A client-side tool that extracts a frequency spectrum from any position in a WAV file and exports it as a clean SVG vector path.

Drag and drop a .wav file, adjust the analysis position and time window, choose your resolution and compensation, and download a ready-to-use .svg spectrum. The frequency axis spans 40 Hz to 40 kHz on a logarithmic scale, with optional auto-bezier smoothing and spectral tilt compensation. All processing happens locally via a built-in PCM WAV parser (8/16/24/32-bit). Nothing leaves your machine.

The generated SVG plots dB amplitude against frequency on a log scale, making it ideal for visualising the tonal balance of any audio sample — from kick drums to full mixes. The compensation slider removes the natural spectral slope, and the curve toggle switches between straight segments and Catmull-Rom smooth interpolation.
