Re: Pitting localisation cues against hamonicity

Title: Re: Pitting localisation cues against hamonicity

In S McAdams’ 1984 PhD Thesis (“Spectral fusion, spectral parsing, and the formation of auditory images”, Stanford University) he reports an experiment at IRCAM in which they spatially separated the odd and even harmonics of a synthesised oboe.  Apparently the listeners heard a single image fused at an intermediate position (but only when the FM was identical).

Subject: Pitting localisation cues against hamonicity

Hello everyone!

My name is Gordon McDonagh and I am trying to find out if anyone has
conducted any research into pitting localisation cues against harmonicity.
 Below is a brief outline of my project, if anyone can suggest any past
research that may help me, I would be most grateful.

Thank you in advance for any help,

Regards, Gordon

Currently I am experimenting with additive synthesis and surround sound.
I am separating sounds into their component parts ie sine waves and
spreading the component sines around a 3D field.  The harmonicity effect
will join the sines together so the subject will hear the original
waveform but localisation cues will try and work out where each single
sound is coming from.

I wish to see which comes out on top (harmonicity vs localisation) and use
the information to develop a synthesis method for surround sound useage.

I am interested in surround sound techniques, additive synthesis,
localisation with multiple sources, Harmonicity and Psychoaccoustics with
paricular reference to Auditory Scene Analysis and Spectral Fusion.
