mina socket audio wav file transfer

Because I am relatively familiar with Java, and the client is Android, I use Java for the server. Of course, other languages ​​can also be used for the server.

The main problem here is the encoding and decoding of audio wav files during the transmission process. If the encoding and decoding methods are inconsistent, the data will change. The receiving end will also change the data sent by the sending end, so the ISO_8859_1 character set needs to be used here . Encoding and decoding can ensure the correctness of data transmission.

The project is uploaded to my personal GitHub: https://github.com/qpli/AudioMinaSocket

Post a piece of core code.
