Sonic Lab v1.10 is powered by a 32-bit floating-point audio engine. This provides a theoretical dynamic range of over 1,500 dB, ensuring that signal generation is mathematically perfect even at extreme attenuation.

• Anti-Aliasing: Advanced algorithms suppress digital artifacts during high-frequency generation.
• Sample Accuracy: Real-time interpolation at 44.1kHz prevents "zipper noise" when changing parameters.

The Master stage acts as the final safety and routing barrier for the signal chain.

• Safety Lock: The system triggers a warning at -6dB (50%) to prevent DAC saturation and hearing fatigue.
• Panning: Adjusts the stereo image. Use 100% L or R to test for Cross-talk and isolation between channels.
• System Off: Terminates the WebAudio context to simulate a hardware power-down (CRT discharge).

Waveforms are defined by their harmonic content:

• Sine: Pure fundamental tone. Used for detecting physical resonances in structures.
• Square: Odd harmonics only. Excellent for testing the Transient Response of amplifiers.
• Sawtooth: Contains all harmonics. The most aggressive signal for broad-band stress tests.
• Triangle: Ideal for checking the crossover transition between mid-drivers and tweeters.

• White Noise: Equal energy per frequency. Standard for electronic hardware testing.
• Pink Noise: Equal energy per octave. Calibrated to human hearing; industry standard for Room EQ Calibration.
• Red/Brown Noise: Low-frequency heavy. Used to test subwoofer excursion limits.

Sweeps identify "nulls" and "peaks" in room acoustics.

• Linear (LIN): Moves through Hz at a fixed speed. Used for technical component data.
• Logarithmic (LOG): Spends equal time in each musical octave. Preferred method for acoustic room mapping.

This module tests the "musicality" and transient response of the audio chain.

• Concert Pitch: Fully adjustable tuning (432Hz to 450Hz).
• ADSR: Controls the Attack (sharpness) and Release (tail). Use long release to test room Reverb Time (RT60).

RTA (Real-Time Analyzer): A 72-band FFT visualizer monitors energy distribution.

• ISO Frequencies: Pre-set industry points (31.5Hz, 125Hz, 1kHz) used for standardized documentation.

Specialized unit for the 0Hz - 120Hz band (Subwoofer testing).

• Phase Inversion (Ø): Fixes Phase Cancellation. If bass disappears when sub is ON, toggle this.
• 32-bit Drive: Adds controlled harmonic saturation to test woofer physical limits.
• LFE Sweep: Dedicated low-end sweep to find mechanical rattles in cabinets.
