FrequencyCat vs DashJam

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.

DashJam quietly records your whole rehearsal so you never lose the moment you forgot to hit record for. Start a session and keep playing. DashJam holds the most recent 15 minutes of audio in a rolling buffer. When something good happens — a riff, a take, a happy accident — tap Save Jam and pick exactly the stretch you want right on the live waveform. The moment lands in your Library as a shareable audio file. No more "wait, were we recording?" WHY MUSICIANS LIKE IT • Record continuously, decide later. The last 15 minutes are always there to save — you choose the moment after it happens, not before. • Pick it on the waveform. Save Jam opens a live waveform; drag the handles to grab just the part that mattered, then confirm. • Save from the Lock Screen. A Live Activity and Dynamic Island show the recording state and put a save action a tap away while your phone is in your pocket or on a stand. • It survives a crash. If the app gets killed mid-session, your rolling buffer is still there when you reopen. • A Library you'll actually browse. Saves get evocative auto-generated names ("Crimson Spiral", "Velvet Comet") you can rename, with in-app playback. • Your files, your way. Saved jams export as .m4a and show up in the Files app under DashJam — share them by AirDrop, Messages, or any share sheet. • Designed for iOS. Clean, content-first interface built on the latest iOS design system, tinted recording-red. • English and German, with an in-app language override. PRIVATE BY DESIGN Audio never leaves your device. The rolling buffer lives in the app's cache; saved jams live in the app's documents folder. Nothing is uploaded, ever — you decide if and when a recording leaves your iPhone by sharing or exporting it. There are no accounts, no sign-in, and no tracking. DashJam needs microphone access to record, and keeps recording in the background so a session keeps running while you play. That's it. DASHJAM PRO — OPTIONAL Everything above is free. DashJam Pro unlocks a rolling buffer of up to 60 minutes, automatic jam detection (Beta), trimming saved jams on the waveform — keeping the original or replacing it — Places (arrival and leave reminders at your rehearsal spots), and the audio quality/mono picker. • DashJam Pro — Yearly: 1-year auto-renewing subscription • DashJam Pro — Monthly: 1-month auto-renewing subscription • DashJam Pro — Lifetime: one-time purchase, does not renew Prices are shown in your local currency inside the app, on the DashJam Pro screen, before you buy.
