The v1.1 update delivers up to 3x lower CPU usage for smoother spectrogram rendering, ensuring responsive displays even in demanding AUv3 hosts. It also updates the underlying framework for better stability and resolves audio pass-through issues, allowing the signal to flow correctly through plugins without interruption.
Key changes in v1.1 include:
- Up to 3x lower CPU usage for fluid, high-performance spectrogram visualization
- Updated framework for enhanced compatibility and overall stability
- Fixed audio pass-through in AU and AUv3 hosts for seamless signal routing
FFT AUv3 Visualizer is a compact, real-time spectral analyzer that leverages a 4096-sample FFT engine with Blackman-Harris windowing to map frequencies on a mel scale, providing clear insights into audio signals for mixing, mastering, and sound design on iPhone and iPad.
With a 90dB dynamic range and intelligent color mapping—from deep blues for sub-bass to warm reds for highs—the app excels in acoustic analysis and live monitoring. Its resizable interface adapts to various screen sizes, supporting standalone use or integration as an AUv3 plugin in apps like AUM or GarageBand, making it a lightweight essential for mobile producers seeking precise frequency visualization without excess CPU drain.
Key features include:
- Real-time 60Hz FFT analysis with 75% overlap for detailed frequency mapping
- Mel-scale frequency display with 90dB dynamic range and intelligent color gradients
- Blackman-Harris windowing to minimize spectral leakage
- Resizable, touch-optimized interface for iPhone and iPad
- AUv3 plugin compatibility for seamless DAW integration
- Low-latency audio pass-through for non-destructive monitoring
App price: $2.99.
