Final answer:
Extracting audio from a video on an iPhone requires a third-party app like 'iMovie' or 'Audio Extractor'. You can detach and export the audio using iMovie or use a different app that may have more direct methods.
Step-by-step explanation:
To extract audio from a video on an iPhone, you'll need to use a third-party app since iOS does not have a built-in feature for this task. There are several apps available on the App Store that can accomplish this, such as 'iMovie' or 'Audio Extractor'. Here's a general method using iMovie:
- Open 'iMovie' and create a new project, then select the video file from which you want to extract the audio.
- In the project, tap the video on the timeline to select it, then tap the 'Detach Audio' option. This will separate the audio track from the video.
- Once the audio is detached, delete the video track. Now, you have only the audio left in the project.
- Share or save the project, and choose 'Audio Only' to export the extracted audio file.
Note that steps might vary slightly depending on the app used. Also, other popular third-party apps may have more straightforward methods for extracting audio directly. Whichever app you choose, follow the app-specific instructions for extracting audio.
