 filtering it first, resulting in aliasing artifacts. You get aliasing artifacts when
 there is high-frequency audio in the input audio that falls above the nyquist frequency
 of the chosen target sample rate. Audio with frequencies above the nyquist frequency
-cannot be reproduced accurately and get "reflected"/mirrored to other frequencies.
+cannot be reproduced accurately and get "reflected"/mirrored to other frequencies. The
+aliasing artifacts "replace" the original high frequency signals. The result can be
+described as coarse and metallic.
 
 After the downsampling, the signal gets upsampled to the original signal again, so the
 length of the output becomes the same as the length of the input.

However, both methods lead to aliasing artifacts.
