An audio visualizer made for YouTube
Uploading a song with a static picture loses viewers in seconds. A reactive visualizer keeps them watching: your cover, your title and a scene that moves with the music, exported as a crisp 16:9 MP4 up to 4K.

How it works
- 1
Drop in your track
MP3, WAV, FLAC or M4A. The file never leaves your computer — nothing is uploaded.
- 2
Pick a look
Choose from 80+ reactive templates, set colours, cover art, text and effects. You see the result live.
- 3
Export the video
MP4 up to 4K, rendered faster than real time — for YouTube, Shorts, TikTok, Reels or Instagram.
What you get
16:9 up to 4K
Sharp on big screens; 1080p and 1440p export in a fraction of the track's length on most computers.
Cover art and title
Your artwork in the centre or as the background, with the track and artist name in your font.
Timer overlay
An optional running clock or countdown, the way music channels like it.
Shorts from the same project
Export the vertical version too, or let PulSound pick the best 30 seconds for a Short.
Questions
What resolution should I use for YouTube?
1080p is the standard; 1440p or 4K looks noticeably sharper and gets YouTube's higher-quality encoding. All of them are free in PulSound.
Who owns the video?
You do. The video is made on your device from your music; use it anywhere, including monetized YouTube channels.
Do you upload my track?
No. Your audio, images and the finished video never leave your computer — everything is rendered in your browser. There is nothing to install either.
Which browser should I use?
A current Chrome, Edge or Safari on a computer gives the fastest export (usually faster than real time). Firefox and phones work too, at real-time speed.
