Pop Filters - What are they?

Sibilance is the bright burst of noise radiated by consonants such as "s," "t" and "f." With certain voices and mics, sibilance can be overpowering. One method for reducing sibilance with directional mics is to keep the mic directly in front of the mouth, while rotating it off-axis slightly. This reduces the high-frequency pickup of most mics and can eliminate problem sibilance. Ten or twenty degrees is usually enough to do the trick, depending on mic design and pickup pattern.

The most effective means of suppressing popping noises from plosives like "p" and "b" is the fabric pop filter. Stretched over a circular frame, the pop filter mounts to the mic stand or boom arm. Foam filters, whether inside the mic or placed directly over it, are rarely as effective or as acoustically transparent. If you're using a vocal mic with a built-in pop filter, try removing the grill and foam filter and placing the mic behind a fabric pop filter instead.
How to use a Pop Filter:
1)      Position the pop filter close to, but not touching, the microphone. Some pop filters are designed to be fitted to a second stand that can be positioned between the vocalist and the microphone. Most, however, are designed to be fixed directly to the microphone stand using a clamp or bracket. If adding the pop filter to a microphone stand, securely fix the bracket to the stand and then mount the pop filter.
2)      Angle the microphone and pop filter to the 10 o'clock or 2 o'clock position. This will further help to prevent plosive sounds.
3)      Record vocals as normal. The pop filter should not need to be touched or adjusted in any way during the recording after its initial setup.
4)      Remove the pop filter after use and wipe it down with a soft cloth. This will remove any moisture that has built up on the filter during the recording session.



*I highly recommend you buy one, and use it, you WILL Notice a difference in your vocals. My next post is on Mic Placement.
