The Toolkit

Sound Check's RTA
  • Feedback mode flags the frequency that's ringing, so you know exactly where to cut.
  • 1/1, 1/3, 1/6 or 1/12 octave. A, C or Z weighting.
  • Peak and Max hold, with a cursor that reads any band.

RTA

Sound Check's FFT
  • Store a reference trace, then see exactly what changed — before and after an EQ move, or one mic position against another.
  • Up to 32k points when you need the fine detail.
  • The strongest tones labelled, harmonics marked from the cursor.

FFT

Sound Check's SPL Meter
  • Set your threshold right on the gauge. Go over it and the meter pulses red.
  • A, C or Z weighting. Slow, Fast or Impulse.
  • MAX, AVG and LCpeak, plus the last 30 seconds to scrub back through.

SPL Meter

Sound Check's Spectrogram
  • Low end you can actually read: mains hum at 50 Hz, a room mode at 63 Hz, as two separate lines.
  • Opens on the last two minutes, so you see what just happened.
  • Jump to the loudest moment in view, then step through the next peaks.

Spectrogram

Sound Check's Signal Generator
  • Keeps running while you switch tools. Play pink noise and watch it on the RTA.
  • Sine, square, pink, white, sweep and polarity pulse.
  • Levels in dBFS. Left, right or both.

Signal Generator

Sound Check's calculators
  • See comb filtering happen. Drag the distance between two arrivals and watch the nulls move.
  • Eight calculators, from delay times to amp headroom.
  • Distance, milliseconds and samples as one value.

Calculators

Show Mode

Sound Check's Show Mode after a two-hour show: the level across the whole night, its markers, the LAeq and LCeq lines against the limit, and the show's figures along the bottom
