Frequently Asked Questions
How do I record a video of my visualization?
Click "Start Recording" to begin — the audio plays automatically while the canvas is captured. Click "Stop" to end the recording, or let it finish on its own. Once done, a download button will appear to save your video.
What audio formats are supported?
The visualizer accepts MP3, WAV, OGG, and FLAC audio files up to 100 MB. All processing — waveform rendering, genre detection, and video recording — happens locally in your browser. Nothing is sent to any server.
Is my audio file uploaded to any server?
No. All processing happens locally in your browser. Your file never leaves your device.
What format is the exported video?
Videos are exported as WebM. Most modern browsers and video editors support this format. If you need MP4, you can convert the file with any standard video converter.
What is the Shorts Generator?
The Shorts Generator splits your exported video into vertical clips (e.g. 1080×1920 for YouTube Shorts). You can choose the resolution, clip length, and number of clips. All processing happens in your browser.
Why does the canvas show an animation before I upload?
The visualizer runs a demo animation to let you preview and configure your layers before committing to a file. Once you upload audio, the visualization reacts to your track in real time.
