Why Extract Audio from MP4?

Many technical, creative, and practical reasons exist for extracting audio from an MP4 file. Here are some of the most common use cases for detaching audio from MP4:

1. Using Audio Files for Other Projects

MP4 files that contain commentary, interviews, or speech can be used to extract audio and repurpose it for voiceovers, audiobooks, or podcasts. On the other hand, if the video contains background music, you can extract it as MP3 and use it for personal projects, advertisements, or presentations.

2. Saving up on Storage Space

Audio files take less space in general. For example, AAC or MP3 files are compressed formats much smaller than MP4. If you want to store more audio content on your devices or in the cloud, it's generally a good idea to extract audio from MP4.

3. Creating Sound Effects or Ringtones

If a video contains exciting and unique sound effects, you can extract them and add them to different programs for further editing. You can also add them to other multimedia projects. The extracted audio files can also be used as ringtones or other phone notifications.

4. Audio Transcription

If you want to transcribe an MP4 file with presentations, lectures, or interviews, extracting audio first can make the process easier. Instead of adding videos to your speech-to-text tool, you can feed it with audio to generate a script more quickly.

5. Audio Sharing

Extracting audio from MP4 videos allows you to share the files more easily. For example, you can upload the audio to popular platforms like iTunes, Spotify, or SoundCloud for people to listen to. Since the audio files are smaller, it's easier to upload or share files with other people, including messaging apps that usually have limitations on file size.

Conclusion

These are the five best methods for extracting audio from MP4 files. These options can work perfectly fine if you just want to extract audio. However, suppose you want to get more creative with the audio files, add effects, perform edits, or incorporate them into your video editing workflow, we recommend using software like Wondershare Filmora. With AI-powered tools at your fingertips, video and audio editing has never been easier.
