Hey there! As a microphone supplier, I've been getting a lot of questions lately about microphone de - essers. So, I thought I'd take the time to write this blog and explain what a microphone de - esser is, how it works, and why it's important for your audio setup.
Let's start with the basics. What exactly is a microphone de - esser? Well, a de - esser is a type of audio processor that's designed to reduce or eliminate the harsh "s" and "sh" sounds in your recordings. These sounds, known as sibilance, can be really annoying and distracting in audio, especially in vocals. You know how sometimes when someone says words like "snake" or "ship," the "s" or "sh" sound can be so sharp that it almost hurts your ears? That's sibilance, and a de - esser helps to smooth that out.
How does it work? A de - esser analyzes the audio signal and specifically targets the frequencies where sibilance occurs. Usually, sibilance happens in the high - frequency range, around 5kHz to 10kHz. When the de - esser detects these sibilant frequencies, it automatically reduces their volume. It's like having a little audio wizard that listens for those annoying "s" and "sh" sounds and tames them for you.
Now, you might be wondering why you even need a de - esser. Well, there are a few good reasons. First of all, if you're recording vocals, sibilance can make the recording sound unprofessional. It can be hard to listen to, and it can also make it difficult to understand what the singer is saying. By using a de - esser, you can make your vocal recordings sound much cleaner and more polished.
Another reason is for podcasts or voice - over work. In these types of recordings, clear and crisp audio is essential. Sibilance can be a real deal - breaker, especially if your listeners are using headphones. A de - esser can help ensure that your voice comes through clearly and that your audience can focus on what you're saying, rather than being distracted by those harsh "s" sounds.
If you're into gaming and using a microphone for online gaming, a de - esser can also be super useful. When you're yelling and talking excitedly during a game, it's easy to produce a lot of sibilance. Using a de - esser can make your voice sound better to your teammates, and it can also prevent any audio issues that might come from those sharp high - frequency sounds.

There are different types of de - essers available. Some are built - in to microphones themselves. For example, some high - end microphones come with a built - in de - esser feature. This can be really convenient because you don't have to add any extra equipment to your setup. Just plug in your microphone, and you're good to go.
Other de - essers are external units. These are separate devices that you connect between your microphone and your audio interface or mixer. External de - essers often offer more control and flexibility. You can adjust the threshold (the level at which the de - esser starts working), the ratio (how much it reduces the sibilant frequencies), and other parameters to get the perfect sound.
When choosing a de - esser, there are a few things to keep in mind. First, consider the quality of the de - esser. You want one that can accurately detect sibilance without affecting the rest of the audio too much. A good de - esser should be able to reduce sibilance while still maintaining the natural sound of the voice or instrument.
Also, think about the ease of use. If you're new to audio recording, you might want a de - esser that's simple to operate. Look for one with intuitive controls and clear indicators.
Now, let's talk about how to use a de - esser effectively. The first step is to set the threshold. This is the level at which the de - esser starts to work. You want to set it high enough so that it only kicks in when there's actual sibilance, but not so high that it misses some of the sibilant sounds. Start by setting the threshold a bit high and then gradually lower it while listening to your audio. You'll start to hear the de - esser reducing the sibilance as you lower the threshold.
Next, adjust the ratio. The ratio determines how much the de - esser reduces the sibilant frequencies. A higher ratio will reduce the sibilance more, but it can also make the audio sound a bit unnatural if it's set too high. Start with a moderate ratio, like 2:1 or 3:1, and then adjust it based on the sound you're going for.
Some de - essers also have a frequency control. This allows you to specify the exact frequencies where the de - esser will work. You can use an equalizer or a spectrum analyzer to identify the frequencies where the sibilance is most prominent and then set the de - esser to target those frequencies.
