Add audio fade at cut

[webmastak]

It would be nice if there were buttons to fade out the sound.

Example:

I'm sorry but this is an operation that is not possible to do lossless. See #372

Why, then, everything works here mp3cut.net ?
And this is not even an application, but a web service running on Node.js + Vue.js

mp3cut.net is not a lossless editor. losslesscut may implement it in the future, when it gets lossy operations

According to this reply at HA forums:

The MP3 format can shift volume in 1.5 dB steps. One can achieve a coarse fading effect by successive 1.5 dB volume changes, and mp3directcut can do that.

mp3DirectCut FAQ claims:

How to fade in or out an MP3 in mp3DirectCut?
The easiest way is to use "Simple fade" or "Two-stage fade". Point to the position where a fade should end (fade in) or start (fade out). In the Edit menu choose a fade option. Adjust the fade by dragging the grey handle(s): Left button up/down for level, right button left/right for position. With fade curves you can create more complex fades. Each cue can be used for fading. A cue is created by pressing Cut on a zero-length selection (dotted line). Gain adjustment is only possible for MP3, not for AAC and MP2.

Hope that helps.

I think this is such a narrow use case (only mp3 files) that it's not something losslesscut will support. Maybe for this use case you can use https://mpesch3.de/ to fade/in out the clips, then after that is done, use losslesscut to merge them?
