Feature Request: Crossfade Playback with Adjustable Duration

[TheoMNT1]

Hi,

First of all, thank you for this amazing app! The gapless playback feature is great, but I think it would be even better if Amperfy could support crossfade playback, similar to what Spotify offers.

With crossfade, the end of the current track smoothly fades into the beginning of the next one, creating a seamless listening experience, especially for playlists or parties.

It would be great if users could also choose the crossfade duration (e.g. from 1 up to 12 seconds), so everyone can adjust it to their preference.

Would it be possible to consider adding this feature in a future release?

Thanks a lot for your work on Amperfy!
