Denoiser

In the voiceover world, a Denoiser is a tool or software. It helps remove unwanted background noise from audio. Many voiceover artists find it very useful for making their recordings sound better.

Dynamic microphones like the SM7B or RE-20 can have background hiss. This can be hard to get rid of, even with the best equipment. But, tools like Waves NS1 or RX7 can help reduce this hiss and make the sound clearer.

Using a Denoiser, even with a dynamic or condenser microphone, can make a big difference. It can make low-quality recordings sound much better.

For top-notch voice recordings, the goal is to keep the noise floor at -60dB or lower. It's best to keep the peak volume between -12dB to -6dB during recording. The average volume should also stay below -60dB when not speaking.

To make a quiet recording space, use sound-absorbing materials and big-diaphragm condenser microphones. Keep the microphone 6-8 inches away for the best results.

Tools like Waves Clarity VX and iZotope's RX 10 Advanced are great for cleaning up background noise. But, they're best used in post-production, not during live recordings. Using them carefully helps keep the audio quality high.

Recording some room noise can help with noise reduction later. Tools like Audiate by TechSmith make recording and reducing noise easy. But, some free apps might need you to know a bit about audio editing first.

Try to avoid distractions like traffic noise or fans running. By doing this and using the right tools, voiceover artists can greatly improve their recordings.

Tips for reducing background noise during recording

Recording high-quality audio means you need to cut down on background noise. Here are some tips to help you get clear recordings without unwanted sounds.

1. Take a Moment for Room Tone Recording

Before you start recording, record 10-20 seconds of just the room. This helps you find and fix any background noise later.

2. Invest in High-Quality Equipment

Good microphones, stands, and pop filters make a big difference. They help you get clear recordings and cut down on noise.

3. Control Microphone Settings

Change your microphone settings to reduce background noise. For Windows, go to Control Panel > Hardware and Sound > Sound > Recording section to find these settings.

4. Create a Noise Profile

Record a few seconds of silence before speaking. This helps your editing software find and remove background noise.

5. Utilize Noise Reduction Software

Tools like Audacity, Wavosaur, Samson Sound Deck, or Wavepad are great for editing out noise. They let you set up your noise reduction just right for your recordings.

6. Isolate and Position Your Microphone

Move things around to cut down on noise. Make a quiet space for recording and keep distractions away.

7. Record Noise Samples for Each Podcast Host

If you're recording with different hosts, record a noise sample from each one. This helps you fix noise for each recording.

Using these tips, you can make your recordings clear and free from background noise. This way, you get professional-quality audio.

Techniques for reducing background noise in post-production

After you record your audio, it's time to make it sound better. Here are some ways and tools to help you do that:

Noise reduction software: Use tools like Krisp and DeNoise to get rid of background noise. They let you control how much noise you remove, making your audio clear.

Noise reduction in digital audio workstations (DAWs): DAWs like Audacity, Adobe Audition, Pro Tools, and Logic Pro have built-in tools for noise reduction. These tools help you get rid of background noise and make your audio sound better.

Manual audio filters: Use manual filters like high-pass and low-pass to cut out unwanted sounds. These filters help you remove sounds you don't want, making your audio cleaner.

Specific tools and features: Adobe Audition has special noise reduction features, like the Noise Reduction effect. This effect can boost the signal-to-noise ratio by 5 to 20 dB, keeping your audio quality the same. You can also adjust the reduction in different sound ranges to keep the audio you want.

By using these methods and tools, you can make your recordings sound professional. This makes your audio quality much better in post-production.
