SUMMARY:
We know VLC as an open-source media player for playing music and videos. Beyond its main function, it includes a feature that can extract audio from nearly all video container formats. It can create MP3s from formats like MP4, QuickTime, MKV, AVI, M4V, FLV, and more. Although it can convert video content to MP3, it faces certain conversion issues. These include an output file that has no extension and audio/video out of sync. In this post, we will teach you how to convert a video to MP3 with VLC. We will also show how to solve the most common VLC conversion. Before you start converting, always add the .mp3 extension to the output filename. Also, use the default Audio - MP3 profile unless you have specific encoding requirements.
VLC is one of the most frequently used media players. But to this day, many people don’t know it has a hidden feature. The Convert/Save tool has been inside the Media tab for a very long time. With it, you can extract audio from video in VLC. It re-encodes the video track out and saves just the audio data to your computer.
1. In VLC, go to Media and select Convert/Save to access the Open Media window. Go to File and click + Add to upload the video source. After you add the video, click the Convert/Save button to proceed.
2. In the Convert window, go to Profile, and select the Audio - MP3 profile. Click Browse next to Destination File to set the destination folder. After specifying the output directory, click Start to render the video.
Right after selecting the format, click the Wrench to adjust the bitrate to 192 kbps for excellent music quality. Then, set the sample rate to 44100 Hz to match CD-quality audio. If you’re planning to extract audio from MKV, there’s a high chance of compromising the quality. For lossless audio extraction, you'd better use dedicated software.
1. MP3 No Sounds After Conversion
An MP3 that has no sound after conversion is the most common issue. You run the conversion, but a file appears and plays in complete silence. Why does it happen? VLC tries to make a copy of the audio stream as is, without converting it.
To fix VLC convert video to MP3 with no sound: In the Convert window, click Edit selected profile (Wrench), then go to Audio Codec. Be sure the Audio box is checked, and the Codec is set to MP3. If the issue persists, try re-encoding the video to WAV, then convert WAV to MP3.
2. Conversion Progress Bar Gets Stuck
You click Start, the indicator bar moves, then it suddenly freezes at 0%, 50%, or 99%. This problem is mostly due to hardware acceleration issues, especially when converting UHD videos.
To fix: Go to Tools and select the Preferences to open the Simple Preferences window. Click the Input/Codecs tab and navigate to the Codecs section. Set the default Hardware-accelerated decoding settings to Disable, save the settings, then restart VLC.
3. Audio Sounds Distorted
The conversion finishes, but the audio sounds like it is playing underwater. This happens when there’s a sample rate mismatch between the source video and the output configuration. If you force VLC to downsample a video’s audio from 48 kHz to 44.1 kHz using an older codec, it will desync the timing tracks.
To fix VLC MP3 conversion quality settings: Open the Profile edition window by clicking Edit selected profile (Wrench). Go to the Audio Codec tab and keep the Sample Rate set to its original value. This forces VLC to match the exact frequency of the source file.
VLC's audio extraction feature is basic compared to those of audio converters. The following are some restrictions you might face when using VLC for this purpose:
In single-file mode, VLC converts video to MP3 quickly. However, as the saying goes, even the best horse stumbles. VLC is not for high-volume conversion or audio extraction. Also, it produces corrupted MP3s at times, fails on specific codecs, and stops rendering during long conversions. AnyMP4 Video Converter Ultimate is built to outperform all these performance limitations. With it, you can convert hundreds of videos to MP3 and 500+ other formats simultaneously, supporting both older and newer codecs. It uses advanced hardware-accelerated media processing to speed up the conversion by up to 120×. Also, it provides various profile presets that can match your source’s settings.

Here’s how to change MP4 to MP3 in VLC alternative:
1. Download AnyMP4 Video Converter Ultimate and complete the installation. After installation, go to the Converter tab and click +Add Files to upload the source video(s). You can load one or more video files at a time.
2. Go to the Output Format picker and select MP3 under the Audio Category. Next, choose a quality preset that matches your source's quality. To prevent audio distortion, select the Same as Source preset to extract the original audio track instead of re-encoding it.
3. Back to the main interface and enable Hardware Acceleration. Also, toggle the 120× Faster Conversion button to speed up conversions. Specify the file destination in the Save To field, then click Convert All to extract the audio from the video and encode it to MP3.
To assess AnyMP4's capabilities in terms of quality, batch conversion, and fast processing, we run hands-on testing. In our test, we use 10 UHD, 45 HD, and 45 1080p MP4 videos, totaling 1.82 GB. It took only 1 minute and 16 seconds to extract audio from the video. In our audit, we found no corrupted files, unplayable MP3s, or distortions.
Why is my VLC-converted MP3 file not playing on my iPhone?
Your converted MP3 files in VLC won’t play on your iPhone due to iOS file-sandbox restrictions. It prevents native apps from detecting locally downloaded or transferred files.
How do I keep the highest audio quality when converting video in VLC?
To keep the highest audio quality, prevent VLC from re-encoding the audio tracks. You can achieve this by copying the original tracks to your new container.
Can I batch-convert 50 videos to MP3s at once with VLC?
Yes, you can batch-convert 50 videos to MP3s at once using VLC's built-in Convert/Save feature. However, it converts files sequentially, which takes time for 50 large videos.
VLC converts to MP3, but the output is still an MP4 file, how do I fix this?
Before conversion, be sure you manually type .mp3 at the end of the file name in the Destination File field. If you only change the profile to MP3 without specifying the correct file extension, VLC will wrap the audio in an MP4 container.
What is the best bitrate to choose for MP3 in VLC settings?
The best bitrate for MP3 in VLC settings depends entirely on your source. For music and Hi-Fi audio, the recommended bitrate should range from 192 to 320 kbps.
Is VLC Media Player safe to use for file conversion?
Yes, VLC is safe to use for file conversion. However, VLC itself is open-source and free of spyware. It means hackers have been known to distribute compromised versions of VLC via unofficial download sites. So, always verify your download source.
In this guide, you've learned how to convert videos to MP3 with VLC. To get an error-free MP3, use the appropriate audio settings and master the solutions we have provided. VLC is a useful program that you can download for free. However, it lacks file extensions, fails to convert some files, and provides limited batch-processing support.
