Make dialogue, voiceovers, and podcast recordings easier to follow with Kapwing's one-click voice editing tools. Use Enhance Voice to improve vocal clarity, or Split Vocals to separate speech and singing from background audio so you can adjust each track individually.
Remove long pauses and awkward gaps automatically with Smart Cut, keeping conversations and spoken content moving without cutting every silent section manually. Combine these tools to improve voice recordings and create more focused audio for videos, interviews, and podcasts.

Balance volume and blend audio tracks
Sudden volume changes and poorly mixed audio can distract from an otherwise good recording. Kapwing's Equalize Volume tool evens out inconsistent sound levels, while individual volume controls let you balance dialogue, music, and sound effects.
For more precise editing, right-click in the timeline to detach audio and adjust sound separately. Add fade-ins and fade-outs to smooth transitions between clips and songs, or use Kapwing's online audio editor to trim, split, and combine multiple audio tracks.

Frequently Asked Questions
We have answers to the most common questions that our users ask.
Is the Audio Enhancer free?
Kapwing offers many audio editing tools for free, like the automatic volume equalizer. However, to use the full range of AI tools, Kapwing's Audio Enhancer requires a Pro account.
How can I improve my audio quality?
There are several steps you can take to improve your audio quality. For starters, consider using a high-quality microphone to record your audio. Keep in mind your recording environment, ensuring that the room has good sound isolation and minimal background noise.
After recording, you can enhance your audio quality using tools like Kapwing. Upload your recording to Kapwing's online audio enhancer, then choose the adjustments that match the problem. Use Clean Audio to reduce background noise, Enhance Voice to improve speech clarity, or Auto Level Volume to balance loud and quiet sections. Preview your changes, make additional edits if needed, and export the improved recording.
How do I clear fuzzy audio?
To clear fuzzy audio, you can use a high-quality audio enhancement tool like Kapwing. It can help to reduce background noise, boost the overall clarity and audio quality of the file, and make the audio easier for your audience to listen to. You should also consider some tips during the audio recording process to try and prevent fuzzy audio from happening in the first place, like microphone positioning, using a pop filter, and adjusting recording settings on your devices.
Are there real-time audio enhancers for video calls?
There are several real-time audio enhancers for video calls that clean up your microphone audio live as you speak on Zoom, Microsoft Teams, Google Meet, or other platforms:
- Teams, Zoom, and Google Meet have built-in, native settings for audio enhancement in real time. Google's "Studio Sound" setting is available under Settings > Audio. The Zoom app suppresses background noise by default, adjustable in Settings > Audio.
- Zoom has apps like Krisp available in their app marketplace to offer real-time noise cancellation and echo removal
- After recording a video or audio track, upload to an editing service like Kapwing to download with enhanced audio.
How can an audio enhancer improve your audio files?
An audio enhancer can improve the overall sound quality of your audio and video files through the use of various filters, adjustments, and editing:
- Improve voice tracks: Boost vocal clarity with the Enhance Voice feature. Increases mid-to-high frequencies to reduce the muddiness.
- Remove background noise and boost quieter voices
- EQ (Equalization) and leveling: Normalize volume in seconds with Auto Level Volume. Correct the volume across multiple different layers in the timeline. AI identifies the volume in each track and makes tweaks to balance it across speakers.
- Removing glitches: Creators can add in keyframes to reduce breaths, hisses, hums, or pops in their audio.
A high-performing audio enhancer like Kapwing can reduce or eliminate background noise, enhance clarity, balance audio levels, and add effects. Overall, your audio files will be more clear, engaging, and professional.
How do I make quiet or muffled audio clear?
Start by identifying what's making the recording difficult to hear. If speech is too quiet, increase or balance its volume using Kapwing's audio equalizer. If background sounds interfere with dialogue, try Clean Audio or Enhance Voice. Audio enhancement can improve clarity, but severely distorted or poorly recorded speech may not be fully recoverable.
Can I use an audio enhancer for music and songs?
Yes. Kapwing lets you adjust music volume, trim audio, and edit multiple sound tracks in your browser. You can also separate vocals from instrumentals with the Split Vocals tool to edit them individually. However, these adjustments are not the same as professional music mastering, and an audio enhancer cannot restore detail permanently lost through heavy compression.
What file formats can I enhance with Kapwing?
Kapwing supports common audio formats including MP3, WAV, M4A, FLAC, and OGG, along with video files such as MP4. Upload your file directly into the browser-based editor, make your audio adjustments, and export the completed project as an MP3 audio file or MP4 video. You don't need to convert supported files before uploading.
What's the difference between manual and AI audio enhancement?
AI audio enhancers automatically analyze recordings to identify and reduce unwanted noise, improve speech clarity, and balance sound levels with less manual work. Traditional audio editing gives you more direct control over enhancements like volume, trimming, and individual audio tracks.
AI enhancement is useful for quickly cleaning up voice recordings, podcasts, and video dialogue, while manual editing works well for precise adjustments to music, sound effects, and mixed audio. Kapwing supports both approaches, so you can use its AI Audio Enhancer alongside studio enhancement tools in the same project.
