💡 Design Tips for Better Waves
• **Circular Waveforms:** Place cover art in the center to build a classic podcast/vinyl visualizer effect.
• **Local Rendering:** Video compilation takes place entirely inside browser memory using the native MediaRecorder API. No data is sent to external clouds.
• **Audio Synchronization:** Click "Preview Audio" to start analyzing frequencies before hitting "Render".
Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
How does the in-browser video renderer work?
We use the Web Audio API to decode and analyze the frequency spectrum of your audio track, render the waveform frames onto a canvas in real-time, and record the combined audio/video stream using the browser's native MediaRecorder API.
Why is the exported video in .webm format?
The WebM format is natively supported by modern browsers for real-time canvas capture. You can upload WebM files directly to social platforms or convert them to MP4 using standard local converters if needed.
