Installation

Make sure FFTW is installed:

sudo apt-get install libfftw3-dev

Make sure CMake is installed:

sudo apt-get install cmake

Create a bin folder and select it:

mkdir bin
cd bin

Run CMake:

cmake ..\

Compile:

make

Test speed

In the bin folder:

./test

This will take some time (few tens of seconds max), and print the performance in the terminal.

Perform DoA estimation

Assuming the audio in.wav contains as many channels as the number of microphone of the arrays (choose between respeaker_usb, respeaker_core, minidsp_uma and matrix_creator), run the following command:

./ssl -i in.wav -a respeaker_usb -m smp -o out.csv

The estimated DoA will be written in CSV format to the file out.csv.
