Custom Control App vs Spektral Mobile

The Custom Control app provides customized control interfaces for compatible Allen & Heath installed audio systems. The level of control offered, app layout and graphics can be varied for different user types and devices, providing each user with an interface that is optimized for their role. The user interface is designed via a Custom Control editor for Windows and Mac OS – this is typically undertaken by a systems integrator. Access to all levels, mutes, sends, preset recalls, source selection and metering is provided, and tabs can be configured for access to multiple control pages or zones. Once complete, the configuration is uploaded to an Allen & Heath dLive MixRack, ready for deployment. Any device running the Custom Control app can log into the system with a given user name, at which point the correct user interface is downloaded and displayed. This allows for both kiosk applications and bring-your-own-device use, since the configuration is deployed on demand. Features: - Multiple user interfaces (per user, per device type) - Custom graphics and background - BYOD friendly - Optional password protection Allen & Heath is a leading creator of audio mixing systems for live sound and fixed installation. www.allen-heath.com/installation

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.
