问题 Is it possible to add custom tags (say "SongKey: Em") to an mp3 file using TagLib# libary? 回答1: You can add custom tags to an MP3 by writing the data in custom (private) frames.

I am thinking about playing the MP3 silently and identify the words, but have no idea about how to do that. I am using Google Speech Engine. 回答1: There is no native way to convert an audio file that contains spoken words to text on Android. You'll need to use a third-party API to
