Sonarish

什么是 Sonarish？

Most sound apps are a free dB readout full of ads or a cloud mic that uploads your audio. Sonarish is four acoustic instruments running 100% on-device — the audio pipeline has no internet permission, so it can't upload. Standouts: phone-as-sonar breathing from an inaudible ~19 kHz tone, machine-fault screening (envelope spectrum + spectral kurtosis) normally locked in $2k analyzers, and a calibrated dB(A) meter with timestamped PDF/CSV reports. Hand-written C++ DSP core, native iOS + Android.
