Audacity noise reduction
For example, the FFT Size in OcenAudio adjusts how fine-grained the noise profiler is (bigger number equals better quality). In OcenAudio, select the noise, go to Effects > Noise Reduction, and click Get Profile under Noise Profiler.įinally, you can go ahead and adjust any settings available. In FL Studio’s Edison, select the noise and RIGHT-click the toothbrush icon. So, select a part of the audio where there is only noise (no voice/instrument), then click on “Get Noise Profile” or something very similar. However, almost all software uses similar terminologies, so you should be able to follow the steps reasonably easily.įor the denoiser to work, it needs to “listen” to the noise and create a noise profile. Since we cannot focus on every audio editor, we will use FL Studio and OcenAudio alone. The following audio editors provide this feature: Do an online search for “noise reduction your_audio_editor” and see if you can find a mention of “noise profiles,” “noise reduction,” or “denoiser” feature anywhere. Make sure your audio editing software supports noise reduction. For example, neither FL Studio nor OcenAudio can provide you the level of flexibility that much more expensive software like Izotope RX-8 does. A point worth noting is that some software products are better at noise reduction than others. So, you’re better off limiting its usage over short parts of the audio. Unfortunately, an extreme amount of noise reduction will introduce artifacts in your audio. Therefore, it is the most universally effective method on our list. So, this method uses an automated process called Noise Reduction, which can remove even the noise over your vocals/instruments.
When the noise is complex and spread throughout the frequency spectrum, you cannot isolate it using a simple EQ. Doing so avoids artifacts over the rest of the frequency spectrum. Adjusting the Q factor or, in OcenAudio’s case, the Passband limits will allow you to narrow down the filter precisely over the hum only. A notch filter in FL EQ 2.Ī bandstop/notch filter over the hum in OcenAudio.Ĭonfirm what you are removing is the hum alone. You can also use a peak filter to reduce the gain if you aren’t looking for an extreme result. Add an EQ band over the peaking frequency (95 Hz in our example), and set its shape to a notch filter. You can do so only when the frequency doesn’t overlap with your voice/instrument. The easiest way to get rid of such a humming is to EQ it out.
The peaking (tall) part is the hum so, note that the frequency (labeled at the bottom of the graphs below) is close to 100 Hz. Simply playback the recorded audio looping over an empty part where you aren’t speaking/playing, and note the analyzer. Use a frequency analyzer (some EQs have built-in analyzers) to identify the problematic frequency. We will be using FL Studio and OcenAudio for demonstration. Hence, we will be using an EQ to remove parts of the frequency spectrum affected by the noise. This method focuses on humming that is generally not affecting your audio. So, we will provide a free and paid alternative. Most methods have more than one way to achieve the effect.
