To add to what others have said--
The spectrogram image contains amplitude, but not phase information. (There are partial exceptions in special cases involving oversampling.) Conveniently, the human auditory system is primarily sensitive to the same information present in the spectrogram.
- high_byte 6y agoI wonder what phase sensitivity would sound (hear?) like
- JKCalhoun 6y agoI have been told we cannot distinguish phase. I have been told audio -> FFT —> audio (the kind of standard audio compression/decompression algorithms we use) lose that phase information and we can't tell. I have been told the "phase information" is the imaginary part of the complex numbers that are involved in an FFT.
