Description

I noticed clipping in one of the songs that I downloaded with this tool. I compared it to the same track from another source, and there was no clipping there.
So I ran

ffmpeg -v error -i file.m4a -f null -
[alac @ 0x561315aa29c0] invalid element channel count

Interestingly, I have flac conversion enabled in the apple downloader config and the file was transcoded to flac without any errors, but the clipping is still present in the output.
Track in question - https://music.apple.com/us/song/carried-away-feat-night-lovell/1818471714
at around 28 second you can hear clipping.
There is no clipping when playing on apple music in the browser.
