Calling for Android testers on a clean-room, terminal-friendly FOSS audio project: FieldVox Lab EVP Recorder, hosted on Codeberg:

[https://codeberg.org/Exalted6165/fieldvox-lab-evp-recorder]

Key architecture highlights:

• Zero network permissions: No telemetry, no ads, no analytics, no Google Play Services dependencies (built and tested for AOSP, GrapheneOS, and LineageOS).

• Native C core: Real-time AAudio engine with lock-free ring buffers and deterministic C17 DSP, paired with an automatic Java AudioRecord fallback.

• Inspectable output: Writes standard canonical WAV files and timestamped, frame-exact JSONL forensic logs - no opaque binary databases or proprietary wrappers.

• Feature set: Flat baseline capture, vintage DR60 ADC emulation, magnetometer EMF tracking, native pitch-preserved time-stretching, and real-time PCM reversal.

A signed APK with SHA-256 checksums and ADB installation instructions is available directly in the repository:

sha256sum -c apk/fieldvox-evp-recorder.apk.sha256

adb install -r apk/fieldvox-evp-recorder.apk

Feedback on native audio behavior, latency, and hardware edge cases is welcome.
