This post describes how to get rid of background noise on a condenser mic, such as the one used in smartphones, and how to improve audio quality. Background noise is often introduced into recordings through environmental noise, such as wind or traffic, or from the user’s own speech. It can also come from other audio sources, such as keyboards or other equipment.
Background noise in your recording makes your voice sound muffled and unprofessional. Noise reduction is a process that removes this unwanted noise. It is a great way to improve the quality of your audio recordings. It will make your voice sound clearer and more professional. It will also make your voice sound more natural.
Although condenser microphones are designed for recording in situations where the ambient noise is too high for a dynamic microphone. But the diaphragm of a condenser mic is very sensitive that sometimes it picks up sound waves from the air. These distortions can be eliminated in the following ways;
1. Low-Pass Filters
The most common way to reduce noise is to apply a low-pass filter. This is a type of digital signal processing (DSP) that is used to remove unwanted sounds from a recording.
2. Compressors and De-essers
Another way is to use a compressor, which is a device that reduces the level of loud sounds. You can also use a de-esser, which is a type of compressor that removes the unwanted high frequencies. However, a compressor is better because it can remove more noise. The next step is to equalize your microphone. Equalizing your microphone will make it easier to hear your voice. You should do this by turning the microphone’s gain down until you can hear your voice clearly.
3. Windscreens, Pop Filters, and Windsocks
The most common way to reduce this unwanted background noise is to use a windscreen, a pop filter, or a windsock.
- The windscreen is a piece of foam or a cloth that is placed over the microphone and reduces wind noise.
- The pop filter is a small piece of foam or cloth that is placed between the microphone and the windscreen. You can either buy a pre-installed pop filter or you can put a piece of paper over the mic.
- The windsock is a small piece of cloth that is placed around the microphone to keep it from being blown away by the wind. Both windscreens and pop filters can be used in conjunction with a windsock.
4. Volume buttons on the Computer
You can use the following techniques if your mic is connected to the computer.
Firstly, turn off the microphone. You should do this before you start recording. You can do this by pressing the button on the microphone or by turning the volume down on your computer. This way, you can avoid unwanted background noise from coming into your recording.
5. Volume Levels on the Microphones
The first thing to do is to check the volume levels on the microphone. Make sure that the levels are set correctly. If they aren’t, then you may have to increase the volume of the recording. Therefore you should adjust the microphone to a lower volume. This will reduce the amount of ambient noise and will help to remove the noise from the mic.
6. External Mic or Preamp
You can also use an external mic preamp or a mixer that has an attenuation control to do the same thing. While, if you are using a condenser mic with a built-in preamp, then try to turn it down a little.
7. Frequency Range of Condenser Mic
Try to use a condenser microphone that has a wider frequency range. And turn off the lights and turn down the light level in your recording studio.
In conclusion, The noise reduction process is not a difficult one. In fact, it’s quite simple. It’s just a matter of finding the right settings to suit your particular needs. But, it’s important to keep in mind that the settings you use will have a big impact on the overall quality of your recordings. For example, the gain setting will have a major impact on the volume of your audio signal. If you set it too high, you’ll lose a lot of the low-level information that’s contained in your audio signal. This will make the audio recording sound like a muddy mess. On the other hand, if you set the gain settings too low, you’ll be losing the high-frequency information that’s contained in your audio signal. This will make your audio recording sound flat and lifeless. In addition, you’ll also lose the clarity of your audio recording. So, you need to balance the volume level with the frequency content of your audio recording.
