If the speaker is too far from the mic, you’ll need to boost the mic’s sensitivity, which, as a consequence, boosts noise levels as well. The pros in the podcasting business describe a recording done with the speaker talking right into the mic as one with a “high speech-to-noise ratio.” To achieve this ratio for your own podcasts, place podcast mics near each speaker’s mouth - ideally about a palm’s length away. Here are six ways to use your audio hardware and sound recording skills to produce noise-free audio: Noise cancellation software can help you in post-production, but nothing beats a clean, noise-free recording to start with. The best way to get rid of background noise is to block it out during the recording process. How to get rid of unwanted background noise when recording Examples include rain, wind, thunder, traffic, and ambient conversations - sounds that come and go depending on the recording environment. True to its name, irregular noise occurs on an irregular basis. These include plosives from consonant sounds like “p” and the loud crackle that happens when you plug in an audio cable. Audio engineers group the clicks and pops you hear on certain audio recordings into a broad category called impulse noise. You can often trace narrowband noise to a poorly grounded mic cable or an instrument’s pickups. Electrical circuits can cause narrowband noise that creates a hum in your audio recordings. Compared to broadband noise, narrowband noise occurs over a much smaller range of frequencies. When these frequencies produce noise all at once, it creates the familiar hissing and buzzing sound commonly known as background noise. Broadband noise occurs over a wide range of frequencies. To learn how to get rid of background noise on mics, it helps to know the four main types of noise that can diminish the sound quality of your recordings:
