Generating sound in Flash 10

Generating sound in Flash 10

One of the new features to make it into Flash 10 is the ability to generate software-based audio. There’s essentially an event callback that will trigger during audio playback that lets you fill an input buffer full of wavelength samples. I’m looking forward to seeing what types of generative music folks will be able to create with this.

gotoAndLearn has a quick introduction to the topic that lets you tweak a waveform based on mouse position (shown above), and Andy Hulstkamp has a quick rundown on the basics of generating and modulating a specific tone. If you’re a Flash hacker, go make some bleeps and blips and send us a link to your algorythmic creations in the comments.

    Wake me when I don’t need some sodding thousand-dollar piece of Adobe bloatware to reasonably write a Flash app…

      For free development, the Flex SDK (free version) comes with the mxmlc compiler that is entirely sufficient for building a full game. This is good if you’re a codemonkey, like me, who doesn’t like mucking about with Flash’s IDEs.

        Also check out this tutorial for getting started with the free mxmlc compiler:

        The compiler is written in Java so it should work across platforms.

    Fyi, we develope an online music application. Have a look at

    You can play around with some 909s, 808s, 303s and a bunch of stompboxes which you can wire as you like.

    Have fun

    You can develop flash, flex and air apps for free using FlashDevelop, its really easy you just create a new project, get into the file and start developing.

    Don’t moan about the cost of products if you are not willing to at least look around for alternatives, they have been around for years now.
