Play and sox are two important commands in Linux. The play command can be used to play a variety of music files, and sox can be used to edit a variety of files. I tried these two items first yesterday and it was very convenient and helpful.

On the Ubuntu Desktop, press Ctrl + F1 to enter the command line mode in Linux.

The common function is to listen to music. Input play [musicFilename] And musicFilename can be mp3, ogg, and other music files, however, Microsoft's wma does not seem to be able to recognize the effect of Q's playing music. It does not offer music software on other graphical interfaces at all, and in the command line mode, during music playback, play also provides basic information about music files, such as the frequency and playback time.

The sox command is very powerful. I thought that in Windows, I would like to download the software by bringing two pieces of music together. Many software versions are still trial versions, which is quite uncomfortable.

Now you only need to enter sox
Music1Filename music2Filename

ResultFilename, where music1Filename and music2Filename are source music files and resultFilename are the music files you want to convert to. This way, you can convert two music files into one. Sox has many more powerful functions. Let's take a look at it using man and sox commands.
