these 2 seem animated by manually keyframing to me.
somethhing about audio to keyframes rather than waves:
but you'd need the plug-in from trapcode for this.
my suggestion would be to do it "by hand", keydframing the animation to the souund.
if it's just a bouncing circle, you're probably faster to keyframe position&size, maybe anchor aswell by feeling than to type endless expressions.
anmd if it's more complex, like the kinetic text example, you have more control over the movement than the Bass and Trebles do.
See this page for resources about using audio levels to drive animation:
You do not need Trapcode SoundKeys to do this, though that plug-in does make some aspects much easier.
