 +====== Audio Analysis in Vinyl Reality ======
  
 +===== Overview =====
 +
 +Vinyl Reality analyses the audio signal that plays through the master output of the mixer in real-time and tries to detect beats as well as the changes in the energy of the music that is playing. ​
 +
 +This data is then used to control all of the audio reactive components (ex: lights, colors, videos, etc…) in the application.
 +
 +----
 +
 +===== Beat detection =====
 +
 +Real-time beat detection in the application is mostly used to change the intensity of audio reactive components (ex: lights, screens, materials, etc..), and to control audio reactive animations, in sync with the music. ​
 +
 +Real-time beat detection is __**NOT**__ used to determine the BPM of a track!
 +
 +----
 +
 +===== Energy level detection =====
 +
 +The application tries to detect changes and short fluctuations in the energy of the music that is playing and divides them into **3 different energy levels**:
 +  * **Low:** During quiet parts of a track, for example an intro or breakdown
 +  * **Normal:** During most parts of the track where the energy remains stable
 +  * **High:** During energy peaks or fast energy increases, for example during a drop
 +
 +For example, when the music transitions from a quiet section (ex: a breakdown or intro) to a more intense part (ex: a drop), the energy level detected by the application will change from low to high. 
 +
 +These changes in energy levels are used to trigger changes in the audio reactive components in an environment,​ for example to transition the lighting colors from warm and saturated colors for a low energy level to very bright and cold colors for higher Energy Levels.
 +
 +----
 +
 +===== Limitations =====
 +
 +Because the audio analysis is done in real-time and is only used to control visual effects, the results are not always accurate and might not work well with all music genres (ex: non-electronic music).
