How to adjust volume for sections of a track?

I'm looking to be able to highlight a section of a track and adjust the volume levels up or down without affecting the rest of the track's levels. Has anyone done this and can you share the method with me? Thank you.

Split the item where you want to make the volume change and raise the volume handle on the split piece. If its a VSTi track with no items, you'll need to use automation.

another, often more detailed method is with envelopes.... it can be more 'detailed' as you can either have the changes very abrupt or gradual to whatever degree you wish... this is done by chooing the shape of the points on the volume envelope. You can look this up in the user's guide as well. There are two types of Vol. envelopes... one is called Pre FX If you use that you will actually see the wav form change shape with your env. adjustments. To get you started.... on the Track panel, clk the env. button near the fx button... in the next dialog check Vol or Vol Pre fx and also check the visible box... If you want abrupt changes use a square shape for the points... if you want gradual, try the linear shape... If you like, you can make a time selection of the part of the wav you want to change volume for, and then just move the slider on the vol. env. panel... in this way it will increase or decrease the vol. for just the part in the time selection. If you screw up at first, just delete [clear] that envelope lane and start again from fresh... I like envelopes as they involve no spliting of the wav file.

Wow. Great responses and thanks for posting them so fast. Awesome that you would post an animated demonstration! I've got it to work using the Pre-FX Volume sliders, but I would like to have a more gradual volume decrease. Could you explain in more detail about the "square points" and the "linear shapes." Assume I'm retarded. Haha. Thank you.
