With FrequencyCat, you can: - Turn images into sound - View audio spectrograms in real time - Play sounds and reveal the images hidden inside them - Explore how different images create different sounds - Discover the relationship between sound, frequency, and Fourier transforms in an intuitive way There’s no magic behind it. Just frequencies, phases, an inverse Fourier transform, and a little curiosity about sound. Whether you’re interested in acoustics, music, signal processing, or simply wondering what an image might sound like, FrequencyCat gives you a new way to explore. Pick an image. Hear what it sounds like.

See your voice as a graph, hear it as piano. Vocal to Piano displays the pitch of your recorded voice as a real-time graph, then analyzes it and turns it into piano sound.

A yellow curve traces your pitch over time, and orange blocks highlight sections where your pitch stayed steady. You can freely scroll the graph up, down, left, and right. Save and Load Recordings Use Save in the settings menu to keep your favorite recordings, and Load to bring back any recording you've saved before. Customize the Graph Your Way Adjust volume sensitivity to reduce background noise. Freely resize the graph's height and horizontal spacing. Choose how pitch is displayed: curve, blocks, or dots. Choose how note names are shown: C4, Do 4, or MIDI number.
