  • Trivia

    • Goof: Angela claims to have boosted the audio-recording above the Nyquist-frequency. On the one hand this is very unlikely since most digital-cameras use some sort of video and audio-compression, so frequencies a human can not hear would not have been recorded by the camera. On the other hand, the Nyquist-frequency is the resolution-limit of a frequency-based encoding of an audio-sample, which actually says, the sampling-frequency must be at least the double of the maximum frequency to be properly encoded (Shannon-theorem: f_s >= 2 * f_Nyquist). Therefore, even boosting the recording as Angela claims would not reveal any extra audio-information since it would simply not have been recorded.
