When it comes to recording audio, most of every mic sound muffled. This is due to different frequencies canceling each other out. There are a few reasons as to why this may occur.
In this blog post, we’ll be discussing the most common reasons why does my mic sound muffled and what you can do to fix it.
Why Does My Mic Sound Muffled
1. Poor Room Acoustics
The environment that you record in definitely affects the result. For example, if you’re recording somewhere full of hard reflective surfaces (tile, glass), your voice will tend to bounce around and create an echo effect.
The same goes for if you’re recorded in a room with lots of space. There’s nothing to absorb the sound, and it will just echo around. This can be a particular issue with podcasting, as people often record in their home offices or living rooms.
The best way to counteract this is to find a room with some acoustic treatment. This could be anything from acoustic foam panels on the walls to rugs on the floor.
2. Wrong Mic Placement
Where you place your mic can also significantly impact the sound quality. If it’s too close to the source, it will pick up all the breathing and mouth noise. A bit further away will make it sound like it’s far away or muffled.
The best place to place the mic is usually between these two extremes. Slightly off-axis from your mouth works best, as it won’t pick up any of your breathing sounds, but you’ll still be able to keep some decent level of proximity effect.
3. Breathing Into The Mic
If you are breathing directly into the front of the mic, it will pick up all that breathy sound and make your vocals sound muffled or distorted.
The best thing to do is to angle the mic upwards slightly so that your breath goes over the top of it or to the side.
4. Mic Position and Angled Recording
The mic should be at roughly the same height as your mouth when you’re speaking into it, which is usually just below chin level for most people. If you have a desk in front of you higher up than this, you won’t get a consistent sound, as it will be different for when you’re in front of the desk compared to when you’re in front of your computer.
Mic Angles are something that most people don’t think about, but one small change is all it takes to change the sound completely. For example, if your mic is set on a desk pointing directly ahead, then it’s going to sound very different if you have it positioned so that it’s pointing upwards towards your mouth.
Try changing the mic’s angle sometimes and see how this affects the sound. For example, if you’re using a condenser mic, aim to get around 45-degree angles at both ends of the spectrum (pointing up to 45 degrees away from the axis and pointing directly at 45 degrees).
5. Mic Cable
One of the most common causes for muffled sounding microphones is the cable you’re using to connect it to your recording device. If your cable isn’t shielded well enough, then it will act as an antenna and pick up all kinds of interference from other things in the area. The resulting sound will be a low-frequency hum and noise.
Try using a different piece of equipment, or use better shielding to see if it helps. Of course, it’s also always worth checking that the cable is plugged in correctly!
6. Pop Shield
If you are getting loud popping sound on your recordings when you speak certain words, this may signify a lousy pop filter. A pop shield is a piece of equipment placed between the mic and your mouth to help stop loud popping sounds from occurring when certain words are spoken.
One trick you can do if you don’t have access to any filters is to hold your hand closer to your face when speaking these words (make sure you keep your hand out of the shot when filming).
7. Poor Quality Mic
Sometimes, the sound quality isn’t as good as it could be because you’re using a low-quality microphone. This can be due to several factors such as the build quality, the materials used, or even the way it’s been manufactured.
If you’re finding that your recordings don’t sound as good as they should be, then it might be time to upgrade to a better quality mic. There are a lot of different mics on the market to choose from, so take your time and do some research to find the best one for your needs.
8. Wrong Settings on the Device
A lot of people don’t realize that even if you have a great mic, it can still sound terrible if the settings on your recording device are wrong. This includes the levels, the tone, and even the noise floor.
It’s essential to spend some time playing around with the different settings to find what works best for you and ensure that your microphone is recording correctly. A good rule of thumb is to aim for an input level on the device of around -12dB for a condenser mic and around -18dB for a dynamic mic.
How to fix the Mic Sound Muffled
- Move the mic closer to your mouth
- Angle the mic away from your mouth
- Use a shielded cable for the microphone
- Try changing the angle of the mic (45 degrees angled)
- Make sure the pop shield is plugged in correctly and working well
- Investigate better quality microphones
- Adjust the settings on your recording device
- Use a noise gate to clean up your recordings
- Investigate software that can improve the sound quality of your recordings (such as Audacity)
- Make sure you’re speaking into the mic at the correct distance (1-3 inches away)
These are just some of the things that you can do to help improve the sound quality of your microphone. If you’re still having trouble getting the sound you want, don’t be afraid to ask for help.
There are many different people out there who can give you advice on how to improve your microphone sounds.
