The Importance of Audio for Vlogging
Consider this: how long would you watch a YouTube video with poor audio quality? Probably not long, right? We’re quick to click away from videos where the sound is off because it’s frustrating and distracting.
On the other hand, if the visual quality is only average, viewers might still stick around if the audio is clear and engaging. Good audio can make up for less-than-perfect visuals, but poor sound is a deal-breaker. This makes audio arguably the most crucial element of your vlog.
Beyond just avoiding bad audio, improving your vlog’s sound can significantly boost viewer engagement. Remember, clear and professional audio not only keeps viewers hooked but also elevates the overall quality of your content, making it more enjoyable and shareable.
What’s needed for great video audio?
While using your camera’s built-in mic might seem easier and more budget-friendly, opting for an external microphone will significantly improve the quality of your audio. Here’s a guide to what you’ll need for capturing high-quality sound that complements your visuals:
- Microphones
When selecting a microphone for vlogging, consider your recording environment and style. For most vloggers, a lavalier mic is a great choice due to its hands-free convenience and ability to capture clear audio even when you're moving around. Omnidirectional lavalier mics are especially useful as they pick up sound from all directions, ensuring that your voice is recorded clearly regardless of how you move.
For instance, the NearStream AWM20T shines as a top pick for vlogging. This wireless lavalier mic delivers crisp, high-quality sound with its omnidirectional pickup. Its lightweight design ensures ease of use during active recording, while the One-Click Noise Canceling feature effortlessly cuts out background noise for pristine audio.
- Microphone Accessories
To complete your recording setup, consider adding a pop filter, boom arm, or mic stand. These accessories are essential for enhancing the quality of your microphone’s audio. A pop filter helps reduce unwanted plosive sounds, a boom arm provides flexible mic positioning, and a mic stand ensures stable placement for clear, consistent recordings.
- Headphones
Headphones play a crucial role in setting up your audio recording. They let you closely monitor your sound to ensure it’s clear and high quality. You don’t need to invest in high-end models, but comfort is key since you’ll be wearing them for extended periods. Options like the Sony MDR-7506 provides excellent sound quality and comfort during recording sessions.
- Software
When selecting software for recording your video and audio, focus on these key features:
- High Recording Quality: Choose software that supports at least 48kHz audio and 1080p video resolution for the best results.
- Multitrack Recording: Ensure the software can record each participant’s audio and video on separate tracks to simplify editing.
- Uncompressed Files: Opt for software that records in uncompressed formats to maintain high quality.
- User-Friendly Interface: Select software that enhances your workflow with intuitive features and a built-in editor to streamline post-production.

Tips for Recording Better Sound for Your Vlog
Capturing high-quality audio for your vlogs goes beyond just having the right equipment. To truly enhance your vlog’s audio, there are a few other key factors you need to consider as part of your overall audio enhancement method.
- Select the Ideal Recording Environment
If you’re not in a professional studio, optimizing your recording space is essential for great audio. Start by choosing a quiet room, avoiding spaces with echoes or a lot of background noise. Adding soft furnishings like carpets and curtains can help absorb sound and reduce reflections.
For even better results, consider basic soundproofing. Simple additions like foam panels or heavy curtains can significantly cut down on unwanted noise. Small adjustments, such as placing your microphone away from windows and closer to soft surfaces, can also improve the clarity of your recordings.
- Going Wireless
To achieve clear audio, it's essential to stay close to your microphone—ideally within two meters. While a camera-mounted mic works well for close-up shots in 'selfie' mode, it struggles with distance, making the audio sound distant and less clear. This is where wireless microphones prove invaluable.

Wireless mics, especially lavalier types like AWM20T, offer exceptional flexibility. They let you capture high-quality sound from up to 200 meters away. These small, discreet mics connect to a belt pack transmitter, which sends audio wirelessly to an on-camera receiver. For vloggers, the major advantage of using a wireless mic is the ability to maintain clear audio from a distance, ensuring that your voice remains crisp and clear even when the camera is set further back.
- Setting up Your Mic
Before you hit record, you’ve got to set yourself up for success by fine-tuning your audio levels and getting your mic placement just right.
Let’s start with gain. Gain is simply the boost your audio signal gets, measured in decibels (dB). To avoid distortion and get a clean recording, you’ll want to get your gain levels just right. Aiming for levels between -10dB and -20dB is a good start, but trust your ears more than the numbers—listen for what sounds best.

And don’t underestimate mic placement—it can make or break your recording. Ideally, you want your mic about 4 inches away from the sound source. Do a few test recordings, adjusting the distance until you hit the sweet spot. If you’re using a lavalier mic, make sure it’s pointing right at the speaker’s mouth, and watch out for any rustling from clothes.
- Keeping Audio in Sync
Syncing audio with video has evolved significantly over the years. In Hollywood’s early days, audio was recorded separately on tape and then matched to the video using clapperboards. These boards made a loud “clack” sound and displayed a visual cue of the boards clapping together, helping editors align audio and video.
Today, syncing is much more precise. We now use frame-by-frame editing to align audio and video at the sample level. For your audio project, ensure your settings are correct: use a sample rate of at least 48 kHz (or 96 kHz for higher quality) and match the frame rate (fps) to your video’s format—24 fps for film, 30 fps for YouTube, or higher for gaming and action shots. The key is to ensure that your audio and video settings are consistent from the start.

- Refining Audio Mix
Now that everything’s set, it’s time to mix your audio. Think about the sound you’re going for—what vibe and quality do you want? Pay attention to things like volume, balance, and where the sounds sit in the mix.
Before you start, clean up your tracks. Line them up, make a timeline, get rid of any silence, and cut out unwanted noise. If your computer is slow, try using a smaller video file to make things easier.
Start with the dialogue, then add the other sounds. Once it all flows nicely, bring in any extra effects. Adjust the volume, tweak the balance, and leave a little room at the top so you can fine-tune later. Listen to your mix on different devices to make sure it sounds good everywhere.
Conclusion
For successful vlogging, prioritize high-quality audio just as much as your visuals. Whether using a phone or a digital camera, a good lavalier mic can significantly improve your sound. With the right setup and tips, you’ll ensure your vlog audio is clear and professional.
