We Share How to Remove Distortion from Audio (with Cleanvoice & Audacity)

Quick Summary

In this guide, we explain what causes distortion, why it matters, and how to fix it step by step. You’ll learn how to repair clipped audio manually in Audacity, as well as how to remove distortion faster using Cleanvoice’s AI-powered Studio Sound.

If you want clearer, more professional sound, this walkthrough shows you exactly how to get there.

Dealing with Distorted Audio that Ruins Your Recordings?

A single distorted sentence can undo 30 minutes of perfect delivery. And you won’t even notice that while recording, but your audience will notice it immediately.

Which is why you need to check your audio and remove any distortion present before publishing.

Don’t know how to do that? Keep reading this Cleanvoice blog to see how you can remove distortion from your audio in two different methods.

But first…

What Causes Distortion in an Audio?

Audio distortion usually happens when your signal goes beyond what your gear or software can handle. This clipping cuts off the tops and bottoms of the sound wave when levels are too high or gain is set improperly, creating harsh, unpleasant audio.

It also comes up in your audio when your microphones, preamps, or interfaces are overloaded, or when loud sources are too close to the mic. These conditions force the system past its limits, so it can’t record or reproduce the waveform accurately.

Why Should You Remove Distortion from Audio?

• Improve clarity and intelligibility: Distortion makes speech hard to understand. Cleaner audio helps listeners follow your content with ease.
• Enhance professionalism: Clean, undistorted sound shows you prioritize quality. It strengthens your brand image and keeps your listeners engaged.
• Increase listener retention: Harsh or clipped audio can drive audiences away. Removing distortion makes episodes more enjoyable to stay tuned for.
• Prevent ear fatigue: Distorted sound causes listener discomfort over time. Clean audio feels smoother and more natural.
• Boost platform performance: Clear audio transcribes better and performs more consistently across playback devices.

How to Remove Distortion from Audio

Method 1: Remove Distortion from Audio with Cleanvoice

Step 1: Upload Your Distorted Audio to Cleanvoice

Go to the Cleanvoice dashboard, where you’ll land on the Upload screen.

Drag and drop your distorted audio file into the upload box, or click browse files to select it manually. Cleanvoice supports almost all audio formats.

You can also import your file from:

• Your Device
• A direct link
• Google Drive
• Direct audio recording

Once your file appears on screen, click "Upload 1" file. You can also upload multiple files as a batch.

No manual setup. No complicated configuration.

Step 2: Select the Right Template for Distortion Removal

Now decide how Cleanvoice should treat your audio. This step determines how aggressively distortion and harsh peaks are reduced.

On the template screen, choose "Clean All & Enhance (Studio Sound)" under Default templates. This is the recommended option for distorted recordings.

• Studio Sound:

  • Reduces harsh peaks and clipped tones.
  • Smoothens vocal texture.
  • Enhances clarity and balance.
  • Makes your voice brighter or softer, depending on the audio.

• If you want more control over your edits, click on "+ New custom template."

• In the Edit section, keep cleanup tools like Long Silences, Stutters, and Mouth Sounds enabled.

• Then move to Enhance and make sure Studio Sound and Normalize are selected.

• For most creators, the Standard Studio Sound option works best. It improves clarity without overprocessing your voice.

Lastly, export your file based on your end goal. For social media, turn on options like Transcription, Summarize, or Social Content. Choose the format that fits your needs, such as MP3, WAV, or FLAC.

Once selected, click "Create Template" to finalize your selections.

Step 3: Let Cleanvoice Process Your Audio

Now step back and let our AI do the heavy lifting. Once you click Start Processing, Cleanvoice begins analyzing your file.

You’ll see a progress screen showing:

• File name
• Processing percentage
• Status updates

Cleanvoice applies Studio Sound, peak control, and normalization automatically. It detects distortion, reduces harsh clipping, and balances levels across the entire recording.

You don’t need to monitor every second. You can safely close the page. Cleanvoice continues processing and notifies you when it’s complete via email.

This stage replaces manual waveform editing and complex repair tools. Our AI handles it consistently and fast.

Step 4: Review and Download Your Cleaned Audio

Your file is ready. Cleanvoice shows a detailed breakdown of what the AI cleaned up, including:

• Dead air cut (in seconds)
• Breaths minimized
• Filler words removed
• Stutters and mouth sounds corrected

Now confirm the distortion is gone and your voice sounds clean before publishing. Take a minute to:

• Play the file inside Cleanvoice
• Compare before and after playback
• Listen on headphones and speakers

On the screen, click Download Audio to get your enhanced file immediately.

Once you’re satisfied, save the file to your project folder. Your audio is now balanced, clearer, and ready to publish.

Method 2: Remove Distortion from Audio with Audacity

Step 1: Open Your Audio in Audacity

Start by launching Audacity on your computer. If you haven’t installed it yet, download the latest version from audacityteam.org and install it first.

Once open:

• Click File > Import > Audio

• Select your distorted audio file

Audacity will load the waveform into the timeline.

