Quick Findings

• Adobe Podcast is a robust option for professionals needing a background noise remover.
• Audacity is a background tool you would love if you need a free and open-source tool.
• Podcastle AI is the background noise removal tool implementing the most artificial intelligence.

1. Adobe Podcast – Great for Creative Professionals

Adobe’s suite of applications is extremely popular among creative professionals. So, when Adobe launched a new service called Podcast, we were certainly intrigued. And boy, is it impressive! Despite the service being in beta, it works wonders on any audio. It offers two main features: Enhance and Mic Check.

For the scope of this article, we’re focusing only on the Enhance feature. Once you upload an audio file onto the online portal, it will undergo processing, after which you can download it. We’re unsure what sorcery Adobe is running in the background, but the background noise removal works like magic.

It’s so good that it seems like your audio was recorded in a professional studio environment. If you want to remove the background noise from any audio or voice recording, this is an excellent tool that does it for free. You can upload an audio track up to an hour long and under 1GB. The supported formats are MP3 and WAV.

2. Krisp.ai – Real-Time Audio Processing

Unlike Adobe Podcast, Krisp is an app that reduces background noise and interference during online meetings. It processes your audio in real time and makes it cleaner so that participants in the meeting can hear you better. Whether it’s your family members murmuring or your baby crying in the background, Krisp removes the noise to make your audio sound more professional.

It’s an app that lives in the menu bar on your computer, along with a toggle to enable or disable noise cancellation. It’s free of cost and is an excellent tool if you take many calls daily. You can integrate Krisp into Google Meet, Microsoft Teams, Discord, Skype, Slack, and any application or service you use for audio or video calls.

While you cannot use Krisp to remove noise from a pre-recorded audio file, we can assure you that it will become a must-have app for you during online meetings or classes.

3. Aspose – Online Background Noise remover

This tool filters background noise from audio from a wide range of file formats, which is its biggest USP. The supported file formats are — AAC, AIFF, FLAC, M4A, MP3, WAV, WMA, AC3, CAF, and OGG. Generally, most services are restricted to MP3 and WAV.

Since the service is completely online, there’s no requirement for a separate file to be downloaded onto your device. This makes Aspose compatible with any device with a browser. If you want to remove background noise from audio online for free, and the file format is not supported on Adobe Podcast or the size is big, you can use Aspose as an alternative.

You can also choose the output file format of your choice. Besides the ability to remove background noise from voice recordings, Aspose also has some other free tools that you can use. It has a text-to-speech engine, compressor, splitter, merger, and audio converter. So, you’re getting a complete suite of audio editing tools.

4. Audiodenoise – Great Customization Options

While Adobe and Aspose do a great job of removing background noise from audio, they do not give you any customization options. Audiodenoise fixes that by allowing you to set various parameters for your processed audio. You can set the amount of noise reduction, choose the model based on which the noise reduction will occur, and also set the gain, block size, etc.

The interface is straightforward, and the website is completely free. There are no ads on the site, either. Before you upload your file, you can also test out the various demo files on the website to get an idea of what your audio will sound like after the background noise removal.

You can opt for this service if you want granular control over your audio processing.

5. Audacity – Open-Source Audio Tool

If you need an open-source background noise removal tool, Audacity should be your first call. This app allows you to create a noise profile from a silent part of the audio and then use it to detect what unwanted noise should be removed from the rest.

Using this tool, you can selectively target parts of the audio where noise is present. It is feature-rich, but newbies may be weary of its steep learning curve. What we love most is that it lets you preview your chosen adjustments before applying them. This way, you can fine-tune the settings and get the optimal results.

This is also the ideal tool if you need to walk on very large audio files, as it is free without limitations.
