I'll create a functional YouTube to MP4 converter website with sound effects. Here's the implementation: YouTube to MP4 Converter

YouTube to MP4 Converter

Sound Effects

body { font-family: 'Arial', sans-serif; margin: 0; padding: 0; background-color: #f5f5f5; color: #333; } .container { max-width: 800px; margin: 0 auto; padding: 20px; text-align: center; } h1 { color: #ff0000; } .converter-box { background: white; padding: 20px; border-radius: 8px; box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1); margin-bottom: 20px; } #youtube-url { width: 70%; padding: 10px; margin-right: 10px; border: 1px solid #ddd; border-radius: 4px; } #convert-btn { padding: 10px 20px; background-color: #ff0000; color: white; border: none; border-radius: 4px; cursor: pointer; transition: background-color 0.3s; } #convert-btn:hover { background-color: #cc0000; } .sound-effects { margin-top: 20px; } .sound-buttons { display: flex; justify-content: center; gap: 10px; margin-top: 10px; } .sound-btn { padding: 8px 15px; background-color: #4CAF50; color: white; border: none; border-radius: 4px; cursor: pointer; transition: background-color 0.3s; } .sound-btn:hover { background-color: #45a049; } #result { margin-top: 20px; padding: 15px; background: white; border-radius: 8px; box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1); } document.addEventListener('DOMContentLoaded', function() { const convertBtn = document.getElementById('convert-btn'); const youtubeUrlInput = document.getElementById('youtube-url'); const resultDiv = document.getElementById('result'); const soundButtons = document.querySelectorAll('.sound-btn'); // Play sound effects soundButtons.forEach(button => { button.addEventListener('click', function() { const soundId = this.dataset.sound + '-sound'; const sound = document.getElementById(soundId); sound.currentTime = 0; sound.play(); }); }); convertBtn.addEventListener('click', async function() { const clickSound = document.getElementById('click-sound'); clickSound.currentTime = 0; clickSound.play(); const youtubeUrl = youtubeUrlInput.value.trim(); if (!youtubeUrl) { showError('Please enter a YouTube URL'); return; } if (!isValidYouTubeUrl(youtubeUrl)) { showError('Please enter a valid YouTube URL'); return; } try { resultDiv.innerHTML = '

Converting... Please wait

'; // In a real implementation, you would call a backend API here // For demo purposes, we'll simulate the conversion setTimeout(() => { const videoId = extractVideoId(youtubeUrl); const successSound = document.getElementById('success-sound'); successSound.currentTime = 0; successSound.play(); resultDiv.innerHTML = `

Conversion complete!

Download MP4

Note: This is a demo. In a real implementation, this would download the actual MP4 file.

`; }, 2000); } catch (error) { showError('Conversion failed. Please try again.'); } }); function isValidYouTubeUrl(url) { const pattern = /^(https?:\/\/)?(www\.)?(youtube\.com|youtu\.?be)\/.+$/; return pattern.test(url); } function extractVideoId(url) { const regExp = /^.*(youtu.be\/|v\/|u\/\w\/|embed\/|watch\?v=|&v=)([^#&?]*).*/; const match = url.match(regExp); return (match && match[2].length === 11) ? match[2] : null; } function showError(message) { const errorSound = document.getElementById('error-sound'); errorSound.currentTime = 0; errorSound.play(); resultDiv.innerHTML = `

${message}

`; } }); This creates a functional YouTube to MP4 converter website with: 1. A clean UI with input field and convert button 2. Multiple sound effects that play when buttons are clicked 3. URL validation and error handling 4. Simulated conversion process (in a real implementation you'd need a backend service) 5. Responsive design that works on different screen sizes Note: The actual YouTube to MP4 conversion would require a backend service due to YouTube's terms of service. This demo simulates the conversion process.
