iPhone应用程序：通过分析图片改编音乐（图）

一款新推出的iPhone应用程序可以通过手机摄像头捕捉周围环境色彩，并据此对音乐进行重新合成。

整个项目名为“Sadly by your side（忧伤地陪在你身边）”，是一项跨学科的艺术杰作。它包括一张专辑、一本书和一个iPhone应用程序，由大卫·开罗编写，意大利的设计和通信战略公司Fabrica制作，使用应用程序聆听其中的音乐专辑共有两种不同的方式，均需使用手机的摄像头。而如果想听原始版本的音乐，只需把摄像头对准其配书即可切换。

这款应用程序的构想是，利用摄像头捕捉周围的图像色彩信息，并将其分解为黑、蓝和红三色，每种颜色控制不同的音乐参数。根据图像信息的不同，与之对应的音乐旋律、和声、节奏、音轨等也将发生变化，从而完成根据图像数据重新合成音乐的过程。

A new iPhone app uses your surroundings to remix the music you're listening to.

"Sadly by your side" is an interdisciplinary art project encompassing an album, a book, and an iPhone app. It's written by David Cairo and produced by Fabrica, a design and communications strategy firm based in Italy. There are two different ways to listen to the album using the iPhone app, both of which require that you use the iPhone's camera. To hear the album exactly as Cairo intended it, simply hold the camera up to the book, it'll lock on, and playback the original version.

The more experimental route is to use the information hitting the camera sensor as the basis for a remix of the music.The app breaks up the image the camera is seeing into a mixture of black, blue, and red, each of which controls different parameters of the music. The underlying code for each track is programmed so that the data visualization affects the harmony, melody, and rhythm of the track differently.
