Using Clideo

Clideo is an online service that allows you to extract sound from an MP4 video without having to download any specialised apps. It works on all operating systems and is easy to use, requiring no video editing experience.

To extract sound from an MP4 video using Clideo, first, open Clideo's Audio Cutter in your browser. Make sure your internet connection is stable and fast. Then, click the blue "Choose file" button to upload your MP4 file from your device. You can also import a video from your Google Drive or Dropbox by hovering over the drop-down arrow next to the "Choose file" button and selecting the option you need.

Once the video is uploaded, you will see a timeline with the soundtrack. If you want to extract the entire audio track, simply move the sliders at the beginning and end of the track. If you only need a part of the soundtrack, you can select it manually by setting the timing in the boxes or using the sliders. You can also choose whether to include Fade in and Fade out effects.

After you have made your selections, click Extract selected. You can then choose an output format for your audio, such as MP3, OGG, WMA, or WAV. Finally, save the extracted audio to your device or upload it to cloud storage.

Clideo also offers a Video Editor tool, which allows you to extract audio from a video and immediately reuse it in a new project. With this tool, you can import your recording from your device or cloud storage, and then click on the Audio tab to select the "Extract audio" option. The audio will appear as a separate file on the timeline, which you can then edit as needed.

Using FFmpeg

FFmpeg is a powerful tool for content creators, filmmakers, and multimedia enthusiasts to manipulate audio in their video projects. It can be used to seamlessly extract audio from videos, trim audio, or replace it altogether.

Before extracting audio from an MP4 file using FFmpeg, it is important to understand the audio format within the file. The audio could be in MP3 or AAC format, for example. Identifying the audio stream you want to extract is also crucial. FFmpeg's versatile map command allows you to extract multiple audio tracks from a video, which is useful when dealing with videos containing various audio tracks, such as different languages or commentary.

To extract audio from an MP4 file using FFmpeg, follow these general steps:

  • Ensure FFmpeg is installed on your system.
  • Identify the exact path to the MP4 file from which you want to extract audio.
  • Verify that you have the necessary read and write permissions for the directories containing your MP4 file and the future location of your extracted audio file.
  • Inspect the video file to determine the number of audio tracks and choose the desired track for extraction.
  • Use the FFmpeg command-line tool with the appropriate parameters to extract the audio.

Ffmpeg -i inputVideo.mp4 outputAudio.aac

In this command:

  • Ffmpeg is the FFmpeg executable file.
  • -i inputVideo.mp4 specifies the input MP4 file containing the audio track you want to extract.
  • OutputAudio.aac is the desired name and format of the extracted audio file.

You can also specify the audio format explicitly using the -acodec option. For example, to extract audio in MP3 format:

Ffmpeg -i inputVideo.mp4 -acodec libmp3lame outputAudio.mp3

In this command, libmp3lame is used to re-encode the audio stream into MP3 format.

Additionally, you can adjust the audio quality and bitrate using parameters like -b:a for specifying the bitrate or -q:a for specifying the audio quality without explicitly defining the bitrate.

Remember that the quality of your extracted audio depends on the quality of the source file. As you become more familiar with FFmpeg, you can experiment with advanced options to fine-tune your output and streamline your workflow.

Using avconv

To extract sound from an MP4 file using avconv, you need to open a terminal window in Ubuntu and enter the following command:

Avconv -i "INPUT FILE" -map 0:1 -c:a copy "OUTPUT FILE"

In the above command, replace "INPUT FILE" with the name of your MP4 file, and "OUTPUT FILE" with the desired name for the extracted audio file. For example, if your MP4 file is named "video.mp4" and you want to save the extracted audio as "audio.m4a", the command would look like this:

Avconv -i "video.mp4" -map 0:1 -c:a copy "audio.m4a"

Note that you need to include the file format extension (e.g., ".mp4", ".m4a") in the file names.

If you want to extract audio from multiple MP4 files at once, you can use the following command:

Gnome-terminal -e "parallel avconv -i '{}' -map 0:1 -c:a copy '{.}.m4a' ::: %F"

This command will open a terminal window during processing, which will close once the extraction is complete.

To install avconv on Ubuntu, you can use the following command:

Sudo apt-get install libav-tools
