Fade In/Fade Out using Envelope?

[huckfinn]

I used Wavepad regularly in distant past,  switched to AVS4You's audio editor about 5 years ago.   I just gave the newest wavepad a spin, and am quite impressed with layout, waveform display, many other things.
I'm used to dBs, not percents, so added presets to the amplification.   Fine, although wish I could reorder them.

My one concern is lack of flexibility with fade/in - fade out.    Wavepad only has what seems to be a linear fade;  I want the sound to decrease quickly at first then fade slowly (this is called "fade slowly" in avs4you.)     I suppose something like this could be done by defining an envelope and applying,  but that would be tedious, and I imagine different envelopes might be needed for different fade durations.

I'm very surprised that wavepad doesn't offer different types of fade in/out, it's such an essential feature of music editing.  The fade they offer is quite poor in my opinion.

Are there work arounds?  Thanks.

After some more experimenting, the envelope function works quite well for designing fade outs.

I was concerned that the curve wouldn't be smooth enough, or need to be redesigned for different durations, but the windowing is fine.
