Friday Math Movie – The Math in MP3 Audio Files
[12 Sep 2008]
This week’s movie gives us an overview of analog and digital music recording.
The recording engineers in this movie are strongly anti-MP3, since a lot of the subtlety of the original is lost.
There are some people who strongly hold on to the belief that LP (long play 12″ black vinyl discs) analog recordings are better than digital recordings.
Maybe, but remembering the inconvenience and the terrible sound of scratched and dusty LPs, I’m not going back to LP records any time soon…
