Media Scale = How Do You Stop The Shrink to Zero

Fri Apr 24, 2020 3:19 pm

Hey fellas,

I'm a newb and for the life of me I can't figure out how to stop media from shrinking to 0px x 0px when the sound becomes quite. My goal is to post an image at a specified height and width and when the music plays it gets larger and falls back to it's original size instead of falling back to no size. How do I pull that off? I made a video explaining the issue. Thanks in advance for your help.

You need to use the Offset modifier. https://magicmusicvisuals.com/downloads/Magic_UsersGuide.html#AudioModifiers
There are examples in this section showing the use of Scale, Offset and Smooth, also how their order is significant.

Scale will alter the sensitivity to the audio.

Offset adjusts the minimum size; an Offset value of 1.0 will ensure the image size never goes below its actual size, provided the Offset modifier follows any Scale modifier.

Smooth, (also Average and Peak) will make the response less flickery.

I find Peak the most useful. It responds immediately to a peak in audio, then decays slowly.

Average and Smooth will slow down the response to any peak in the audio. The difference between them is subtle - I plotted them here

Thank you Terry!

For those wondering it's the offset modifier that does the trick.

Another option is to use the Translate module and link the Z parameter to the audio.
