Answer: Tom's Diner – Suzanne Vega
In the early '80s, the German doctoral student for electrical engineering Karlheinz Brandenburg worked on his Dissertation. His research has focused on digital audio coding and perception techniques ̵
To test the quality of the compression algorithms he made, he noted his focus on human vocals. Instrumental music compresses pretty well, but the human ear is set high to detect any irregularities in the human voice. Brandenburg was confident that any compression algorithm that could successfully compress the human voice without any problems would handle everything else well.
In order to test his algorithms, in 1987 he chose the a cappella version of the hit Toms Diner by Suzanne Vega, with his words: "I knew that it would be almost impossible, this warm A- He used her voice as a benchmark and refined the algorithms so they could not only compress the instrumental work, but also preserve the warmth of human vocals.
Following the intensive use of Tom's Diner by Tom's Diner for testing audio compression techniques, modern sound engineers designate the song informally as "The Mother of MP3." Bonus Trivia: Vega called it Tom's Diner, but it was inspired by the famous New York restaurant Tom's Restaurant, which was shown here near her birthplace in New York City.
