You’ve recorded a podcast or spent a lot of time on narrating a documentary or audiobook and it’s time to edit. You load in your audio and there it is. Background hum. It’s like the digital leaky faucet. We’ll walk through on how you can avoid it from the get go, and if you can’t then you can clean up your audio during post-editing, with some cool AI audio clean up tools.

Background noise is every audio creator’s nemesis. Whether you’re a podcaster, YouTuber, musician, or app developer, unwanted sounds like humming, chatter, or static can ruin the listening experience. But don’t worry—removing background noise has never been easier, thanks to advanced AI tools designed to clean up your audio effortlessly.

In this article, I’ll guide you on how to remove background noise and review the top 5 AI audio cleanup apps that make this task easy and effective. Spoiler alert: PlayHT is hands-down the best option for balancing simplicity, power, and results.

Why Is Removing Background Noise Important

Audio is a huge part of how people experience content. Poor-quality sound—filled with noise—can distract listeners and reduce the professionalism of your work. Clean audio ensures:

  • Better clarity: Your voice or music is front and center.
  • Higher engagement: Listeners are more likely to stick around.
  • Professional quality: Essential for podcasts, interviews, or any project where sound matters.

How to Remove Background Noise From Audio

Removing background noise comes down to two factors: preventive measures while recording and post-production cleanup using AI tools. Here’s how to do both:

1. Record in a Noise-Free Environment

While AI tools can work wonders, it’s best to minimize noise at the source.

  • Use soundproofing materials like foam panels.
  • Record in quiet spaces, away from fans, air conditioners, or other consistent noise sources.
  • Invest in a good-quality microphone that isolates sound.

2. Use an AI-Powered Audio Cleanup Tool

Even in the best recording environments, some background noise can creep in. This is where AI noise removal tools shine. These apps are trained to identify and remove unwanted sounds while preserving the quality of the main audio.

3. Enhance the Cleaned Audio

Once the noise is gone, use audio editing techniques like EQ (equalization) and compression to further improve clarity. Many cleanup tools, like those we’ll cover, handle this automatically.

The Top 5 AI Audio Cleanup Apps (With PlayHT Leading the Pack!)

Now, let’s dive into the best tools for removing background noise. These apps are designed for everyone, from casual creators to developers building custom audio solutions.

1. PlayHT: The Top Pick for AI Audio Cleanup

PlayHT isn’t just a text-to-speech powerhouse—it’s also a leader in audio processing. Its noise removal features are powered by cutting-edge AI, making it the best option for creators and developers looking to clean up audio efficiently.

What sets PlayHT apart is its ability to remove background noise while maintaining the natural richness of voices. Whether you’re editing a podcast, fixing user-generated content, or building an audio platform, PlayHT makes it easy to clean up recordings in minutes.

Key Features:

  • AI-Powered Noise Reduction: Removes background noise, hum, and static effortlessly.
  • Preserves Voice Clarity: Unlike some tools that make voices sound robotic, PlayHT ensures voices remain clear and natural.
  • Developer-Friendly API: Developers can integrate PlayHT into their own applications for automated audio cleanup.
  • Fast and Scalable: Perfect for large-scale projects or batch processing.

Why PlayHT is the Best Choice:

PlayHT’s combination of ease of use, affordability, and professional-quality results makes it the best tool for creators and developers alike. With its API capabilities, it’s also perfect for scaling up audio cleanup in larger workflows.

2. Adobe Podcast Enhance

Adobe’s Podcast Enhance is designed to give amateur recordings a professional edge. This AI-powered tool is part of Adobe’s audio suite and specializes in making voices sound studio-recorded, even if they were captured in noisy environments.

Key Features:

  • Studio-quality voice enhancement.
  • Noise removal tailored for podcasts and interviews.
  • Seamless integration with Adobe’s Creative Cloud.

Drawbacks:

While it’s great for podcasts, Adobe Podcast Enhance is less versatile for music or multi-track audio projects. Additionally, its pricing can be steep if you’re only using it for occasional cleanup tasks.

3. Krisp: Best for Real-Time Noise Suppression

If you need real-time noise cancellation for live calls, streams, or meetings, Krisp is your go-to tool. It’s designed to remove background noise while you’re speaking, making it perfect for virtual meetings or online teaching.

Key Features:

  • Removes background noise in real time.
  • Works with popular conferencing tools like Zoom, Teams, and Google Meet.
  • User-friendly with minimal setup.

Drawbacks:

While Krisp excels at live noise suppression, it’s not as feature-rich for post-production cleanup. If you’re working with pre-recorded audio, other tools (like PlayHT) offer better options.

4. Dolby.io Media Processing API

Dolby.io brings Dolby’s legendary audio expertise to developers. This API offers high-end audio cleanup capabilities, including noise reduction, dynamic leveling, and spatial audio enhancements.

Key Features:

  • Professional-grade noise reduction.
  • Ideal for developers building custom audio solutions.
  • Advanced customization for audio processing.

Drawbacks:

Dolby.io’s API is powerful but complex. It’s best suited for advanced users or teams with technical expertise. The pricing can also add up for small-scale projects.

5. Auphonic: Automated Post-Production for Podcasts

Auphonic is a favorite among podcasters for its automated post-production features. It not only removes background noise but also handles volume leveling, EQ adjustments, and audio mastering.

Key Features:

  • Multi-track audio processing.
  • Automated leveling and mastering.
  • Cloud-based, no installation required.

Drawbacks:

While Auphonic is excellent for podcasts, it’s less developer-focused and not as versatile for other types of audio projects. Its reliance on automation can also limit customization.

How to Choose the Right Tool

Choosing the best tool depends on your specific needs:

  • For All-Around Performance: PlayHT is the best choice for professional-quality results with minimal effort.
  • For Live Noise Suppression: Krisp is perfect for real-time use.
  • For Advanced Customization: Dolby.io offers unmatched control for developers.
  • For Podcasting: Auphonic and Adobe Podcast Enhance both cater specifically to podcasters.

Pro Tips for Better Results

Even with the best tools, a little preparation can make a big difference:

  1. Use a Pop Filter: Reduces plosive sounds (like “P” and “B”) and keeps the mic clean.
  2. Test Your Recording Setup: Eliminate unnecessary noise sources before hitting “record.”
  3. Tweak Settings: Most AI tools offer adjustable noise reduction levels—find the sweet spot that removes noise without affecting voice quality.

Removing background noise doesn’t have to be a headache. With AI tools like PlayHT, Adobe Podcast Enhance, Krisp, Dolby.io, and Auphonic, you can clean up your audio and make it sound professional in minutes.

Among these, PlayHT stands out as the top choice for its user-friendly design, powerful AI, and ability to preserve the natural clarity of voices. Whether you’re a creator or a developer, PlayHT is the ultimate tool to elevate your audio quality.
