Re: 192kHz Samples -- But Not Really? Reply #25 – 2017-06-23 20:13:48 Here is a way to simulate having ultrasonic hearing with extreme sample rate tracks: (I just downloaded "Vision of Her" in 24/88 FLAC from https://www.oppodigital.com/hra/dsd-by-davidelias.aspx )sox original.wav shifted.wav pitch -2400 sinc 5kThis pitch-shifts down by 2 octaves (2400 cents), then applies a highpass filter at 5kHz. So, the 20-40kHz range is shifted down one octave to 10-20kHz, then another octave to 5-10kHz. The highpass filter at 5kHz then cuts off everything that was below 20kHz in the original recording.More fun (?) than staring at Spek spectrograms and wondering what the ultrasonics might sound like if you could hear them.
