Command Line Spectrogram

Sometimes you don’t want a DAW. You want a damned picture.

This tool eats a WAV or MP3 file and spits out a grayscale spectrogram. No GUI. No timeline scrubbing. No fancy overlays. Just the frequencies plotted over time so you can see the noise that’s hiding inside.

Perfect for checking RF captures, voice channel recordings, or any weird sound dump from a SIGINT op gone sideways.

It's quiet. It’s fast. And it works every time.
