Voice Cleaner Software - Our Top Picks for 2025

There’s nothing more annoying for a listener than hearing unwanted noise during a recording. Lip smacking, umms and ahhs, and shaky recording quality can really ruin the listening experience. Not to forget, cleaning up audio can be extremely tedious.

The good part? There are a number of tools to help you remove unwanted sounds easily. And that’s what we’ll be discussing today.

We’ll provide you with detailed overviews of the best voice cleaner software (including our very own Cleanvoice).

Let's dive deeper into different features of each tool before you make the right choice.

What is a Voice Cleaner?

A voice cleaner is a software or online service that cleans up voice recordings by removing things like lip-smacking, clicks, umms, and ahhs, improving muddy audio, and more. They help you attain a better quality audio recording and a better experience for your listeners.

Generally, many voice cleaner software also provide additional functionality like removing background noise or long periods of silence during recordings, streamlining your entire editing process.

As an example, Cleanvoice comes with a filler word remover feature, which can clear up the flow of your recordings automatically with AI audio cleanup. The AI identifies and removes filler words automatically and adds room noise to make your recording more natural. Pretty neat, if we do say so ourselves!

Why Are Voice Cleaners Important for Podcasts?

  • Improve speech clarity: Podcast recordings often contain imperfections that affect the clarity of your spoken words. Using voice cleaners help reduce or eliminate these sounds, which results in enhanced speech clarity.

  • Correct recording errors: When recording a podcast, you may make mistakes such as long pauses, stuttering, or mouth sounds. By using a voice cleaner, you can easily edit and re-record sections for a seamless listening experience.

  • Streamline the editing process: Since many of these tools enable the uploading of complete audio recordings to their platforms and automatically remove unwanted sounds, users spend less time editing audio.

Factors To Consider When Choosing A Voice Cleaner

As of 2025, there are over 5 million podcasts with over 70 million episodes. 

As a podcaster, you must choose software that helps you deliver the best listening experience for your audience. Let’s look at some of the criteria you should look at before making your choice:

1. Automatic Audio Enhancement

Recording a podcast is more than just pressing the record button and talking – there are various tasks involved, such as adjusting audio levels and equalization, removing background noise or echo, and more.

Choosing the best AI audio cleanup tool with an automatic audio enhancement lessens your tasks as it eliminates the need for manual adjustments and fine-tuning.

2. Multi-Track Noise Remover

When choosing a voice cleaner tool, software with a multi-track noise remover feature should be at the top of your list. This feature removes unwanted background noises such as hums, echoes, or hisses from your recording.

With Cleanvoice’s multi-track noise remover, you can remove noises from each individual audio track, which is especially useful if you have multiple participants recording their audio separately.

Online service LALAL.AI also removes noise and background music easily. Its special algorithm eliminates unwanted sounds, creating tracks with clear voices.

3. Timeline Export

Cleanvoice has a timeline export feature that allows you to export the timeline in the editor and show you what the tool would like to edit.

The timeline export feature is perfect if you are working with editors, producers, or other team members in your podcast production process. This allows everyone to easily navigate the tracks, and facilitate seamless edits, revisions, and adjustments.
