Capitol's recording studios were designed to minimize noise and vibration, then newly important goals in the high-fidelity sound era. An inner wall floating on layers of rubber and cork was erected inside the building's {{convert|10|in|mm|adj=mid|-thick}} concrete exterior walls, leaving a one-inch air gap to provide complete sound isolation.<ref>{{cite news|title=Capitol fears for its sonic signature|url=http://www.latimes.com/entertainment/news/la-me-capitol18-2008jun18,0,2972316.story|access-date=April 18, 2013|newspaper=[[Los Angeles Times]]|date=June 18, 2008|first=Bob|last=Pool}}</ref> The facility also features subterranean echo chambers that allow engineers to add reverberation during the recording process. Eight [[trapezoid]]al chambers are located {{convert|30|ft}} underground, with 10-inch concrete walls and {{convert|12|in|mm|adj=mid|-thick}} concrete ceilings. Speakers on one side and microphones on the other permit an echo effect of up to five seconds. Studios A and B can be combined for the recording of orchestral music and symphonic film soundtracks. The first album recorded in the tower was ''[[Frank Sinatra Conducts Tone Poems of Color]]''.
