Hello Guys
I'm new to Teensy. Im currently using Teensy 3.2 with mini sd adaptor. What im asking is inside the SD card, it has directories.
Let's assume it has 5 directories called FILE1, FILE2, FILE3, FILE4 and FILE5. Also inside each directories it has .WAV files as Test1.wav, Test2.wav and Test3.wav
I need to analyze the FFT of each Test.wav files of each directories automatically. When the Teensy powered up it should navigate through each directories and print the FFT results on serial.
Guys i know it not a big deal. But please somebody suggest me how to do this. If there are example codes highly appreciated.

Thank you
