Spek is an acoustic spectrum analyser written in C++. It uses FFmpeg libraries for audio decoding and wxWidgets for the GUI.

I will be using WSL. Clone this repo to ~/

git clone https://github.com/Mustaali256/spek.git

Now install these prerequisites:

sudo apt update && sudo apt upgrade -y
sudo apt install libssl-dev make autoconf automake mingw-w64

Clone MXE to ~ too then cd into the directory:

git clone https://github.com/mxe/mxe.git
cd mxe/

Then add MXE to PATH by going into ~/.bashrc (or ~/.zshrc) by adding this line into the file:

export PATH=~/mxe/usr/bin:$PATH

Then you want to run this in ~/mxe:

make pthreads ffmpeg wxwidgets -j$(nproc) MXE_TARGETS='x86_64-w64-mingw32.static'

Next, run this:

cd ~/spek/
chmod +x dist/win/bundle.sh autogen.sh
./dist/win/bundle.sh

After it has been compiled, you will find the spek.zip in the dist/win/ directory, this is your binary.

On Linux it is much simpler.

Clone the repository, configure and make:

git clone https://github.com/Mustaali256/spek.git
cd spek/
./configure
make -j$(nproc)

Your spek binary will be in src/
