Extracting audio from video
VLC Media Player is a free and open-source media player available on both Mac and Windows. It is a versatile tool that can be used to extract audio from video files in common formats like MP4, and save the extracted audio in MP3, OGG, and other formats.
The process to extract audio from a video using VLC is straightforward, but there are slight differences between the Windows and Mac versions. Here is a general guide:
- Open VLC Media Player: On Mac, click on "File" and scroll down to "Convert/Stream…". On Windows, click on "Media" and select "Convert/Save".
- Select Video File: Click "Open Media" and browse to select the video file, or simply drag and drop the file (Mac only).
- Choose Audio Format: Next to "Choose Profile", select the desired audio format from the drop-down menu, such as "Audio – MP3" or "Audio – FLAC".
- Save as File: Click the "Save as File" button, then choose the destination folder, rename the file if needed, and hit Save.
- Start Extraction: Click Start to initiate the extraction process. The time it takes to extract the audio will depend on the file size. Once complete, the extracted audio will be saved in the chosen folder.
Alternative Methods
While VLC is a popular option, there are other tools and methods available for extracting audio from videos. These include online alternatives such as FlexClip, which offers a simple one-click extraction process, and Wondershare Repairit Video Repair, which can fix audio sync issues and extract audio from various file formats. Additionally, for audio CDs, Windows Media Player and Audacity are suggested as alternatives to VLC.

Converting audio formats
VLC Media Player is a free and open-source media player available on Mac and Windows. It is a versatile tool that can be used to extract audio from video files and also convert audio formats.
VLC can be used to convert audio formats, for example, from WMA to MP3. The process is similar to extracting audio from video files. Here is a step-by-step guide on how to convert audio formats using VLC:
- Open the VLC Media Player and click on "Media" or "File" (the exact wording may vary depending on your operating system).
- In the drop-down menu, select "Convert/Save" or "Convert/Stream".
- Click "Add" to browse and select the audio file you want to convert.
- Choose the output format from the drop-down menu near "Choose Profile". Options may include "Audio - MP3", "Audio - FLAC", or "Audio - (Vorbis) OGG".
- Click "Save as File" and then "Browse" to select the destination folder and rename the file if desired.

Fixing unsynced audio
VLC media player is a popular tool that works on a huge number of devices. However, there is a known issue with the software where audio and video can become unsynced. This can be incredibly annoying, especially if you can't work out a fix. If you wish to persist with the software, there are a few things you can try to fix the VLC player audio delay or mismatch.
Relaunch the app
A simple fix, but an effective one—simply close the VLC app and reopen it, then load the video you wish to watch again. There is a good chance that the video will play in sync.
Use hotkeys
Hotkeys are available to help people quickly shift the audio without having to go into complex settings menus. A couple of keys on the keyboard can tweak the audio to move it back or forward slightly. This is only a short-term fix for the VLC audio synchronization issues.
- Windows:
- If the audio plays before the visual, hit the 'K' key to slow down the audio.
- If you need to do the opposite, hit 'J' to speed up the audio.
- Mac:
- Use the 'G' and 'F' keys to adjust the audio.
Set Track Synchronization Value
This method will need to be applied separately for every video. Open “Window” on the Menu Bar and enter the desired audio delay in milliseconds. To make this process easier, adjust the delay using the hotkeys at first. Once it’s close enough, use the Track Synchronization dialog to make precise changes.
Set Audio desynchronization compensation
This is a permanent fix if there is some issue making the audio and video out of sync each time you load the app. Remember that you can use positive or negative values to move the audio and bring it backward or forwards as required. Continue to tweak until the video is absolutely perfect.
- Head to the Menu bar and choose “VLC > Preferences”.
- Locate the “Audio desynchronization compensation” option in the “Audio” sub-menu.
- Now you need to tweak the setting. Remember – you can use positive or negative values to move the audio and bring it backwards or forwards as required.

Using the VLC command line
VLC Media Player has a powerful ability to extract audio from video files. It can also be used to convert audio to different formats. The procedure for extracting audio from a video file using the VLC command line is as follows:
- Start VLC, then click on the "Media" button. In the drop-down menu, select "Convert/Save". Alternatively, you can press "Ctrl + R" on your keyboard to open "Open Media" directly.
- In the "Open Media" window, click on the "Add" button and select the video file from which you want to extract the audio.
- With the video file selected, click on the "Convert/Save" button at the bottom of the window.
- In the "Convert" window, choose the desired audio format or profile from the options provided. You can also adjust the audio settings, such as codec, bit rate, channels, sample rate, and volume, by clicking on the appropriate icons or menus.
- Specify the output path or destination folder for the extracted audio file.
- Finally, click on the appropriate button to begin the audio extraction and conversion process.
"c:\Program Files\VideoLAN\VLC\vlc.exe" -I dummy --no-sout-video --sout-audio --no-sout-rtp-sap --no-sout-standard-sap --ttl=1 --sout-keep --sout "#transcode{acodec=flac}:std{mux=raw,dst=C:\User\Admin\Desktop\yourAudio.flac}" Video.TS:///C:\User\Admin\Desktop\yourVideo.mp4\#0:01-3:38 vlc://quit
In this command, "C:\User\Admin\Desktop\yourAudio.wav" is the destination of the extracted audio file, and "C:\User\Admin\Desktop\yourVideo.mp4\#0:01-3:38" is the location of the original video file, followed by arbitrary starting and ending times.
It's important to note that VLC's graphical user interface (GUI) does not allow you to extract a single chapter or portion of a video file. To do that, you will need to use the VLC command line, which provides more flexibility in specifying the exact portion of the video you want to extract audio from.
Additionally, VLC offers advanced options for further customization. These options are in the form of {opt=val,opt2=val2}. For example, the FFmpeg audio/video decoder (avcodec) includes various audio and video decoders/encoders delivered by the FFmpeg library. You can also adjust the dynamic range compression with the "--a52-dynrng" option to make loud sounds softer and soft sounds louder, which is useful when listening in a noisy environment.
While VLC is a versatile tool, there are other dedicated audio extraction tools that may offer faster and more reliable performance for specific tasks.

Saving audio to a hard drive
VLC Media Player is a free, open-source media player that supports most audio and video formats, DVDs, CDs, and streaming protocols. It can be used to extract audio from video files and save it to a hard drive. The process is straightforward, although there are some slight differences between the Windows and Mac versions.
To save audio to a hard drive using VLC Media Player, first open the application. Then, click on "File" or "Media" in the top menu bar and select "Convert/Save" or "Convert/Stream". In the new window that opens, click "Open Media" and browse for the video file from which you want to extract the audio. Alternatively, you can simply drag and drop the video file into the VLC Player window.
Next, choose an audio format from the "Choose Profile" drop-down menu, such as "Audio – MP3", "Audio – FLAC", or "Audio – (Vorbis) OGG". Click "Save as File" and then "Browse" to select the destination folder on your hard drive where you want to save the extracted audio file. You can also rename the file as desired. Finally, click "Save" and the VLC Player will start extracting the audio from the video and saving it to your hard drive.
It's important to note that VLC Media Player currently only allows you to extract the full audio from a video, not a specific portion of the audio track. Additionally, the output format options are limited. For more advanced features and faster conversion speed, you may want to consider using alternative software, such as EaseFab Video Converter or FlexClip, especially if you are seeking ease of use and the best output quality.
