Visualize audio spectrum and waveform locally in your browser. This tool helps artists, producers, audio engineers and labels quickly inspect frequency content and waveform movement before distribution, mastering review or catalog checks.

This tool provides a visual approximation of audio frequency content and does not replace professional mastering analysis tools. Version 1 is visualization only: it does not modify, export, normalize or master the file.
