PS4: Audio fading/crossfading?

[SoloTSi97]

I would like to cross-fade two audio clips.

I added the first song, then set the end marker so that the song stops at the desired point. I pressed the Fade-Out button and hit Okay.

I added the second song, pressed the Fade-In button and hit Okay.

I then played my slideshow. I can't say I'm hearing any noticeable fade out or fade in effect on either song. So, question #1 is ... how do I adjust the amount of fade in/out time? I suspect that I set the fade out and fade in incorrectly, and they are set to use a fade time that is much too low (i.e., they fade out over the course of like 0.1 seconds or something rather than the 3-5 seconds I want).

Question #2: The answer to question #1 will achieve the desired fade effect, but is it possible for PS4 to actually cross-fade the songs? Fade clip #1 out as clip #2 is fading in simultaneously?

Thanks in advance for any insight.
