It’s deeply troubling that emerging technology can be used to extract CVR audio from visualized data we share to help the public understand the circumstances of an accident.
Laws against releasing CVR audio exist to protect privacy, preserve the integrity of NTSB investigations, and out of respect for accident victims and their families during a time of tremendous loss.

Reconstructing audio from spectrogram images uses established signal processing techniques like the 1984 Griffin-Lim algorithm for phase recovery via iterative inverse STFT, not emerging technology or manipulation. en.wikipedia.org/wiki/Phase_voc… equivariant.org/audio-from-spe…
