Flutter：有音频分析的软件包吗？
现在我需要开发一个应用程序，它可以分析音频并提取其频率和比特率。我开发了选择 mp3 或 m4a 音频并将其放入应用程序的功能。那么有没有 dart 包可以帮助我分析音频并提取频率和比特率？
感谢您的帮助。

Thanks for your help.

对于flutter当前来说，这种高级功能包并不多。
我找到了一个用于从 mp3 文件获取比特率、采样率、CRC 检查、持续时间等的包。您可以检查并尝试一下。 MP3 Info
否则你必须在android、ios等平台上编写代码来提取比特率和频率以及将这些代码桥接到 dart/flutter，以便您可以从 flutter 应用程序调用这些代码。
For flutter current this kind of advanced featured package is not much available.
I found a package for getting bitrate, sample rate, CRC check, duration etc. from a mp3 file. You can check and try it out. MP3 Info
Otherwise you have to write code on android, ios and other platforms code for extracting bitrate and frequency and bridge those code to dart/flutter so that you can call those code from your flutter application.
