Audio clip with an envelope

 

In the image above, the volume of the sound now goes from 100% up to about 170% and then slowly down to 100% again.  In this manner, you can add as many points as you'd like to shape the volume of the sound over time.

 

hmtoggle_arrow1 Keyboard Modifiers

 

Add Points: Hold the CTRL key down and to add points anywhere on the sound.

 

Move Line: Hold the SHIFT key down and click down on an envelope line to move the line up or down.

 

Delete Points: Hold the ALT key down and click points to remove or delete them.

 

hmtoggle_arrow1 Setting Exact Value

 

If the desired level cannot be set via mouse dragging, you can set it by right clicking on the point and choosing "Edit Exact Value..."  This brings up a dialog box that lets you set the exact value.

 

hmtoggle_arrow1 Fades, Boosts and Reductions

 

These are shortcuts that add multiple envelope points at a time.  Select an area of a sound and choose one of the following predefined options.

 

"Sound" menu > Envelopes > Fade In

> Fade Out

> Reduce

> Boost

 

Fades go from one volume to another over time.  Boost increases the volume for a selected period of time.  Reductions lower the volume for a selected period of time.

 

hmtoggle_arrow1 Clip Volume

 

Volume can be set to values from 0% to 200% ( -Inf dB to +6 dB ).

 

hmtoggle_arrow1 Clip Pan

 

Pan is the volume balance between the left and right channel (speaker).  You can pan a sound so that it sounds like it is moving from the left to right or vice-versa.  This is what makes stereo more interesting to listen to.

 

Pan can be set to values from 100% left to 100% right.
