Surround sound, example DOULBY and 3D surround soud dba? so basicaly prang nsa loob klang ng sinehan, kpg nano2od ka ng cine ung sound sa loob gnun ang surround sound, specialy sa MOA cinemax.
There are lots of things to consired to make surround sound like speaker position, amplifier, surround sound decoder, preamplifier, mixer and lot more. maka2gawa ka ng surroud using 5.1 speaker pwd nrin 4.1 dba mrong REAR, FRONT, CENTER at SUB yan mga yan.just put the speaker in their specific position then ok na mron kanang surround sound.
But the real surround sound system is d nman gmagamit ng mraming speaker, only left and right ang gamit nila.
When i study at the university (course: Sound Engineering) gmawa kmi ng surround sound using only 2 bass left and right, 2 mid left and right also and 2 tweeter left and right also. so basicaly dpat ang mid mo is ngccross sla so that u can creat suround sound.
When i said ngccross ang mid ung sound ng left prang nri2nig din dun sa right speaker pro d gnun klakas at vice versa.
