Dear Junfeng, What is termed "in-the-head" localization would be basically any stereo recording played back over headphones. If you try to locate the acoustic sources, they will lie on a line between your ears. An "out-of-the-head" localization, where sound sources are in there more realistic positions, outside your head, requires some sort of binaural encoding, whether through HRTF signal processing or recording on a dummy/real head. To BEST experience this, you can make a recording with some small microphones in your ears. This is well worth doing for any researcher interested in binaural and HRTFs. Some examples of others recording, which I think work well are: The virtual barber shop : http://www.youtube.com/watch?v=IUDTlvagjJA Holophonic ball experiment : http://holophonicballexperiment.com/ You can also do a youtube search for "binaural sound demo" For other examples, and more information, I suggest you contact some of the researchers in Japan who are working a lot on these subjects. I would suggest Dr. Yôiti Suzuki (http://www.ais.riec.tohoku.ac.jp/)and Dr. Makoto Otani (http://www.cs.shinshu-u.ac.jp/~otani/), as I have worked with both of them. There are of course many others in Japan.

As I know, the sound externalization is a big problem for binaural sound reproduction with headphone. While, I have never heard the 'in-the-head' sound and 'out-of-the-head' sound which possibly processed by some signal processing algorithms. Could anyone comment on this issue and provide some sound samples to make me know the impression of in/out-the-head sound samples? Thank you so much in advance.
