[LMMS-devel] AFP sampling

[DeRobyJ <de...@gm...>]

With AudioFileProcessor the user is able to re-use old ogg/wav files in 
their new compositions, but there is one little problem: clip.

If the user doesn't want to use the whole file, but a small part, he is 
able to do that, but it will mostly result in two clips: one at the 
start and one at the end. This is because the selection doesn't start 
from or end in a 0amp point of the wavegraph.

What the user should do now, it taking the file to audacity, make a good 
selection of the file and tweak it with a little fade-in/out if 
left-right channels are not in sync.

Would it be possible to create three new little buttons (one for each 
selection knob) in AFP that does this actions?
- Find a point "near" to the selection point which has the lowest 
amplitude, mathematically: min{ abs(leftAmpl) + abs(rightAmpl) }
        the program should decide what is "near" accordingly with the 
total selection length (I think "length/25" should be fine)

- If in that point total ampl is not 0, do a little fade-in (for start 
point and loop point) or fade-out (for end point)

It's crucial to have undo functionality, since the result may not be 
optimal, especially for short selections.
