Audio Layer Confusion
Alright, this isn’t making any sense to me… I have this expression applied to an audio layer’s audio levels:
l = thisComp.layer("Flash").transform.opacity.smooth(.2, 3);
x = linear(l, 0, 100, -72, 10);
[x,x];
And the dB appear to change correctly when i scrub through the timeline, but whenever I preview the composition the audio plays back at a steady 0dB. When I remove the expression I can keyframe the dB and it works properly, but this expression seems to be causing trouble.
Is there something obvious I missed in writing this out?!

It’s a mystery to me. If you look at the graph, it appears to be working, but it doesn’t show up in ram or audio preview. Strange.

So you were able to recreate the problem? I thought maybe something had become corrupted in my project, because it was working earlier with a different audio file, but if it’s not working for you then I’ve lost all hope =O

I did repro it. And I could swear I’ve done stuff like this before. But….. it works in AE 7. Apparently something happened in CS3.

Apparently applying Time Remapping to the layer fixed the problem… and I have no idea why. I didn’t change any of the time remap values, just applied it to the layer and presto: back in business.

Make sure you file a bug so the AE team is aware of the problem and queue’s it to be fixed.
