) 执行 python./waf 配置命令提示符。 这使您的文件准备好进行配置。 确保已经有 C++ 编译器。 我使用了 Visual Studio 的 MSVC。 接下来，在命令提示符下执行 python./waf build。

第 5 步）您现在应该可以毫无问题地执行 pip 安装 aubio，并且它应该正确安装到您的计算机上。
