GIVE YOUR SOUND A SHAPE
Turn your song into a video that moves with the sound. Choose a waveform or spectrum, make it yours and export the complete track for free.
Use audio and artwork you have permission to use. Your local files are not uploaded.
A color background is included. Covers stay local; this tool does not generate new AI images.
Your song sets the motion.

Leaving this page clears the audio, artwork and video. Download anything you want to keep.
Choose a music file from your device, or sign in and select one of your available RapDuo songs. Pick a visual style, set the video shape and choose an accent color. You can add a song title, artist name and your own cover image. Press play to check the motion, then export and download the video. The waveform and spectrum are driven by your actual audio, so a quiet passage and a loud chorus look different.
A sound wave follows changes in the audio signal, while spectrum bars show the energy across frequency bands. The radial spectrum arranges those bands around a circle. Use the line for a clean recording or podcast, the bars for a beat-led track, and the circle for an album-style visual. All three use the same original audio. Adjust the accent color and cover to match your release without changing the sound or generating another song.
Landscape 16:9 works for a widescreen music upload, portrait 9:16 suits a vertical post, and square 1:1 makes an album-style clip. The longer edge is 1280 pixels in landscape and portrait; square videos are 720 by 720. This is a continuous animation rendered for the length of your song, up to six minutes. It does not rely on a short AI video model or stitch together unrelated generated scenes.
Your browser analyzes the audio and records the canvas animation with a soundtrack. Local music and artwork are not uploaded to RapDuo, and the export uses no generation credits. MP4 is offered when your browser supports recording that format; other supported browsers export WebM. Recording runs in real time, so a four-minute song takes about four minutes to export. Keep the tab visible and your device awake, then download the result before leaving the page.
If you already made a song on RapDuo, use the visualizer action on its result card to bring that exact version into this tool. Only the song’s owner can load the private audio, and expired results stay unavailable. The song is not regenerated or charged again. A visualizer is useful when you want a complete soundtrack with a simple moving cover; choose the separate lyric video generator when you want the words timed on screen.
Yes. Local previews, the three visual styles, cover customization and full-song video downloads are free and have no watermark. You do not need an account for local files. RapDuo’s separate AI music, cover and portrait video generators have their own credit prices.
Choose MP3, WAV, M4A, AAC, OGG, FLAC or WebM audio up to 60 MB and six minutes. The file must use a codec your browser can decode and contain mono or stereo audio. MP3 and WAV are good starting formats. Try a shorter file if your device has limited memory.
Yes. The waveform reads the audio signal and the spectrum styles read its frequency energy during playback and export. This is different from a decorative animation that keeps moving without a song. Pause playback and the preview stops; the finished video includes the original song.
MP4 with audio is available in browsers that support MP4 recording. The tool detects support before export and shows the format you will receive. If MP4 recording is not available, it offers WebM instead. Format and encoding support can differ between browsers and devices.
The browser records the animation and audio while the song plays. A five-minute track therefore needs approximately five minutes, plus a brief finalization step. Switching tabs or locking the device can interrupt recording, so a hidden tab cancels the export instead of delivering a silent or incomplete video.
You can choose audio, customize the design and preview on a current mobile browser. Successful recording depends on its format support, memory and ability to keep the page active. Start with a short clip to check the result. A desktop browser is preferable for long songs or large files.
Local music, cover images and exported video stay in this browser session. Selecting My music downloads your own available RapDuo audio through its authenticated access route. The tool does not upload that audio again or create a server rendering task. Download your work before closing the page.
