Andy Moorer is the man behind “Deep Note,” the THX noise you are deafened with just as the THX logo pops up before a movie begins. The blog Music Thing featured an interview with him in 2005, which explains how the sound was made and notes that the score is a C program containing about 20,000 lines of code. There are many other fascinating tidbits about Deep Note, including this student’s attempt to recreate it.
