Smaller files
MP3 is easier to move and usually uses less memory than an uncompressed WAV of the same duration.
Fast, compact, broadly compatible
Visualize an MP3 in your browser.
Check the file's basic details locally, then open it in the audio visualizer to create bars, waves, or a radial spectrum.

Why MP3
When MP3 is the practical choice
MP3 trades some source detail for a much smaller file, which is often useful in a browser workflow.
Broad support
Modern desktop and mobile browsers generally decode MP3 reliably, making it a sensible first format to try.
Good visual response
A well-encoded MP3 still provides useful frequency information for bars, waves, and radial animations.
Know the tradeoff
MP3 versus WAV for visualization
The visual difference may be small, but the workflow difference can be substantial.
| Consideration | MP3 | WAV |
|---|---|---|
| File size | Usually much smaller | Usually much larger |
| Audio data | Lossy compression | Typically uncompressed PCM |
| Browser workflow | Fast and practical | Best with enough memory |
| Use when | Convenience matters | You already have a master |
Your MP3 is ready for motion.
Open the visualizer and create a reactive composition without uploading the track.
