Turn any audio file into an animated visualizer video — a clean waveform, reactive musical bars, or a colorful spectrum, all synced to the sound — exported in 9:16, 1:1, or 16:9 from the free ViralMint desktop app.
Waveform (a colored line that pulses with the amplitude on a palette background), Musical bars (a constant-Q transform that reacts to the actual notes), and Spectrum (a scrolling frequency spectrogram). All three are rendered frame-accurate to your audio so the motion always matches the sound.
Promote a track on Reels, post a podcast audiogram to Shorts, or turn a voice memo into a shareable square video. Four color palettes (Sunset, Ocean, Neon, Mono) and three aspect ratios cover every platform without opening an editor.
No subscription and no export caps. The visualizer is rendered entirely with FFmpeg on your own machine — your audio never leaves your computer — for a flat fee of about $0.03 per video, with no watermark on the output.
Launch the free ViralMint desktop app and open the Music Visualizer tool from the Tools page.
Drop in an MP3, WAV, M4A, or other audio file — a song, a podcast segment, or a voice memo.
Choose Waveform, Musical bars, or Spectrum; a color palette; and 9:16, 1:1, or 16:9 for your target platform.
Click Generate. ViralMint renders the animation synced to your audio and exports a ready-to-post MP4 with the sound muxed in.

MP3, WAV, M4A, AAC, OGG, and FLAC. Upload a song, a podcast segment, or a voice memo — the visualizer reacts to whatever audio you give it.
Waveform draws a colored line that pulses with the loudness over a palette background — clean and brand-friendly. Musical bars use a constant-Q transform that reacts to the actual musical notes — best for songs. Spectrum is a scrolling frequency spectrogram — a techy, full-frame look. All three stay frame-accurate to the audio.
Yes — that's a core use case. Drop in a podcast clip, pick 1:1 or 9:16, and you get a shareable audiogram that visualizes the talking so a silent-autoplay feed still stops the scroll.
About $0.03 per video, flat, with no subscription, no watermark, and no export caps. The render runs locally with FFmpeg so there's no cloud-processing surcharge.
1080-wide for every aspect ratio — 1080×1920 for 9:16, 1080×1080 for 1:1, and 1920×1080 for 16:9 — encoded as H.264 MP4 with your original audio muxed in.
The Music Visualizer ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
