About
Make a free online audio visualizer video from a song, podcast or voice track. Load an MP3, WAV, M4A, OGG or AAC file, choose 16:9 for YouTube, 9:16 for Shorts and Reels, or 1:1 for a square post, and export an MP4 file in which the bars move with the sound.
Under Theme, the preview offers Spectrum Bars, Circular Wave and Oscilloscope. Press Play & Animate to watch the preview react to the audio as it plays. The exported video always uses the Spectrum Bars style, so the other two styles appear only in the preview.
The video is rendered on your device and is not uploaded. A longer track takes longer to render, and a progress bar shows how far the export has got. The export does not add a watermark.
