FrequencyCat vs MIDI Scribe

Hide an image inside sound. FrequencyCat is a playful tool for exploring the connection between images, sound, and spectrograms. Choose an image, and FrequencyCat transforms it into a unique audio signal. Play the sound and view its spectrogram, and you’ll see the original image emerge again from the frequencies. 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.

MIDI Scribe is a free productivity app for capturing and organizing practice takes from your MIDI-capable musical instrument. Run it while you practice, and it will automatically start new takes after every session break, with a configurable auto-take idle time, as well as support for specific MIDI commands (such as a middle or left piano pedal press) to manually start and end takes. A piano roll is provided to review and scrub individual takes. Star the takes that you want to keep indefinitely, while unstarred takes are cleaned up over time based on a configurable retention policy. All takes can be exported as MIDI files for use in other programs. MIDI Scribe is completely private. Connect your instrument, capture your takes, and keep everything securely on your device . No ads, no analytics, no snooping on your usage, and nothing ever leaves your device unless you export it. MIDI Scribe is completely free and open source for you to enjoy.
