谷歌Logo标题声音节奏动画AE MG教程 Google Sound Response Animation

谷歌新Logo色块随音频跳动动画，将音频转换成关键帧，然后链接到线条长度变化中

we’ll be creating sound activated shape layers inspired by the new Google animations for the new logo using After Effects.

教程中用到的表达式：

第一个:
aInp=thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);
aInp.valueAtTime(time-(index/24))*4+.000­1

第二个:
inp=content(“Shape 1″).content(“Trim Paths 1″).start;
linear(inp,0,100,180,0);
