Emma Smith of WhispersRedASMR said she started off with a simple camcorder for both sound and video, but then added a Zoom H4N, which cost around $200, to record sound separately. This is a microphone that is commonly used in music, film, and podcasting.
Now, Smith records in stereo, which means she uses two or more microphones at a time. She might use a microphone on her lapel as well as several others "dotted around the room," she said.
She also uses lighting and a Panasonic GF6, a 16-megapixel camera that retails for $330 and up.
Tony also uses a Zoom H4N microphone, as well as a Blue Microphones Spark microphone ($200) and is an "enthusiast" of the 3Dio brand ($500 to $2,000). 3Dio microphones are binaural, meaning it attempts to capture sounds exactly the way humans perceive them.
The prices may be intimidating, but Smith said beginners needn't shell out their savings. "Just use whatever equipment you can afford," Smith told Business Insider.
ASMR Academy recommends the Yeti Microphone ($129) as a microphone for beginners.
Emma Smith, or WhispersRed, said if you're especially interested in presentation or graphic design, that can also be incorporated into your videos — sound and visuals work in harmony.
