This happy sound and music visualisation app converts sound frequencies into light/colour frequencies, in the most scientifically accurate visualisation process available on iOS. Will you find the aliens?

Special Features:
- Many geometries to explore the colour of your sounds
- Mood light mode for music-responsive ambient light projection
- Science page to learn more about our senses
- Secret modes to unlock

1: The visualisation will begin immediately. Speak to your device or play music. Select different geometries with 2 fingers.
2: Instructions are included in the app, you can access them any time with two fingers.

The art of synesthesia:
As trippy psychedelic synesthesia art, this app is an exploration of the relationship between our audio and visual senses, and the nature of our consciousness.

The science of the senses:
Your eyes contain 3 colour receptive cells, each having different sensitivities within the perceptible light spectrum. At the same time, your ears have different sensitivities over the audible spectrum. In addition, our eyes and ears re-adjust depending on the intensity of light and sound. Using real data on the nature of our sensory organs, the ambient sound spectrum picked up by your device's microphone is converted into light in real-time, so you can for the first time see the colour of your voice, music, nature and environment.

This app forms part of a larger project of synesthesia and sound visualisation. For more information, apps and more details about the science involved, please visit the blog site:
If you would like to contribute music for a future release, or use this process in your own projects, live performances, VJ sets, or other, please send me an email.

Bit disappointed

I got this thinking I could visualize my music, which technically I can, but only if I play it through the iPhone speaker so that the iPhone mic picks it up. Please add an option to react to the iPhone audio directly so not only can I use it with headphones, but so it receives a high quality, accurate representation of the music.

I was surprised at how good this was! Very responsive to sounds. As a long time user of Winamp's Milkdrop, I enjoy seeing my music and encourage the developer to continue developing Soundcolour's patterns. Many thanks.


Wonderful app

This is one of those apps that pushes the envelope on what is possible with mobile phones and technology. Thank you Dr. Outram for developing awesome apps like this.
