These were taken from the Apple sample project avTouch, and will be explained later on in this tutorial.įirst, extract the downloaded project, open it in Xcode, and build and run. The MeterTable.h and MeterTable.cpp C++ files were also added to the project.
An image named particleTexture.png was added to the project for use by the particle system. It contains a method which allows you to pick songs from your iPod library. The amework has been added to the project. The supported interface orientation is set to landscape. It provides a simple user interface for the application. The starter project has the following functionality: To start things off, download this starter project. Note: You can try out most of the tutorial using the iPhone Simulator, but you will need to run the project on a device to select different songs and to play the music in the background. So cue up the music and break out the disco ball, things are about to get visual! You’ll also learn how to make those particles dance to the beat of a song. You’ll learn how to configure the project to play music as well as support background audio and to create particle effects using UIKit’s particle system. In this tutorial, you’ll create your very own music visualizer. To see an example of music visualization in action, simply launch iTunes, start a good tune, then choose View/Show Visualizer and allow the psychedelics to free your mind! :] Now, music visualization is a common technology that can be found in almost every digital media player such as iTunes or Windows Media Player. The device was a market failure but it was the first time that the world was exposed to music visualization. Consumers could manipulate the images by twisting knobs and pushing buttons on the device. In the mid-seventies, Atari released the Atari Home Music player that connected a television to a stereo and thereby produced abstract images in sync with the music.
