Hide Any Image In Sound

A spectrogram is a visual representation of sound frequencies. Spectrogram art hides an image inside an audio file - when you open the audio in a viewer like Audacity or Spek, your picture appears. Made famous by Aphex Twin's hidden face in "Windowlicker" and the pentagram in DOOM's soundtrack.

Upload any image or type text. Our engine converts it into audio frequencies using advanced audio processing - placing your image precisely within the sound spectrum. Download the WAV file and view it in any spectrogram analyzer.

Subscription credits give you one precision-crafted WAV file per credit at your chosen frequency range and duration. Each conversion generates 10 WAV files - one for each frequency band from sub-bass to ultrasonic - plus a FullSpectrum file. Start with 10 free credits, then choose a subscription plan. All files are lossless WAV, ready for commercial use.

Any image up to 10 MB. High-contrast images - logos, text, silhouettes, line art - produce the most striking results. Photos work too, but bold graphics really pop in the spectrogram.
