I am using this command on my raspberry pi:
sox -t mp3 /home/pi/Desktop/ribo.mp3 -t wav - | sudo ./pi_fm_rds -freq 94.5 -audio - Basically, it takes all the mp3 files in a directory and changes them to wav files on-the-fly, and then pipes that wav output to pifm. Is there something I can add in that would have it shuffle the files, instead of playing straight through the directory in order?
