Oftentimes, your audio files or the sound captured from your microphone suffer from noise caused by a loud environment or a location that causes an echo. To address these issues without having to re-record the audio, there are software solutions that can assist with these problems with 100% certainty!
Check out the content below where we explain three highly effective different solutions that help to remove the echo or reduce noise from the audio in various ways: DaVinci Resolve, Adobe Podcast, and Nvidia RTX Voice!
1. DaVinci Resolve
DaVinci Resolve is a free software available for Windows, macOS, and Linux systems. It’s renowned as a multifunctional software combining professional editing, color correction options, visual effects incorporation, motion graphics inclusion, and comprehensive sound post-production.
In this software, we find everything for sound post-production on the Fairlight page, including various professional tools. Here, you essentially have a digital audio workstation (DAW) entirely integrated into DaVinci Resolve.
Removing Echo or Noise – Method 1
First, let’s explain how to remove noise from an audio or video using DaVinci Resolve. Check out the steps below:
- Open an audio or video file using the software, either through the “file” menu by selecting “open”, or by dragging a file into the software window
- With the file loaded on the timeline, select the “Fairlight” menu from the options in the lower central area of the window
- Select the audio track you wish to correct in the central area of the window
- On the left side, in the “Mixer” menu, find the “Effects” row and click on the “+”
- Go to the “Restoration” menu, and click on the “Noise Reduction” option
- In the window that opens, there are two methods that can be done to remove the noise
- The first is to click on the “Learn” button for the software to automatically analyze where it needs to remove the noise
Removing Echo or Noise – Method 2
The second technique is by clicking on the “Auto Speech Mode” option and then closing the window
Removing echo from an audio file for free is also easy. Check out the steps below:
- After opening the file in DaVinci Resolve, select the audio clip and go to the “Inspector” menu in the upper right corner of the window
- Click on the “Audio” tab and activate the “Equalizer” option further below
- Activate the “Band 1” and “Band 4” options
- In the “Band 2” and “Band 4” options, select the second symbol from the dropdown menu, with a small pentagon, changing the “Q” menu values to 2.0 or 2.5
- In the bluish chart above these options, select points 2 and 3 and adjust downward from the center line while you listen to the audio, modulating to the point where you feel the echo has completely disappeared.
- And there you have it, your file is corrected. To export the final file, go to the “File” menu and select the “Save As” option.
2. Adobe Podcast
Adobe has a free online tool called Adobe Podcast that removes noise and echoes from your audio using artificial intelligence technology developed by the brand.
The process is incredibly easy, and you don’t need any technical knowledge, let alone install software on your computer, which greatly simplifies the process. Check out the steps below.
- Access the Adobe Podcast platform through your web browser. In the window that opens, you need to quickly sign up for free on the Adobe platform to access the service. If you prefer, you can access the service by logging in with your Google or Facebook account, or by using the auto-login feature provided by Apple for computers using that system
- After creating your account, log in with the registered email and password
- After that, you’ll see an area to access files from your computer, or drag a file into the window
- Open the file one of these two ways, remembering that the system only accepts files in MP3 or WAV format, with a maximum length of 1 hour or a maximum size of 1GB
- The audio will be analyzed and enhanced by the tool, which can take a few minutes depending on the size of the file
- At the end of the analysis, Adobe Podcast provides a small player for you to play the final result, as well as a “download” button to download the corrected file
See how easy it is? The Adobe Podcast tool does all the work for you automatically, removing or reducing noise and echoes from your audio. As of February 2023, the service is still in Beta and is offered entirely free of charge.
3. Nvidia RTX Voice
Nvidia RTX Voice is a program created by Nvidia, a renowned developer and manufacturer of software and video or sound cards widely used in computers around the world.
RTX Voice was developed as a plug-in that uses artificial intelligence to allow individuals to capture sound via microphones more cleanly, suppressing noise and interferences that affect the final recording quality.
To use this software, you need to use a computer with a Windows operating system, as well as Nvidia GeForce RTX or Quadro RTX graphics cards. Here’s a step-by-step guide to using this solution:
- Visit the RTX Voice page and look for the “Installation Guide” menu, or if you prefer, click directly here to download
- Accept the Nvidia license to use the tool and finish the software installation
- Open the Nvidia RTX Voice software
- Select the microphone and speaker you want to use for noise suppression
- In the programs that you will use to capture audio, go to the settings, find the video and voice menu and check if the selected microphone is called “Microphone (NVIDIA RTX Voice)”
- If the program you’re using offers a “noise reduction” option, disable it to prevent interference with RTX Voice
That’s it, you’re ready to use your microphone.
With these 3 tips on different tools, we’re confident that you’ll be able to remove noise or echo from your sound files, facilitating any editing you need to do for personal or professional use, and achieving the result of clear, clean audio!
