Audio Visualizer

Application visualizing songs in real time.

Installation

Note that you can only compile this application on Windows in Visual Studio 2019 or newer.

Because this application is using library SFML, in order to be able to compile the code some libraries are needed. Those should be added automatically. If not, you have to add openal32.dll, sfml-audio-2.dll, sfml-graphics-2.dll, sfml-system-2.dll, sfml-window-2.dll to the Release folder. Respectively, sfml-xxx-d-2.dll to the Debug folder. You can find those files in SFML-2.5.1 folder. You do not have to setup includes, header and libraries paths in visual studio. That is already done in configuration file for Visual Studio.

Using the application

Main menu

In main menu you can choose one of the songs from the database and one of the visualizing modes. Currently selected song and mode are highlighted. If there is more than six songs in the database you can list using triangles under the column with song names. After clicking Play chosen song will be visualized with chosen mode. The plus button serves the purpose to add new songs. See* Adding new songs* section.

Adding new songs

Note that the only accepted format is .wav and .flac.

If you want to add new song, you have to manually add the song in .wav or .flac format to Resources/Songs file. Then you can either write its name into the song_database.txt. Or click on plus button at main menu screen and write its name into the Console.

Note name that you write either to the song_database.txt file or Console must be exactly the same as name of the song you added to the Resources/Songs file.

Modes

At each Mode screen there is triangle button at the top left corner that quits the play mode and enters the menu.

Amplitude mode

This mode shows raw frequency waves.

Radio mode

This mode visualizes the song as bars. Each bar represents specific frequency and its height represents its loudness.

Map mode

This mode creates a map that moves with time. Map is generated similarly as radio mode is.

Space mode

This is the most complex mode. Stars speed is linked to sub bass frequencies. Planet size is mapped to human voice frequencies. Rotation of the planet is mapped to high pitch frequencies. And lastly halo is radio mode-like representation of bass frequencies.
