Noisy Preamps
Another potential issue with USB microphones is their preamps. The preamp is the circuit that amplifies the audio signal before it’s converted to digital. Many USB microphones have preamps that are noisy and can introduce hiss and hum into the signal. This can be particularly problematic when recording vocals, as it can make the sound seem cheap and amateurish.
Preamp Noise Comparison
| Microphone | Preamp Noise |
| — | — |
| Blue Yeti (USB) | 10 dB-A |
| Rode NT-USB (USB) | 4 dB-A |
| Focusrite Scarlett (XLR) | -128 dB-A |
As you can see, the Blue Yeti has a relatively high preamp noise level, while the Rode NT-USB has a lower noise level. The Focusrite Scarlett, an XLR audio interface, has a much lower noise level, which is typical of high-end audio interfaces.
Can USB Microphones Be Used for Recording Vocals?
While USB microphones may have some limitations, they can still be used for recording vocals. In fact, many musicians and producers have used USB microphones to capture high-quality vocals. The key is to choose a USB microphone that’s designed for music recording, rather than podcasting or speech.
What to Look for in a USB Microphone for Vocals
