laa

A free audio analyzer.

Welcome! If you just want to get this running (on windows, anyway), head over to Releases for the current version.

You can also find some screenshots here: https://imgur.com/a/Zj3uEW3

WINDOWS Install

Head over to the Releases for the current version.

There should be a zip with all files for windows for the current version there. If you want to build for windows, see below. It's not that easy, but quite doable.

LINUX Install/Build

Linux is where laa is written on, so naturally, building and installing should be rather easy.

Dependencies

The only dependencies of laa should be

• SDL2, >= 2.0.8
• fftw3, >= 3.3.8
• OpenGL libraries
• rtaudio, >= 5.0.0
• python3 (for building only)

Other versions might work (especially so for sdl2), so rolling release systems (arch, void, ...) should be fine.

On debian/ubuntu, you can install this with the usual methods. On debian-based systems, its something like

sudo apt install libsdl2-dev libfftw3-dev librtaudio-dev 

Getting the sources

First you need to get the sources. The easiest way is to just clone the repository with git

git clone --recursive https://github.com/mkalte666/laa.git

There are some submodule that we need. If you downloaded a release tarball, or didn't clone with --recursive then you need to run this in the project directory:

git submodule update --init --recursive

Afterwards, it should be the usual cmake workflow

cd /place/where/you/put/laa
mkdir build && cd build

# If your librtaudio < 5.1.0:
cmake -D CMAKE_CXX_FLAGS=-DRTAUDIO500=1 ..
# Else:
cmake ..

make -j
sudo make install 

WINDOWS Build

Building for/on windows can be tricky as gcc and friends tend to be a bit outated. Make sure gcc is at least 7.3! 8.1+ is strongly reccomended!

Anyway - for the windows release, the scripts under /windows are used. The basic workflow (should also work inside cygwin/msys2/...) is

• Install mingw-w64 (for x86_64-w64-mingw32-gcc and its friends)
• Install python3 (only needed for building)
• clone the repository with --recursive
• cd into windows/
• run winbuild.bash

Note that running winbuild.bash for the first time calls windeps.bash, wich downloads and builds the dependencies. This will take a bit of time. winbuild.bash also creates a release tar and zip with licences, dlls etc. copied over. If you have any trouble, or have tested out stuff from within cygwin or msys2 and can report back for that, please open a issue over here.

Thats it!

Thanks for being interested in LAA :D
