Re: Gaussian vs uniform noise audibility



Eckard Blumschein writes:
Of course, complex representation of a signal requires magnitude as
well
as phase. (Magnitude is always positive while there are positive and
negative amplitudes.) This should once again persuade anybody that the
inner ear does not perform a complex Fourier transform.
Malcolm Slaney's review of Pattern Playback techniques:

was an eye-opener for me -- relatively simple techniques let you invert
magnitude-only, nonlinearly-processed representations back into
faithful (if not bit-accurate) audio.
