Remember, this project is an audio toy the point is to try out your own videos and Wwise events to see what noises you can produce. Note: no soundtrack needed, and any video format Unity supports should work. Photosounder is a spectral editor/synthesizer with an entirely image-based approach to sound creation and editing. I used QuickTime Screen Recording to create the included samples, but any capture method will do.

Most videos will provide interesting input for sonic experimentation. Multiple cursor positions and color averaging options are available as well.

The series of colors that generate the audio is also repeatable, in case you wanted to craft an event for a specific sequence of images. Using this version, Wwise events are controlled by moving picture, rather than by moving mouse. RTPCs are set to red/green/blue/greyscale values as before, but I added some State processing as well, whereby color values set Wwise states on a ten step scale (i.e. mov and select a position (center screen by default). VPixelSound is basically the same idea as PixelSound, except it uses video instead of jpegs. It is also possible to generate images from sounds.

If you load a picture on Photosounders interface, the software will generate a unique sound, based on the pictures visual characteristics.

There's also a Wwise Recorder instance on the Master Audio Bus, in case you want to record the output for later editing. If your download is not starting, click here.

The Wwise project contains some demonstration and test events that modify volume, pitch, trigger rates, EQ, and other parameters. This formats and resizes the picture to the screen, starts/stops the selected Wwise event, and sets the RTPCs. jpg files into the Assets/Pictures folder, then drag them into the 'Picture' field of the GetPixelParameters script attached to the 'pictureSprite' game object. Move the mouse around to hear how the event reacts to the colors and screen position. To play, fire up the Unity project, and click on the screen. This kind of 'seemingly but not really completely by chance' algorithm can be considered 'stochastic', a composition method famously utilized by Xenakis to produce interesting tonalities. You can set up patterns to trigger specific effects, or load up a photo of your dog just to see what happens. Using the color values of pixels to set Wwise event parameters is just a way to generate pseudo-random variations. Need to create some related variations for a random container? Set up a mix of assorted stems let it run while recording the output cut up the results and pick the ones you like. It's also a way to use Wwise as a sound design tool.

It's a Unity/Wwise project (partly inspired by the excellent program PhotoSounder) that loads up a jpeg, then sets RTPCs to red, green, blue, and grayscale values including x/y screen position. 'PixelSound' is an audio toy that makes a sound based on the color of the pixel your mouse is pointing at.
