Twenty Thousand Hertz Explores the History & Technology of Shure's SM7, Your Favorite Podcast's Favorite Microphone
|
Like many of the world's most popular podcasts, Twenty Thousand Hertz records every episode with the exact same microphone: Shure's SM7. Host and general audio authority Dallas Taylor calls it the most prolific and important mic of the last two decades, with timeless technology that dates back to the 1950s. On today's edition of Twenty Thousand Hertz, the show about the world's most recognizable and interesting sounds partners with Shure to examine the device that captures the human voice so beautifully. Featuring interviews with official Shure historian Michael Pettersen and Senior Product Manager John Born, Dallas Taylor explores 80 years of sonic innovation to reveal not only the SM7's revolutionary design, but the sales spike that turned it into a staple of professional studios, bedroom streaming rigs and beyond.
Before Joe Rogan, My Favorite Murder, Twenty Thousand Hertz, WTF and more began recording with the SM7, singers like Mick Jagger, Red Hot Chili Peppers' Anthony Kiedis and Sheryl Crow used it to track vocals. Michael Jackson gave the microphone much-deserved attention when he wielded it for every song on Thriller, but the SM7 still remained far less popular than Shure's other iconic models. The company was founded in 1925 by 23-year-old S.N. Shure, and by 1932 they were manufacturing their own microphones. Then, thanks to visionary inventor Ben Bauer, they changed the way sound was recorded forever. The first Shure Unidyne Microphone was popularized by Elvis, and in the late '50s the Unidyne Three capsule helped make modern rock concerts possible. Developed by Bauer's successor, Ernie Steeler, The Beatles used it on their US tours, and the same capsule still appears in Shure's unmistakable SM58 and SM57.
The Unidyne Three capsule also sits inside of the SM7, which was originally developed as an option for voiceover work. Because the SM7 is a dynamic microphone - not a ribbon or condenser - it's able to isolate the desired source from the sounds of one's environment. The SM7 also emphasizes audio frequencies in the sibilance range of a human voice, making speech easier to understand. Dallas Taylor demonstrates the versatility of the SM7 through the two frequency response switches that the mic offers. Although some radio stations, engineers and select musicians caught on after its release in 1972, the SM7 largely idled for 35 years, until podcasters discovered its magic. Since finally taking off in 2007-2008, and then surging again with video game streamers in 2014-2015, the SM7 has done more business than Shure could have ever imagined.
