Microphone Sound Spectrum now Included in Woodpecker Open Source ActionScript 3 Classes


The microphone is now supported in the Woodpecker open source ActionScript sound spectrum classes.  Just download the zip file and see the mic example.

You need to make a Microphone object in your file (as shown in the sample) and then pass the fact that you want to use the mic as the last parameter to Woodpecker.

var myMic:Microphone = Microphone.getMicrophone();
var mic:Boolean = true;
new WoodPecker(clip, type, num, size, freq, dragable, mic);


WOODPECKER – Flash Sound Animation Classes Examples

“It was unbelievable to see Woodpecker animate mouths to audio!”

Woodpecker animates DisplayObjects to sound frequency or wave forms. It is a wrapper file for the ComputeSpectrum in Flash which is quite tricky and provides many options for designers to help them animate any number of clips to sound for visualizations and lip synching or moving objects in a scene based on ambient sounds.

Microphone Spectrum Support in Flash CS5

Wow!  What a great release – Adobe Flash Player 10.1 / Adobe Flash CS5:



1. Multitouch (Goose)
2. Compute Spectrum on the Microphone (Woodpecker)
3. Accelerometer (Penguin)


In past versions of Flash, we have only had sound frequency and waveform data for MP3 and FLV’s in Flash.  We only had the throughput (similar to volume) for the microphone.  In Flash 10.1 we can now animate to frequency and wavelength of microphone input!  This is amazing!!

We can now use Woodpecker to:

animate to live bands!
animate to people talking in a room!
animate to live chats!

Download Woodpecker Sound Animation Classes for Flash and try it out!

All the best!
