ミカド MI•KA•DO is powered by a 32-bit floating-point audio engine interfacing directly with the WebAudio API. Signal generation occurs at your device's native sample rate (typically 44.1 kHz or 48 kHz).

• Infinite Headroom: The 32-bit float architecture ensures that calculations never clip internally, providing pure signal integrity before reaching the DAC.
• Sample Accuracy: Real-time interpolation guarantees artifact-free transitions and suppresses aliasing during high-frequency generation.

The Master stage controls the absolute output routing and hardware protection.

• Safety Lock: Hard-limited warning triggers at -5dB (56%) to prevent accidental DAC saturation, speaker damage, or hearing fatigue.
• Panning (L/R): Adjusts the stereo image. Use absolute Left or Right to test for channel separation and cross-talk.

Waveforms are defined by their specific harmonic profiles:

• LIN / LOG Scale: Switch the tuning slider between Linear (exact Hz stepping) and Logarithmic (musical octave scaling) response.
• Sine, Square & Saw: Generate pure fundamental tones (Sine) for tuning, or odd/even harmonics (Square/Saw) for testing transient response and clipping limits.

Features 6 distinct noise profiles for advanced acoustic testing:

• White & Pink: Industry standards for electronics calibration and Room EQ (equal energy per octave).
• Red, Blue, Grey & Brown: Specialized mathematical noise slopes for specific frequency band saturation and psychoacoustic testing.

Instantly route signals and test specific frequency bands without altering your main system settings.

• Routing (L/R/All): Isolate specific channels to verify correct RCA wiring, amplifier routing, and speaker placement.
• Band Select: Send predefined frequency bands (High, Mid, Bass, Subsonic) to test crossover points and tweeter/woofer integrity on the fly.

• Acoustic Detection: Emits a test pulse to the left speaker, then an inverted phase pulse to the right. Use this acoustic method to detect "Out of Phase" (reversed +/- wiring) speakers in your cabin without pulling door panels.

• ISO Frequencies: Steps through exact 1/3-octave industry standard points (e.g., 31.5Hz, 1kHz) for manual DSP EQ tuning.
• RTA Analyzer: Uses the microphone to capture raw acoustic data from your environment.

A dedicated Low-Frequency Effects processing unit for the 0Hz - 120Hz band.

• Drive Limiter: Introduces controlled harmonic saturation to identify mechanical limits and make sub-bass audible at lower volumes.

Sweeps map acoustic behavior to identify "nulls" (cancellations) and "peaks" (resonances).

• Concert Pitch: Calibrate the base tuning from A=432Hz up to 450Hz.
• ADSR Envelope: Shape the tone via Attack, Decay, Sustain, and Release sliders. Extending the 'Release' time is an excellent method for estimating cabin Reverb Time (RT60).

Reference signal generator and distortion detector for perfect gain matching.

• Target Voltage: Enter RMS (W) and final impedance (Ω) to calculate your exact AC target voltage for Multimeter tuning.
• Built-in DD-1 Scanner: Your device uses its mic to detect 'clipping' (THD). Play a 40Hz/1kHz tone, press ACTIVATE SCANNER, and turn up your amp gain until the screen flashes YELLOW or RED. Back it down until it reads SIGNAL CLEAN.
• Phase Scope: Real-time oscilloscope visualizing Left (Cyan) and Right (Pink) channels to detect phase misalignment.

Professional Real-Time Decibel monitoring.

• Weighting: Select dB(Z) FLAT for subwoofers, dB(C) for mild roll-off, or dB(A) to simulate human hearing.
• Peak Hold: Captures the absolute highest acoustic pressure reading.

⚠️ PRO HARDWARE ADD-ONS

For precise measurements above 100dB and accurate Sub-Bass frequencies, the internal mobile microphone is NOT sufficient due to built-in hardware limiters. We recommend connecting an external measurement microphone via USB or adapter.

• Recommended Mics: Dayton Audio iMM-6C (USB-C), miniDSP UMIK-1 (USB), AudioControl SA-4140i.
• Calibration: Plug in your external mic, select it from the "MIC SOURCE" dropdown, compare the reading with a reference meter (e.g., Term-LAB), and adjust the "CALIBRATION OFFSET (dB)" until the numbers match perfectly.
