[BUG] Crossfade produces weird buzz artifact with FLAC tracks

sylsau commented 3 years ago

Hello,

First and foremost, thank you for this amazing software. It's been my go-to music player for years now, and flawlessly so. I stumble upon a bug that I describe below.

Bug description

When 2 FLAC music tracks crossfade from the first to the second, it produces a weird buzz sound artifact.

To reproduce the bug

Set MPD's crossfade with ncmpcpp config with: mpd_crossfade_time = 3
Add 2 flac music tracks to the playlist
Scroll to the end of the song
Hear noise artifacts when it crossfades from first song to second

I tested this with both FLAC and MP3 files of the same songs. No problem with MP3 tracks.
