Using Windows Core Audio (WASAPI) loopback capture for audio frequency detection:
- Initialize
IAudioClientwithAUDCLNT_STREAMFLAGS_LOOPBACK. - Ingest 48kHz stereo float PCM audio packets.
- Compute Fast Fourier Transform (FFT) on 512-sample audio buffers.
- When weapon headshot dink or shield break audio frequencies (4.2kHz - 5.1kHz band) spike by >18dB above noise floor, log confirmed hitmark feedback in < 3 milliseconds!
Zero memory interaction with the game process!
