What are the limits of Audio Visualizer Maker?
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. Artwork: one JPG, PNG or WebP up to 30 MB, reduced to 4 MP. Waveforms and frequency bars are measured from the selected audio; the static layout preview does not simulate the animation. Artwork and title are rasterized into the exported video.
