Sampling does not lose information below the Nyquist limit, but quantization does introduce errors that can't be fixed. And resampling at a different rate might introduce extra errors, like when you recompress a JPEG.
At least I don't have tinnitus.
Here's my test,
```fish
set -l sample ~/Music/your_sample_song.flac # NOTE: Maybe clip a 30s sample beforehand
set -l borked /tmp/borked.flac # WARN: Will get overwritten (but more likely won't exist yet)
cp -f $sample $borked
for i in (seq 10)
echo "$i: Resampling to 44.1kHz..."
ffmpeg -i $borked -ar 44100 -y $borked.tmp.flac 2>/dev/null
mv $borked.tmp.flac $borked
echo "$i: Resampling to 48kHz..."
ffmpeg -i /tmp/borked.flac -ar 48000 -y $borked.tmp.flac 2>/dev/null
mv $borked.tmp.flac $borked
end
echo "Playing original $sample"
ffplay -nodisp -autoexit $sample 2>/dev/null
echo "Playing borked file $borked"
ffplay -nodisp -autoexit $borked 2>/dev/null
echo "Diffing..."
set -l spec_config 's=2048x1024:start=0:stop=22000:scale=log:legend=1'
ffmpeg -i $sample -lavfi showspectrumpic=$spec_config /tmp/sample.png -y 2>/dev/null
ffmpeg -i $borked -lavfi showspectrumpic=$spec_config /tmp/borked.png -y 2>/dev/null
echo "Spectrograms,"
ls -l /tmp/*.spec.png
```I wish I understood this better and at least knew whether it's true or false. I have to do more reading on it.
