Install and build

# Install dependencies
sudo apt-get update && sudo apt-get install libfftw3-dev

# Important to clone recursive to get unicorn-hat lib!
git clone --recursive https://github.com/daniel-j/unicorn-fft.git

cd unicorn-fft

# Compile unicorn-fft and unicorn-hat lib. Use just 'make' to build only unicorn-fft
make all

You can then try the examples examples/arecord.sh and examples/radio.sh

unicorn-fft expects a raw/PCM stream in the format Signed 16 bit Little Endian, Rate 44100 Hz, Mono

Thanks

This project uses code from raspberry-vu which is a fork of Impulse, which I base my FFTW function calls on.

Also special thanks to Damien for his guide FFT Averages, which makes it all prettier!

Issue with radio.sh example

Hi,

Great code by the way but when I try to run the radio.sh example all I get is lots of beeping instead of music and the unicorn lights up but that's it. Would you have any idea why this could be happening? Also how can I get it to work with just using audio files?

Thanks in advance.

Freezes with RPi Zero W and Unicorn pHAT

I tried this with a RPi Zero W and a Unicorn pHAT (the smaller one). It runs for a split second but then the Pi completely chokes up. It doesn't even let me get in via ssh. any hints?

Neat application, wish I could hear the sound at the same time.
