Here are bits 17-24 (only) from each sample of the above file, moved to bits 2-9 so you can hear them.

Warning: quite loud! (Far louder than the original file).
Warning: DC offset (bit 1 not used, hence all values are positive).

Attached File  13._.Chorus.For.unto.us.a.child.is.born.1min21sec_1min45sec_proc.flac ( 4.52MB ) Number of downloads: 169


EDIT: generated in MATLAB using manual bit shifting. DSP or assembler would have been far more efficient, but I believe the MATLAB result is correct.

Don't want to be harsh but what purpose of such extraction? Point me if I am wrong but separated less significant bits (17-24) don't mimic the original signal and contain pure quantization differences/errors (noise).

P.S. I don't know if it's placebo but I hear some background intelligible sounds
