Create colourful waveform and spectrum videos with gradient styles and photo backgrounds.
Use the guide alongside the working tool.
Open Audio Visualizer Maker →Prepare
Add an audio file and select up to 10 minutes.
Adjust and review
Choose one of six signal styles and eight gradient palettes. Add a full-frame photo background, adjust its crop, blur and contrast. Place the signal with presets, sliders or dragging; add album art, title and subtitle.
Save your result
Render a short sample or the full MP4, watch the actual animation and download.
Limits and compatibility
Files are processed on your device and are not uploaded. Use a current browser; memory-constrained devices may need smaller inputs. Cancellation stops processing. Originals remain unchanged. The pinned FFmpeg WebAssembly engine downloads about 31 MB from jsDelivr on first use. Video encoding can take several minutes on mobile. MP4 uses H.264/AAC and strips source metadata. Inputs are capped at 100 MB combined and 10 minutes per media file. DRM media is unsupported. Output is limited to 10 minutes at 24 fps and up to 1080p. Background: one JPG, PNG or WebP up to 20 MB, normalized to 4 MP / 2400 pixels. Six measured styles include thread wave, spectrum, mirror, equalizer, particles and ribbon, with eight gradient collections. Waveform styles measure amplitude; spectrum styles measure frequency energy. Visual sensitivity does not change exported audio volume. Signal position and opacity are encoded into the video. Optional album art/logo is separate from the background photo, within the same 100 MB combined limit. Touch dragging is available in expanded mode; inline touch scrolling is preserved. Rendering progress uses encoded time divided by selected output duration, followed by finalization; preparation is indeterminate and no remaining-time estimate is claimed. The initial canvas is a labelled layout illustration, not an analysis of your file; render the 8-second sample to review actual animation. Background, gradient layers and title are rasterized into the video. Canvas blur support depends on your browser.
