FreqCheck™

Acoustic metrology is no longer tethered to the rack. FreqCheck replaces cumbersome hardware interfaces, archaic desktop software, and tangled cables with pure edge-computing power. Powered by the patented IND CORE™ engine, FreqCheck delivers the exact 32,768-point FFT mathematical rigor of traditional rack-mounted analyzers directly from the device in your hand.

Observe the video architecture above. The interface remains locked at true zero when idle, demonstrating absolute resistance to spectral leakage or algorithmic artifacting. Upon receiving a certified external frequency, the IND CORE™ engine instantly calculates dynamic FFT bin allocations, locking onto the mechanical displacement with extreme systematic precision.

Traditional analysis requires routing 48.0 kHz data through specialized ADCs into outdated desktop environments, only to export easily manipulated CSV files. FreqCheck eliminates the bottleneck through high-fidelity, post-process acoustic auditing. Import professional uncompressed and lossless audio formats (.wav, .flac, .alac, .aiff, .m4a, and .mp3) directly into the IND CORE™ engine.

• Extreme High-Fidelity Ingestion: The engine effortlessly handles massive audiophile files up to 24-bit / 384 kHz without processor bottlenecking or thermal throttling.
• Automated Standardization: All imported media is dynamically aligned to the 44.1 kHz laboratory standard prior to analysis. This ensures absolute mathematical consistency in FFT bin widths and sub-Hz measurements, completely eliminating the scaling drift commonly found in legacy software.
• Legacy-Grade Metrology: Delivering the exact 32,768-point FFT mathematical rigor of traditional hardware, FreqCheck bypasses easily manipulated raw data outputs. Every live measurement and file import is instantly secured with an ISO 17025-aligned, SHA-256 cryptographically sealed PDF report.

The FreqCheck platform natively interfaces with top-tier industrial instrumentation environments. By bypassing standard mobile audio constraints, the DSP engine accepts calibrated external analog telemetry filtered through precision hardware setups—such as premium external data acquisition (DAQ) modules like professional ROGA DAQ systems via direct DC-coupled line-in inputs, or class-compliant digital USB interfaces that stream pre-converted telemetry directly into the IND CORE™ engine without requiring external mobile interface modules.

To support deployment teams, metrologists, and researchers in the field, FreqCheck features the integrated Nyquist Forum portal. More than just a discussion community, this network serves as an elite collaborative environment where field personnel log verification data, map environmental anomalies, and share cryptographically signed reports. Operating natively within this ecosystem is Nyquist, an integrated automated intelligence assistant designed specifically to guide users through complex signal profiles, analyze FFT bin centers, confirm uncertainty margins, and streamline compliance workflow documentation. It provides real-time oversight to ensure every field execution aligns with the highest international standard of metrological authority.

Every field measurement generated by FreqCheck is mathematically sealed. Real-time capture telemetry is anchored to the exact hardware signature of the deploying iOS device and instantly bound by a SHA-256 cryptographic hash. The resulting PDF documentation creates a legally defensible, tamper-evident audit trail suitable for FCC Part 90 verification, structural compliance reporting, and enterprise liability defense.

FreqCheck does not estimate; it verifies. The underlying DSP architecture is tested and certified against exact, NIST-traceable SI unit benchmarks.

• ISO/IEC 17025:2017 Calibration (Cert #05122C9A 2602) - Independently verified by Florida Standards Laboratory to government metrology benchmarks.
• NIST Traceability - Systematic algorithmic offsets publicly documented and proven.
• Zero-Knowledge Edge Processing - 100% local signal computation ensuring absolute corporate data privacy.
