Using Windows Core Audio (WASAPI) loopback capture for audio frequency detection:

1. Initialize IAudioClient with AUDCLNT_STREAMFLAGS_LOOPBACK.
2. Ingest 48kHz stereo float PCM audio packets.
3. Compute Fast Fourier Transform (FFT) on 512-sample audio buffers.
4. 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!

WASAPI loopback audio FFT is the ultimate non-invasive hit-confirmation technique. 0 memory reads.

Pure Windows API and math. Extremely creative.
