Okay, I need to write an article about how to extract audio from video. Let me start by understanding the user's requirements. The keyword is "How To Extract Audio From Video," and they provided some context phrases like "Learn," "Here is a quick guide/tutorial on," and "In this tutorial, we'll guide you through the process of." The article needs to be 600-900 words, use natural headings, avoid unsupported claims, and not mention AI. First, I should outline the structure. Maybe start with an introduction explaining why someone would want to extract audio from a video. Then list the methods. The user mentioned three context phrases, so perhaps three main methods with subpoints. Let me think of common tools: online converters, desktop software like VLC, and maybe mobile apps. Also, maybe command-line tools for more advanced users. Wait, the user wants natural headings. So maybe h2 and h3 tags. Let me plan the sections. Introduction, then three main methods each as h2, with their steps as h3 or just paragraphs. Let me check the example response they provided. Oh, in the example, they used h2 for each method and h3 for steps. So I should follow that structure. I need to make sure each method is explained clearly. For online tools, mention popular ones like Online-Convert or CloudConvert. For desktop, VLC is a common one. For mobile, maybe apps like Video to MP3 Converter. Also, command-line tools like FFmpeg might be useful for advanced users. I should avoid unsupported claims, so stick to what's generally known. For example, not all tools support every format, so maybe mention that. Also, note that free tools might have limitations like watermarks or file size limits. Let me start drafting the introduction. Something like: "Extracting audio from video files is a common task for content creators, podcasters, or anyone needing to repurpose media..." Then explain the purpose. Next, the three methods. Let's go with online converters, desktop software, and mobile apps. Each as an h2. Under each, a brief description and steps using h3. For example, under online tools: "Using Online Converters," then steps like upload, select format, convert. Wait, the example used "Here is a quick guide..." so maybe start each section with that phrase. Also, the user provided "In this tutorial, we'll guide you through..." so maybe in the intro, mention that the tutorial will cover these methods. I need to make sure the word count is met. Each section should be around 200-300 words. Let me outline each part: 1. Introduction (100-150 words) 2. Online Converters (200-250 words) 3. Desktop Software (VLC) (200-250 words) 4. Mobile Apps (200-250 words) 5. Conclusion (100 words) That should total around 800-900 words. Let me check the example response again for structure. The example had three methods, each with h2 and steps as h3. The conclusion wasn't present in the example, but the user didn't mention it, so maybe include a brief one. Also, the user wants natural headings, so avoid anything too technical. Use terms that are accessible. For example, "Using Free Online Converters" as an h2, then steps like "Step 1: Choose a Reliable Converter." I need to ensure that each method is explained step-by-step. For VLC, steps like open the video, go to convert/save, select audio output, etc. For mobile apps, maybe download an app, import video, convert, save. Potential issues: Some methods might not work on all devices or operating systems. Need to mention that. Also, file formats: MP3 is common, but others like WAV or AAC might be options. Mention selecting the right format. Avoid unsupported claims: Don't say a tool is the best, just present options. For example, "Popular online converters include..." instead of "The best online converter is..." Also, include tips like checking the output quality, file size limits, and ensuring the source video has the audio track. Maybe a note about
