However, it is a topic worthy of consideration, especially when working in home studios.Д®very device connected to the power grid in your area causes distortions in the electricity you use. This type of noise is widely unknown, misunderstood or simply disregarded. Electrical Line Noise Electrical Line Noise: Finally, tracking late at night may result in less ambient noise from outdoors and a quieter power grid. Water running through interior plumbing can be surprisingly loud and should also be considered. Some would argue that using a high-pass filter in tracking can remove important low harmonics from the source but in my opinion, something like an 80 Hz high-pass filter does not pose a problem for any source except kick drum or bass guitar.Д«eyond the more obvious tips of silencing mobile phones, I also suggest temporarily disabling climate-control units and other appliances with motors for the duration of tracking. A high-pass filter on a mic or preamp can remove a lot of unnecessary noise from your recordings and help prevent A/D clipping. Even if the A/D converters in your audio interface do not clip as a result, the tone or dynamics of the source may be altered. If a vehicle passes by or someone in another part of the building slams a door, some mics will pick up the low-frequency transients and rumbles with ease. High-pass filters can also be very useful in tracking.

Attaching a microphone to a portable reflection filter of good quality can also be very effective in absorbing and diffusing room reflections that can obscure the direct sound from the source. I also encourage my clients to either procure commercially produced acoustic treatments or fabricate their own. In terms of tracking, the influence of room acoustics on recordings may be reduced with careful mic placement and consideration of signal-to-noise ratio. You will then have a solid baseline to work from. Of course, you should also do everything within your means to acoustically isolate your listening environment from other rooms in the same building and from the world outside. First, get the best D/A converter or interface and monitors you can get (sized appropriately for your room), then do everything within your means to control acoustic reflections and resonances in that environment. In short, if you cannot really hear what is going on, you will miss problems that are likely to be magnified and impossible to isolate in later stages of production. While some solutions are expensive, patience, creativity, and determination can lead home studio owners to effective solutions.

This type of noise can take many forms and is one of the most difficult to mitigate.
