A dual-channel FFT analyzer for iPad and Mac.

Transfer function, real-time spectrum, spectrograph and sound level in one instrument. Consistent resolution across the spectrum, automatic delay finding, and a full SPL section, native to iPad and Mac and built for the field.

Transfer function.

Magnitude and coherence across the full band, with consistent resolution from the bottom octaves to the top. Coherence rides the same graph, and a threshold rejects data below the confidence you set.

Magnitude and coherence, consistent resolution
Automatic delay finding, aligned to the reference
Fractional-octave smoothing and a coherence threshold
Target curves exchanged with other industry-standard software

$Transfer function magnitude and coherence above a fractional-octave spectrum$

Spectrum and spectrograph.

Fractional-octave RTA from 1/6 to 1/48 octave, banded and line at once. Alongside it, a spectrum-over-time spectrograph with amplitude mapped to colour, an adjustable dynamic range, and a scroll rate you set to read decay or catch transients.

1/6 to 1/48 octave RTA, banded, line, or both
Fast, medium and slow averaging
Spectrograph, spectrum-over-time, colour-mapped
Dynamic range and scroll rate, adjustable
Selectable palettes

Sound level, not one metric at a time.

LAF, LAS, LAeq, LCS and LCeq on screen together, calibrated to true dB SPL. Add custom meters with their own weighting, time response and Leq integration, and keep the two that matter in the header with traffic-light thresholds.

Five meters at once, plus custom
A / C / Z weighting, Fast, Slow and Leq
Peak and Leq with your own integration window
Traffic-light thresholds on the header readouts

Sound-level meter suite: LAF, LAS, LAeq, LCS, LCeq and custom meters

Sound-level detail with header-readout selection and colour thresholds

One screen. Touch-first.

Two panes or full-screen, any view over any view. The controls for each graph sit where you're looking, and a frequency cursor reads any point. Native on iPad and Mac, not a desktop layout squeezed onto a tablet.

Split or full-screen, any combination
Per-view controls, in place
Frequency cursor on every graph

Any interface, any channel.

Class-compliant USB, multichannel, following the device's sample rate and channel count. Assign measurement and reference from anything it offers, and rescan on the fly when you repatch, without leaving the measurement.

Multichannel USB, 32 channels and beyond
Measurement and reference, any channel
Rescan on the fly, no restart
