Virtual Audio Speakers System

   How many lives does Czar Putin demand?
   Putin's tyranny and expansionism must be stopped.
   He cannot justify aggression and crimes against human life forever.

 

  Using headphones or earphones, you feel the sound comes from just close to your ears or from the center of the head. It's quite different from the sound in the audio room with speakers or the real concert hall.
 WVS is a WebApp converts your favorite music to spacial 3D sound by HRTF(head-related transfer function).
HRTF can locate sounds in three dimensions in direction abobe and below, front and rear, left and right,
but not so effective for recognizing the distance of the frontal sound source. Why?

  A sound wave from your front position will directry reach to your ears rather than through your brain, so the time and level difference between both ear (ITD,ILD) and reflection from the wall will be more significant. WVS includes these effects, and also it works efficiently for the sound files mixed of separately recorded tracks in the studio ( Multi-Track Recording ).

 Supported audio codec is FLAC, WAV, MP3, OGG, and requires a PC/Mobile Phones,Tablet supported WebAudio.
 Use sliders to move speakers.  ( x  : distance between the speakers  y/z: height / depth of the speakers. )
