FFT Spectrogram Music Player vs Spek Spectrogram analyzer

The FFT Spectrogram Music Player is not just a regular audio player, but a powerful tool for the perfectly synchronized and fascinating visualization of sound in real-time. I originally created this app for myself because I love "watching" the music I am listening to. Visualizations reveal so many hidden details in a track, whether it's the vocals, drums, or intricate melodies. I invested a lot of time ensuring the audio and visuals are perfectly in sync. When playing over Bluetooth, you can easily adjust the audio timing in the settings to maintain this perfect synchronization (for reference, I use -250ms when playing directly on my iPhone, and about +100ms for my car stereo). While my personal favorite is the 2D waterfall spectrogram, I have also added stunning, interactive 3D visualizations to offer even more variety. You can fully control the camera using touch gestures—just play around and explore! If you are missing a feature or have any feedback or wishes, feel free to drop me an email. Whether you are an audiophile, a musician, or just a fan of breathtaking visual effects – this app precisely analyzes the frequencies of your music and displays them seamlessly. Main Features: • Spectrum Analyzer: High-resolution stereo display (Left/Right) with 512 frequency bands for detailed frequency analysis. • Waterfall Chart: Track the acoustic history of the last 3.0 seconds in a breathtaking, color-coded waterfall graph. • 3D visualizations, customizable with drag and pinch gestures (with one finger: drag - and two fingers: rotate - Mac: click/drag: move camera left/right/up/down; shift and click: rotate, pinch to zoom) • Real-Time Sync: The visualizations react to the beat and frequencies of the music without any noticeable lag. • Built-in Player & Playlists: Manage and play your favorite music directly within the app. • Microphone Input: Use your iPhone's microphone to visualize ambient sounds, live music, or your own voice in real-time. Free Version & Pro Upgrade: You can download and try the FFT Spectogram Music Player for free. Please note that the diagrams in the free version feature a subtle watermark. Love the app? Unlock the Pro version with a one-time in-app purchase for just $0.99 (0,99 €)! The upgrade permanently removes all watermarks, allowing you to enjoy the pure, unclouded visualization of your music.
