You can automatically play your WAV files in random order using time-delayed settings, though this program's configurations aren't readily comprehensible.
RandoMaster 2 requires no installation, and its boring interface lacks appeal. The program effectively plays the WAV files located in the directory of your choice in random order. You can select how often the program chooses a file to play and the duration of time between play by adjusting its probability settings. RandoMaster 2 silently resides in your system tray, and you can disable the program on the main window without actually shutting it down.
While we like this simple program's overall effectiveness, it could use simpler configurations to determine play instances rather than probability settings. Although its name is randoMaster, the option to specify the order the files are played in might broaden its usefulness. This free software is good for random, automated play, but it certainly doesn't top the list of user-friendly programs.
