Audio Analyzer vs P422 Fairuz

The analyzed result of the waveform is rendered at 60FPS.
The following 4 functions can be accessed: Waveform visualizer (oscilloscope) Spectrum analyzer Historical peak Historical FFT Tapping each function enters into full-screen mode and tapping once more exits full-screen mode. Horizontal zoom is only available for the spectrum analyzer.
Magnification gesture (aka pinching) allows for zooming in and out, and frequency offset can be performed by swiping on the screen horizontally. Vertical swiping adjusts input volume.
Coefficients are displayed in the corner.

P422 Fairuz is a four-band op-amp parametric EQ that moves past hardware — the punch and harmonic density of classic op-amp circuits, with capabilities the originals never had. Shape your sound with HIGH, HI-MID, LO-MID and LOW bands, each with three selectable curves (Bell, Contour, Contour X2) and proportional Q: wide stays wide, narrow finds itself. LO and HI shelves with complementary dip behavior, switchable HPF/LPF, and the TREMOR circuit laying a sub-bass foundation below 30 Hz. Character comes from the circuit, not just the curve: OUT drives the op-amp output stage, VOICE adds drive on top of it, and HAMMER adds the output transformer after it, for body, density and saturation — op-amp color available even with the EQ bands off. Blend it all in parallel with the MIX control, no DAW routing needed. FEATURES - Four op-amp EQ bands with Bell / Contour / Contour X2 shapes - Proportional Q — musical at any width - Stepped or continuous frequency modes - LO / HI shelves with complementary dip - TREMOR sub-bass circuit below 30 Hz - Switchable HPF / LPF with position options - Op-amp output stage: OUT drive, VOICE drive and the HAMMER output transformer - MIX parallel blend and Dual Mono L/R behavior - Spectrum visualizer: drag the band dots, tap one for its card; IN/OUT analyzer with freeze, range, resolution, speed and tilt - A/B states and 276 factory presets with notes, tags, search and favorites - Out & Trim linked gain staging - Zero latency, optional oversampling FORMATS - AUv3 plug-in for AUM, Logic Pro, GarageBand, Cubasis and other AUv3 hosts - Standalone app with mic/interface input Bring console-grade op-amp tone to your iPad and iPhone.
