Audition effects "volume"

[adam5411]

Hi, I wanna add some effects in adobe audition and it works for the selected area, but how can I make this effect "growing up" in the start, slowly ending at the end of the selected area. I wanna make  it more "smooth" when effect is coming up, and when its going down

To precise it more, I dont wanna have that aggresive transition between selected section (where i put effect) and rest of the song:

What effect are you trying to apply to the audio? Some kinds of volume level effects can have a fade in and out. Others may not. So we need to know what you are trying to do and how long the transition needs to be before being able to give a definitive answer.

There's several ways you can do this. 

If it was me, I'd work in Multtrack mode and use volume envelopes to track along with the effect setting in and ending.  I'd probably just do it by ear to get the change I'd want.

Or, also in Mutitrack you can use an Automation Lane to directly control the amount of effect.  To get an automation lane, go to the bottom box in the editing panel at the left end of the track (you may have to make the track wider to see it).  Find a box at the bottom, probably saying "Read" when you get there.  Click the little arrow to the left of the box and you'll be offered the option of "Show Envelopes".  You'll probably want "Rack input" and then you use keyframes to control how much effect you start with and end with--you can taper it as you like.

Thanks a lot.

SS for someone who is looking for it too.

Another way to deal with such effects, again using the Multitrack view, is to process the whole audio track with the effect that you require in Waveform view and save the file with a new name. then you can add the 'effected' audio file on another track in the Multitrack view and cross fade between them as and when you want.

Indeed. Before the days of automation lanes that's exactly how I did it.  I have one theatre track that starts 100% dry and gradually goes to heavy reverb at the end.  The volume enveopes were both diagonal straight lines.

(Thanks to ryclark for point out this was originally in the wrong thread.  I should never post answers from my phone!)
