Spektral Mobile vs AU EngineCore

Spektral is a professional real-time audio analyser for sound engineers. Ring out a PA, find the frequency that is howling, and keep an eye on the level in the room, all from your iPhone or iPad. THREE VIEWS, ONE WORKFLOW • RTA: live spectrum on a logarithmic frequency scale, 20Hz to 20kHz • Spectrograph: scrolling time-frequency heatmap, where feedback shows as a persistent bright horizontal line • SPL meter: A, C or Z weighted, Fast, Slow or Impulse, with the room's history behind it RING-OUT Spektral listens for a frequency that is building rather than one that is merely loud, so a bass note or a mains hum cannot set it off. When it finds one it names the frequency, gives you the musical note, and suggests the notch: centre frequency, Q and cut. Confirmed rings stay in a list as you work through them. LEVEL AND LEQ • Leq over 1 minute, 15 minutes, 30 minutes, 1 hour and 8 hours, all running at once • Three hours of level history on one graph, with min, max and average • Limit Guard: set a limit and a window, and Spektral forecasts how long you have before you reach it • Calibrate against an acoustic calibrator when you need accurate absolute levels PRECISION • 4096-point FFT • Parabolic interpolation for sub-bin cursor and peak accuracy • Peak hold with smooth decay • Smoothing from 1/24 octave through to 1/1 • Frame averaging up to infinite • Musical note display on peaks and cursor TOOLS • Identify: labels the strongest peaks automatically, or just the single worst one • Snapshot compare: freeze a trace and A/B against it • Pink noise generator for reference output TOUCH-OPTIMISED • Horizontal pinch zooms the frequency axis, vertical pinch zooms the dB range • Drag to pan when zoomed, tap to place the cursor • Double-tap to reset all zoom and pan DESIGNED FOR THE STAGE • Full-screen dark interface for low-light environments • Works in portrait and landscape • Uses the built-in microphone or any connected audio interface REMOTE MONITORING (optional in-app purchase) Send this device's SPL readings to Spektral on your Mac over iCloud, so one engineer can watch several positions at once. No subscriptions. No account required. The analyser runs entirely offline.

AU EngineCore app effectively transforms any compatible multi-channel audio interface into a fully configurable digital mixer for live performance. Unlike traditional digital mixers, AU EngineCore offers a software-defined mixing environment, giving users complete control over routing, processing, and signal flow without hardware limitations. A key advantage is the ability to use studio-grade AUv3 plugins directly in live scenarios, enabling advanced processing and creative flexibility that typically requires dedicated studio setups. Built for precision, speed, reliability and real-time performance, AU EngineCore delivers ultra-low latency audio processing, flexible routing, and a clean, distraction-free interface. Key Features • Ultra-low latency audio engine for real-time performance • Advanced multi-bus routing with flexible signal flow • AU plugin support (inserts on channels, buses, and master) • Designed to work seamlessly with most multi-input audio interfaces • Stable performance even in complex live setups • Clean, classic interface optimized for fast operation • Real-time processing with no interruptions or audio artifacts in Live Mode • Multi-channel input and output support • Built for musicians, performers, and sound engineers Built for Live AU EngineCore is engineered to handle demanding live scenarios where stability and speed matter most. Every part of the engine is optimized to ensure smooth operation, even under heavy load. Flexible Audio Setup Connect your audio interface and build your mix the way you want: Route signals across multiple buses Insert AU effects anywhere in the chain Customize your workflow to meet your specific needs. Precision Without Distraction The interface is designed to stay out of your way, so you can focus on what matters: your sound. #nobodysbanda
