看來是套上HRTF囉～那麼能聽出如喇叭般的音場嗎？

操作挺簡單，用手機拍自己上半身360度影片，丟過去，回一個檔案就搞定。
拿來幹嘛？用耳機也能聽出音場啊～而且是全球面喔～

Virtual Barber Shop Hair Cut假人頭錄音

這個該是用假人頭錄音，因此必須戴耳機聽，效果非常之好！
唯一遺憾是2:53的聲音該在頭頂，我聽來卻不是...

這幾年聽了一大堆所謂3D錄音、音效，不管是雙耳錄音還是DSP套HRTF處理，絕大多數都非常之差...只有這個效果最真實，其他的音像根本還是完全都在腦中，VR這麼搞哪裡reality了？

HRTF -- head-related transfer function

Wikipedia上這麼說 http://en.wikipedia.org/wiki/HRTF

A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space; a pair of HRTFs for two ears can be used to synthesize a binaural sound that seems to come from a particular point in space. It is a transfer function, describing how a sound from a specific point will arrive at the ear (generally at the outer end of the auditory canal).

重點在...

Some consumer home entertainment products designed to reproduce surround sound from stereo (two-speaker) headphones use HRTFs. Some forms of HRTF-processing have also been included in computer software to simulate surround sound playback from loudspeakers.
