Spectral FFT Analysis

Rule 0: Inference is not proof. Spectrogram analysis provides circumstantial acoustic evidence, not cryptographic certainty of master provenance.

Estimated Ceiling

FFT High Frequency Cutoff

16 kHz:File declared as high quality or 320 kbps exhibiting a hard cutoff <= 16.5 kHz, characteristic of an upsampled 128 kbps MP3.
18–20 kHz:High-fidelity MP3 320 kbps or AAC with nominal encoder cutoff (18.0 - 20.5 kHz). 100% club sound system compliant.
22+ kHz:Lossless audio with full audible frequency response (>= 19.5 kHz).
