Ready to transform your audio with just a few clicks? Let’s dive in!

What are AI Audio Enhancers?

AI audio enhancers are AI-powered tools to improve your audio tracks. They basically help in removing background noises, enhancing voice clarity, balancing volume levels, reducing reverb, and boosting overall sound quality.

These tools use advanced machine learning algorithms to detect the original voice and the distortions automatically. Then they clean up the noise in real time or post-processing. These tools are useful for content creators, YouTubers, podcasters, musicians, online tutors, etc.

Examples of popular AI Audio Enhancers include Adobe Podcast, ElevenLabs Voice Isolator, etc.

How Do AI Audio Enhancers Work?

AI Audio Enhancers use deep neural networks and machine learning algorithms to analyze and boost your audio quality. First, when you upload your audio file, the AI analyzes your audio and detects unwanted noises, speech patterns, echoes, background noises, reverb, etc. 

Next, using its pre-trained models, it separates clear speech from distortions, such as wind, fan sounds, traffic, animal sounds, etc. Then, it boosts the vocal clarity of your original speech, making it more natural. 

Finally, it reduces echo and reverb and balances volume levels to avoid sudden silent or loud parts. You can then export the file in a format of your choice.

How I selected the Best Free AI Audio Enhancers

I first made a list of all the potential AI audio enhancers available for free. Next, I used a short interview clip with a lot of background noise and supplied it to each tool. This is the original audio recording.

At the end, I analyzed the outputs produced by each tool. Besides the audio quality, I also assessed each tool on its features, export capabilities, platform compatibility, free and paid tier limits, etc. Keeping all of these into consideration, I ranked the tools on my list.

In my opinion, the output quality is equivalent to Adobe Podcast. It cleans the background sounds with accuracy. However, the only downside is you need an ElevenLabs account to access it. Apparently, ElevenLabs is not offering free accounts to many Indians at the moment. 

So, if you already have an ElevenLabs account, you should definitely try it out!

You can only choose one of these options at a time. The output quality was pretty average in my opinion. But if you are working on simple projects and don’t want to sign up, this is a good option. 

Output:

Cons:

• Sign-up is required for downloading audio files.

I found its output quality pretty decent. It is good for beginners and hobby projects. But don’t expect high-quality audio on its free plan.

• Average output quality.

Pricing: The free plan offers Noise Removal and Auto Volume features with an audio enhancement limit of 20 mins/month. Its paid plan starts from $12/month for 600 minutes.

It features an array of tools, including voice cloning, voice duplication, editing, text-to-speech conversion, etc. To start with Altered Studio, head over to the Voice Editor and upload your file from your local device or Google Drive.
