** [[Music]] has a widely varying crest factor.  Typical values for a processed mix are around 4–8 (which corresponds to {{nowrap|12–18 dB}} of headroom, usually involving [[audio level compression]]), and 8–10 for an unprocessed recording {{nowrap|(18–20 dB).}}<ref>[http://www.aes.org/par/c/#cps Crest factor definition]  — [[Audio Engineering Society|AES]] Pro Audio Reference</ref><ref>{{Cite web |url=http://www.digido.com/level-practices-part-1.html |title=Level Practices in Digital Audio |access-date=2009-10-11 |archive-url=https://web.archive.org/web/20090618130742/http://www.digido.com/level-practices-part-1.html |archive-date=2009-06-18 |url-status=dead }}</ref><ref>[http://www.mackie.com/pdf/CMRefGuide/Tips_Ch4.pdf#page=2 Gain Structure — Setting the System Levels] {{Webarchive|url=https://web.archive.org/web/20070928044203/http://www.mackie.com/pdf/CMRefGuide/Tips_Ch4.pdf#page=2 |date=2007-09-28 }}, [[Mackie (company)|Mackie]] Mixer Tips</ref><ref>[http://digitalcontentproducer.com/mag/avinstall_setting_sound_system/index.html Setting sound system level controls: The most expensive system set up wrong never performs as well as an inexpensive system set up correctly.]</ref>
