So what does FIR mean? It stands for Finite Impulse Response. Reaper names its effect plugins by using "Rea" as a prefix (for Reaper), and then the name of the function after it. For more information on why I love Reaper so much, see my article, Why Reaper Rocks As A DAW.īut for some reason, Reaper doesn't have an effect called "Noise Reduction." So how do you reduce noise in Reaper? My favorite recording program, Reaper, is a digital audio workstation (DAW), which is a fancy way of saying full-featured multi-track recording program. Once it has the noise profile, it can do its thing. So you have to highlight a section of the recording where there is ONLY noise, and no voice, and feed that sample to the noise reduction tool.

In order to do this, the software has to know what noise looks like so it can separate it from the signal (voice). What noise reduction tools try to do is filter and removing as much noise as it can without also removing too much of the voice.

The typical method is to use an effect in an audio editor called "Noise Reduction." See my article How To Get Rid Of Background Noise In Audacity for how that normally works.īut since the noise and the voice are both together in the same recording, it isn't a perfect process. Recordings sound much better if you can reduce the noise, and that is what noise reduction tools are designed to do. The noise usually comes from a combination of stuff happening in the space/room where the recording takes place, and the electronics of the microphone and other gear involved. It is especially noticeable in recordings of just one thing, like a single voice. There is almost always a bit of background noise in recorded audio. I know! Who'd have thought to look for noise reduction editing chops under a moniker like that? Review of What Noise Reduction Doesįirst though, let's do a quick review of what noise reduction does for us in the world of recording.

It just happens to do it REALLY well, and non-destructively (if that's not a word already, I hereby create it). It would be similar to inverse filtering on the structure resonance.Īnother characteristic of the vehicle sounds are the doppler shifts at the time when the car is at closest distance to the microphone.The reason I didn't know about it sooner is primarily due to the fact that reducing recorded noise is not its only or primary function. You might also want to try to whiten the wind noise and see what happens. I read someplace once "Never invent gloves to fix a leaky valve" This is a situation where a little care in data collection saves a lot of trouble down the line. The mic structure gives color to the wind sound. One model is a random stream of impulses exciting a linear filter. The screen dampens the wind incident on the microphones structure and is a poor radiator. This is why a windscreen on microphone works.

Part of what you record is the broadband excited vibration of the microphone's full structure. If you stand near a steel tower in high wind, your will hear it "sing" You can often look at a tree in high wind and visually correlate the intensity of sound with the intensity of motion of leaves and limbs.

Some of what is heard, is radiation from monopoles (dipoles, and quadrupoles) within the flow and some are resonances related to the object doing the disruption. Turbulence, which is usually excited by interaction that is, the disrupted flow by an interacting object. Laminar air flow doesn't produce much in the way of sound.
