Description
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.
