VR Audioscape

Get it on Google Play
Google Summer of Code 2017 project: VR application built with processing-android.

made with by picorana

VR Audioscape is a VR application made with Processing. It lets you travel through a procedural landscape generated according to music. Play any music from any app on your phone, then run the app: it will automatically use as input any sound coming as output from the phone.

Table of contents



After installing the app, open any other app on your phone that is capable of playing music. Play a track of your choice, then open VR audioscape.

If music is detected correctly, the start scene will show lines representing the music being played. Look for the button that says 'Look here to start', stare at it for three seconds, and the app will start, showing the actual landscape scene.


How to compile the app from source

  • Download Processing from
  • Make sure you have Android Mode installed. If you don't, install it via selecting the Add Mode... from the menu in the upper-right corner of the PDE
  • Clone the repository on your pc
  • Open Desert_Road.pde with Processing
  • Connect your phone to your pc, enable USB debugging on your phone
  • Use Processing IDE to compile the sketch on your phone. Instructions to compile an android app via Processing IDE can be found here: Getting started with Processing for Android

Requirements for compiling the sketch:


This app is a proof of concept, meant to test and show what can be made with processing-android in VR.

Summer of Code Timeline

  • Before the start of the coding period:
    • Became familiar with the environment.
    • Discussed possible outcomes and details of the project with the mentors.
  • June 2017:
    • Made three possible sketches of how the app would be. The design attempts can be found in this repository, in the branch old_sketches. Each sketch examined a different approach at what could best fit the purpose of the project.
    • The sketch we chose at the end of this design phase had a procedural, infinite terrain. I spent the rest of the month refining the terrain, created a road and some procedural cactus.
  • July 2017:
    • Implemented reactivity to music. The musical input is taken from Android's Visualizer API. Every sound played from the phone is caught, and then processed through FFT transform and beat detection.
    • Made the terrain generation influenced by music. Now the dunes are based on volume and frequency of the music.
    • Modeled some more cacti.
    • Made the sky and
  • August 2017:
    • Made an introductive start screen.
    • Implemented day/night/cycle.
    • Various bug fixes.
    • Uploaded the app on the play store.


Many thanks to Andres Colubri and Gottfried Haider, who have been my mentors during the project, who put up with my messy code and made this possible.

Thanks to dasaki's adaptation of minim fft classes to make them work on Android and kctess5's beat detection sketch, whose work is used in this project.
