I see I lose data on the [18kHz..) range, but at the same time as a male I'm not supposed to hear that past in my early 30s, sprinkle concerts on top and make it more like 16kHz :/

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
    ```
