Description

Summary of the bug:
ffmpeg contains ape decoder which can not properly handle 24bit
How to reproduce:

latest Monkey audio cli 5.55

MAC.exe cut.wav cut.ape -c5000

MAC.exe cut.ape cut_mac.wav -d

ffmpeg.exe -i cut.ape -c:a pcm_s24le cut_ffmpeg.wav

cut_mac.wav - equals to source cut.wav
cut_ffmpeg.wav - contains garbage
