我建议您用 C++ 编写自己的 WAVE 文件读取器和编写器，而不依赖外部库。 WAVE 格式相当简单，至少如果您只想支持最常见的波形文件的话。
然后您将可以访问音频数据，您可以在 C++ 中轻松操作这些数据。我建议首先修改音量、通道数来计算音频的统计数据。创建音频波形的 PNG 需要一些更高级的 C++ 技能...
I would suggest for you to write your own WAVE file reader and writer in C++, without relying on external libraries. The WAVE format is fairly straight forward, at least if you only intend on supporting the most common wave files.
Then you'll have access to the audio data, which you can easily manipulate in C++. I would recommend starting by modifying the volume, the number of channels to calculating statistics on the audio. Creating a PNG of the audio waveform requires some more advanced C++ skills...

我使用 BASS 取得了良好的效果（有一个 C/C++ API 您可以使用）。
