Amplitude Xtra

Amplitude Xtra Publisher's Description:
The Amplitude Xtra 3.0 allows Macromedia Director movies to respond in real time to the amplitude data derived from sound cast members. The xtra sends a continuous stream of amplitude values to Director while a sound is playing.

This means that you can,

* synchronize sprite animations and properties to sounds in Director
* draw sound waveforms using normal Director sprites in real time at any resolution
* achieve lip-sync between animated characters and spoken dialogue
* change inks and blend properties in time with sound and music
* create sound visualizations based on amplitude intensity using Imaging Lingo or Shockwave 3D.

The Amplitude xtra,

* works with internal sound cast members (including SWA and MP3)
* works with externally linked WAVE, AIFF, SWA and MP3 files
* works with Director 8.5 to 11
* is cross-platform (Windows, MacOS X Universal Binary and Carbon)
* is safe for use with Shockwave
* works with streaming Shockwave audio

What's new in this version:

* compatibility with Director 11 and Shockwave 11
* a Universal Binary version of the Macintosh xtra that runs natively on Intel and PPC Macs
* compatibility with Windows Vista
* backwards compatibilty with Director 8 - 10.x on both Windows and Macintosh platforms
* enhanced control of amplitude smoothing
* support for sound members using 48KHz sample rate
* support for MP3 files using Variable Bit Rate (VBR) and Joint-Stereo encoding
