I'm following this tutorial to create a music visualizer. I adapted the Arduino code to run with the Adafruit 32x16 LED matrix, which seems to work. But I'm getting errors with the FFT itself. The code I am using can be found here:

I am getting this error:
Code: Select all
==== JavaSound Minim Error ====
==== Unable to return a TargetDataLine: unsupported format - PCM_SIGNED 44100.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian
=== Minim Error ===
=== Minim.getLineIn: attempt failed, could not secure an AudioInput.
I've looked around for a while and cannot seem to figure it out. I believe it is a setting I have on my computer that is preventing Processing to access the audio, but I really don't know.
