Question

I develop with Actionscript and was glad to see that AIR 2.0 was going to give access to mic input data. I planned to use this to create a visualizer set to the tempo of the incoming live audio. After doing a few days of google research it seems unlikely that it will be possible to analyze the data of the mic input in Flash/AIR. If anyone has ideas on how I can achieve this in AIR please let me know. (I’m open to workarounds.)

That being said, I don’t want to give up on the idea so I’m interested in suggestions for other language/API to use. My requirements for the app are:

• Run on OSX
• Two windows – one that can go fullscreen while the other(controller GUI) stays put
• Able to access live mic input data

I’ve done reading on FFT and understand what needs to be done on the sound side so no need to help with that.

Answer 1

I would recommend Processing.

It’s a great language (it’s java but with a lot of “help”) and a very logical next step after programming in Actionscript. Processing has a great and helpful community and there are many tutorials and libraries available.

I’ve seen several processing applications which do what you describe. Most can be found on the openprocessing site or in the exhibition section.

Also see the available sound libraries.

From the processing site:

Processing is a programming language,
development environment, and online
community that since 2001 has promoted
software literacy within the visual
arts. Initially created to serve as a
software sketchbook and to teach
fundamentals of computer programming
within a visual context, Processing
quickly developed into a tool for
creating finished professional work as
well.

If you want to give it a quick glance, just download it and open and run the bundled examples.
