Is your audio recorder adding noise (hiss) you can’t hear until it’s too late? Learn why Equivalent Input Noise (EIN) is the hidden spec that makes the difference between clean, professional audio and that annoying hiss underneath your voice. Whether you’re a podcaster, YouTuber or musician, understanding EIN will help you pick the right audio recorder or if you have a noisy recorder already with a high EIN, you can fix it.
Many popular recorders and preamps claim “low-noise,” but what does that actually mean? Hear real-world EIN examples, compare the Zoom H4n vs MixPre-3, and help you figure out why some recorders make your mic sound clean while others add unwanted noise — especially if you’re using dynamic microphones like the popular SM7B.
