Questions
Is it really free?
Yes. Make and download as many videos as you like, up to 4K. A small PulSound mark appears for a few seconds at the start and end of the video.
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.
What is a music visualizer?
A video whose graphics move with the sound — bars, rings or particles driven by the frequencies and beats of the track. It turns an audio-only release into something people watch.
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.
