NEW IN 2.0

Waterfall spectrogram — see sound over time, full screen or right under the bars. Find hum, ringing and feedback as it happens.
Built-in signal generator — pink noise free; white noise, sine and log sweep in Pro. Measure while it plays: no second app.
56 color themes, LED-segment bars, color by level or by frequency, and glow.
A redesigned studio look with broadcast-style LED meters.
Try every Pro tool free for an hour by watching one short video — or unlock color themes one at a time.

ACCURACY YOU CAN TRUST

A tone reads its true level under every window (Hann, Hamming, Blackman, Flat-Top, Rectangular)
ISO / ANSI band sets anchored on 1 kHz: 31-band 1/3-octave, up to 127 bands at 1/12-octave
A, C and Z weighting (IEC 61672) — display only, so your measurements are never baked with a curve
Peak meter and IEC Fast / Slow RMS, with clip warning
USB measurement mics detected automatically, with the phone's voice processing switched off
Shows which input is live and warns about dropped audio, so you know when to trust a reading