This visual representation shows peaks and valleys. You can already see where distortion may occur if the waveform is “squared off” at the top or bottom. With your file open, you’re ready to start correcting distortion.

You can also import your audio from Cleanvoice directly into Audacity. This skips manual import and speeds up your workflow when switching tools.

Step 2: Check Levels and Prevent Further Clipping

Before repairing distortion, lower the overall level to prevent further clipping during processing.

Press Ctrl + A to select the entire track. Then go to Effect > Volume and Compression > Amplify.

In the Amplify window, enter a negative value such as -3 dB. Make sure “Allow clipping” is unchecked.

Click Apply.

This reduces the track’s overall volume and gives you headroom before applying distortion repair. It doesn’t remove existing distortion, but it prevents additional processing from pushing peaks further into clipping.

With safe levels in place, you can now apply Clip Fix confidently.

Step 3: Identify and Fix Clipping with Clip Fix

Clipping is the most common form of distortion in audio. In Audacity, you fix this with Clip Fix, which reconstructs distorted peaks so the waveform looks and sounds more natural.

First, click anywhere on the track and press Ctrl+A to select the full audio. Then go to Effect > Noise Removal and Repair > Clip Fix in the top menu.

In the Clip Fix window, set the Threshold to around 0.9. This tells Audacity how much of the waveform needs reconstruction.

Click Apply.

Audacity will smooth clipped waveform tops that cause distortion. After it finishes, play back the audio and listen for improvement before moving to the next step.

Step 4: Apply Compression to Smooth Levels

Uneven volume makes distortion stand out. Compression evens out loud and quiet parts so your track sounds more consistent.

First, select your entire track using Ctrl+A. Then go to Effect > Volume and Compression > Compressor.

In the Compressor window:

• Set Threshold slightly below your average peak
• Choose a Ratio around 2
• Leave Attack and Release at default

Click Apply.

Compression reduces big spikes and balances levels across your audio. It doesn’t remove distortion itself, but it makes distorted sections less noticeable and gives your voice a more controlled tone.

Listen back to confirm changes before moving on.

Step 5: Reduce Harsh Frequencies with Equalization

Distortion often makes voices sound sharp or tinny. Use Audacity’s Equalization to smooth those frequencies and improve clarity.

First, select your full track with Ctrl+A. Then go to Effect > EQ and Filters > Filter Curve EQ.

In the Filter Curve window:

• Lower bands around 2–6 kHz to soften harsh tones
• Slightly boost lower mids (around 200–300 Hz) for body

Click Apply and play your audio. Again, this doesn’t remove distortion itself, but makes distorted sections less aggressive and easier to listen to.

Adjust the curve in small steps and preview changes to avoid unnatural tone shifts.

Step 6: Export Your Cleaned Audio

After repairing distortion and polishing your track, export it properly so that the audio quality stays high.

Go to File > Export Audio….

Then choose your preferred export option:

Next, in the export window:

• File name: give a clear name (e.g., “cleaned_audio.wav”)
• Format: WAV (Microsoft) for best quality
• Channels: Stereo (use Mono only if your project is mono)
• Sample rate: 44100 Hz (standard for podcasts and most audio)
• Encoding: Signed 16-bit PCM (highest compatibility)

Ensure Export Range: Entire Project is selected.

Click Export and save the file. This preserves speech clarity and avoids new distortion from incorrect format settings.

Best Practices for Removing Distortion from Audio

Work in Passes, Not One Fix

Don’t expect a single tool or step to solve all distortion issues.

First correct clipping or peak distortion, then smooth harsh frequencies, then adjust dynamics. Treat each pass as a focused edit with its own goal.

Revisit earlier stages if later steps reveal new issues. This layered approach prevents overcorrection and keeps edits precise.

Reference Multiple Playback Systems

Your ears adapt to different sound environments, so always test cleaned audio on different sound systems/devices. After processing, listen on studio monitors, headphones, laptop speakers, and mobile devices.

A fix that sounds good on one device may still show distortion or harshness on another. Checking multiple systems makes sure your edits translate well to real-world listening.

Use Minimal Corrective EQ Curves

When using equalization to control harsh tones, less is more.

Large, aggressive boosts or cuts fix one problem but can introduce new ones. Focus on surgical adjustments only where needed. Small cuts around problematic frequency bands tame biting highs without making your audio sound hollow or unnatural.

Monitor Metering, Not Just Ears

Don’t rely solely on listening; use visual feedback from meters and waveform displays too.

Watch amplitude peaks and average levels while you fix distortion. When clipping disappears visually, and meters sit comfortably below max levels, you get a more accurate picture of what’s fixed.

This combined approach prevents surprises when you export the final audio.

Save Version Checkpoints

Instead of overwriting a single file, export intermediate versions at key stages, e.g., after distortion repair, after EQ, after compression. Name them clearly so you can easily return to earlier checkpoints if a later adjustment needs re-evaluation.

This versioning protects your workflow and gives you flexibility to compare changes without undo chaos.
