    If you only use the ‘Convert Audio To Keyframes’ (instead of SoundKeys) assistant, it creates a brand new Audio Amplitude layer with all the keyframes from the audio. Now, you only need a simple expression to link these keyframes to any property of a layer. (See the manual.)

    Add an expression to the property of your choice by Alt+clicking on the stopwatch, and then use the pick whip to link this property to the ‘Audio amplitude’ layer.
