Add an envelope modifier to the baked fcurve to remap to your desired range.
Another way, and one I use extensively in my sound drivers addon, is to bake the sound to a custom property
prop, then set up a driver ,
SCRIPTED EXPRESSION type, with the baked property as a variable (
'["prop"]' and make the expression
60 * var.
prop are only suggested names for example case)
To add and bake a property, choose the object you are going to bake on, open the "Custom Properties" Panel, add a property, key in a number, make it a float type (eg 0.0) and then add a keyframe. Select and Bake to Sound from the graph editor as you would any other property.
You can see the datapath on the active fcurve properties panel N used for the datapath of the driver variable, or use the copy data path on mouse menu of the custom property field, and paste into the datapath field of the driver variable.
Go one level further and add another custom property and use it in the driver as the multiplier, then you can change the amplitude of the baked fcurve effect directly from a slider in the UI.
To make it easier I have put together an addon, Sound Drivers.
