Free Audio Spectrum Maker and Music Visualizer
Vimitron's free audio spectrum maker turns a song into a music visualizer video you can post on YouTube, Instagram Reels or TikTok. Choose from 18 spectrum styles, six of them 3D (globe, terrain, pillars, skyline, tunnel, orb), plus the NCS-style circle, bars, capsules, radial waves and particles. Pick your own colours, add a cover image and background, trim the song, and add synced karaoke lyrics, written by hand or generated automatically. Add your song on this page, then open it in the studio with a free account. The video has no watermark, and your song is processed in your browser.
How to make an audio spectrum video: add your MP3, WAV or M4A song on this page, press Open in studio, choose a spectrum style and colours, add a title and optional lyrics, drag the timeline handles to pick the part of the song you want, then press Download video.
The preview runs live in your browser from the song's real frequencies, so the bars, circle or 3D shape move with the bass and treble. When you download, every frame is drawn at its exact time and saved as a standard MP4 at up to 1080p and 60 frames per second, so the result is smooth on any computer and does not have to wait for the song to play through.
Free audio spectrum maker features: 18 visualizer styles, custom colour stops with percentages, shape controls (size, rotation, thickness, glow), cover image, background image, lyric X/Y position, karaoke colours, 16:9, 9:16 and 1:1 sizes, and an .lrc lyrics export.
Frequently asked questions
What is an audio spectrum maker?
An audio spectrum maker turns a sound file into a video where bars, circles, waves or 3D shapes move with the music. It reads the frequencies of the song as it plays and draws them frame by frame, so the visuals follow the bass, the vocals and the highs.
Is this audio spectrum maker free?
Yes. The Vimitron Spectrum tool is free to use. You can watch a live demo on the page, and a free account opens the studio where you load your song, try every style and colour, and download the video.
Does the video have a watermark?
No. Vimitron does not add a watermark, logo or branding to the video you download.
Is my song uploaded to a server?
No. The song is decoded and drawn inside your browser, and the video is recorded there too. The only exception is the optional automatic lyrics feature, which sends the audio to our service to be transcribed and deletes it straight after.
How do I make an NCS-style visualizer?
Choose the NCS Circle style, add your cover image so it appears in the middle of the circle, pick a colour palette, then trim the song and download the video. You can change the circle size, bar thickness, rotation and glow.
Which audio files and video sizes are supported?
MP3, WAV, M4A, AAC, OGG, FLAC and Opus files that your browser can play. You can make 16:9 videos for YouTube, 9:16 for Reels, Shorts and TikTok, and 1:1 for feeds. The video is saved as MP4 or WebM, depending on your browser.
Can I add lyrics to the visualizer?
Yes. Type or paste the lyrics and tap to time each line, import an .lrc file, or let the tool generate timed lyrics from the song automatically (sign-in required, and singing is transcribed less accurately than speech, so check the text). Karaoke mode fills each line as it is sung, and you can choose its colours and position.
How long does it take to download the video?
In browsers that can encode MP4 (such as current Chrome and Edge), each frame is drawn and encoded as fast as your computer allows, so the time depends on your computer, the style and the video size, not on the length of the song. Keep the tab open while it renders; the file then downloads by itself. In other browsers the video is recorded while the song plays, so a three-minute selection takes about three minutes.
What is the difference between a spectrum visualizer and a waveform?
A spectrum shows how loud each pitch range is at each moment, from bass on one side to treble on the other, so bars and rings react to different parts of the music. A waveform shows the overall loudness of the sound over time as a single line. This tool draws both: bars, circles, dots and 3D shapes follow the spectrum, while Oscilloscope and Radial Wave draw the waveform.
What video size should a music visualizer be for YouTube, Shorts and Reels?
Use 16:9 (1920x1080) for YouTube, 9:16 (1080x1920) for YouTube Shorts, Instagram Reels and TikTok, and 1:1 (1080x1080) for feed posts. You can switch between them and between 1080p and 720p without losing your style or colours.
Can I turn an MP3 into a video with a visualizer and my own image?
Yes. Add the MP3, choose a style, then add a cover image, a background image or both. With the NCS Circle style the cover sits in the middle of the circle and pulses with the bass. You can also add a title and lyrics, and then download the result as a video.
Which spectrum style works best for my song?
For a song release, NCS Circle with your cover art is the usual choice. For ambient, lo-fi and chill tracks, Soft Wave, 3D Terrain or Oscilloscope suit slower music. For electronic and bass-heavy tracks, Pulse Rings, Tunnel, Particles and LED Equalizer move more with the beat. For podcasts and speech, Oscilloscope and Radial Wave stay readable.
