Social networks do not accept audio files, and a still picture over sound gets scrolled past. A waveform that moves with the music shows at a glance that something is playing.
Choose a line, a filled wave, spectrum bars or a stereo scope, set its color and place it on a plain background or on your cover picture. Sizes cover YouTube, square feed posts and vertical Reels and Shorts.
How to use the Audio Visualizer Video Maker tool
- Add the audio file.
- Choose the look, the colors, the size and an optional background picture.
- Start, wait for the video to be drawn, and download the MP4.
Popular uses
- Podcast clips and audiograms
- Posting a song or a beat to Instagram, TikTok or YouTube
- Voice notes that need to be a video
Tips for the best result
- Trim the audio to the best 30 to 60 seconds first; shorter clips are drawn much faster.
- Dark backgrounds with one bright wave color read best on a phone.
