Free Online Audio Visualizer
Drop in an MP3 or WAV, pick a spectrum, waveform or particle style, and export an MP4. Your file never leaves your browser.
Audio Visualizer Styles
The audio visualizer has six styles, all drawn from your audio as it plays: spectrum bars, a circle spectrum, a waveform line, particles, a pulsing cover and a spinning vinyl. Each has its own color, sensitivity and mirror settings. Tap a style to load it in the tool above.
How to Make an Audio Visualizer Video
- Add your audio. Drop in an MP3, WAV, M4A, OGG or FLAC file up to 10 minutes long. It is decoded on your device; nothing is uploaded.
- Pick a style and a shape. Choose one of the six styles, a color and the sensitivity, then 16:9 for YouTube, 9:16 for TikTok and Reels or 1:1 for a square post.
- Export the MP4. Choose 720p or 1080p and press Export. The whole song is analyzed first, so the video matches the preview and renders faster than real time; there is no watermark.
Spectrum vs Waveform: Which One Should You Use?
Use a spectrum when the song has a strong beat, and a waveform when the voice or a single instrument leads. A spectrum splits the sound into frequency bands, from deep bass on one side to cymbals on the other, so kicks and drops jump out as tall bars. That is why an audio spectrum visualizer suits electronic, hip-hop and pop tracks.
A waveform draws the shape of the sound over time as one moving line. It follows the voice closely and stays calm in quiet passages, which suits podcasts, acoustic songs and spoken word. If you are unsure, try both on the chorus: the one you can still watch after thirty seconds is the right one.
Use It as a Live Visualizer
Press Play and the visuals react in real time; press Full screen and the canvas fills the display. Switch the input to your microphone and it follows whatever is playing in the room, so it works as a live visualizer for a DJ set, a stream background or a party on a projector. Nothing is recorded or sent anywhere.
Want More Than Bars and Waves?
An audio visualizer draws shapes from sound. An AI music video goes further: it reads your song’s beat and sections and renders shots with people and places, cut on the beat. Try the AI music video generator with the same song; the first preview is free.
Making a Video for Your Own Release?
If you want your cover art and the song title in the frame, the music visualizer maker starts from a cover and a circle spectrum in vertical format, ready for TikTok and Reels.
Questions and answers
Is this audio visualizer free, and is there a watermark?
Yes, it is free and there is no watermark. You do not need an account, and there is no limit on how many videos you export. Everything runs in your browser, so it costs us almost nothing to offer, and we do not add a logo to your video.
Is my audio uploaded anywhere?
No. Your file never leaves your browser: it is decoded, drawn and encoded on your own device, and the finished MP4 is saved straight to your computer or phone. We cannot see or keep your audio. Only if you choose to make an AI music video afterwards is the song sent to us.
Which audio formats does it support?
It reads any format your browser can decode: MP3, WAV, M4A and AAC everywhere, and usually OGG, Opus and FLAC too. Files can be up to 10 minutes long. It exports MP4 (H.264 with AAC audio) where the browser supports it, and WebM otherwise.
Can I use it as a live visualizer with a microphone?
Yes. Switch the input to Microphone and allow access when the browser asks; the visuals then follow whatever the microphone hears, in real time and full screen. The microphone sound is only analyzed on your device, never recorded or uploaded.
How long can my audio be?
Up to 10 minutes per file. Longer recordings, like a full DJ set, can be split into parts in any audio editor first. Export speed depends on your device; on a recent laptop a three-minute song at 720p usually renders in well under a minute.
Can I export a vertical video for TikTok and Reels?
Yes. Choose 9:16 before you export and you get a vertical MP4 at 720p or 1080p, ready for TikTok, Instagram Reels and YouTube Shorts. 16:9 suits a normal YouTube video and 1:1 suits a square feed post.
Who makes this audio visualizer?
Oomvoo, an AI music video generator, offers this audio visualizer for free. Unlike the AI music video, which renders shots with characters and places and is paid by the second, the visualizer draws shapes from your sound in your browser and costs nothing. Use whichever suits the song.
