<\/p>\nYak\u0131n zamana kadar dijital ortamda sinyal ile ilgili konu\u015furken ‘peak’ dedi\u011fimiz zaman asl\u0131nda ‘sample peak’ten bahsediyorduk. Son y\u0131llarda, \u00f6zellikle EBU taraf\u0131ndan radyo ve televizyon yay\u0131nlar\u0131n\u0131n ses seviyeleri ile ilgili olarak yap\u0131lan d\u00fczenlemelerden sonra, ‘sample peak’ ile birlikte bir de ‘true peak’ terimi g\u00fcnl\u00fck kullan\u0131m\u0131m\u0131za girdi. Her ikisi de ‘peak’ ancak asl\u0131nda birbirlerinden farkl\u0131lar.<\/p>\n
Sample peak, analog sinyalden \u00f6rneklenerek dijital ortama aktar\u0131lm\u0131\u015f sinyalin genli\u011finin (amplitude) en \u00fcst noktas\u0131d\u0131r. Di\u011fer bir deyi\u015fle, sample peak, dijital sinyaldeki \u00f6rneklerin (sample’lar\u0131n) ula\u015ft\u0131\u011f\u0131 en \u00fcst seviyedir. Dijital ortamda sinyal y\u00fcksekli\u011fi i\u00e7in dBFS kullan\u0131l\u0131r. 0 dB, dBFS skalas\u0131ndaki en \u00fcst noktad\u0131r.<\/p>\n
Buradan yola \u00e7\u0131kt\u0131\u011f\u0131m\u0131zda sinyal y\u00fcksekli\u011fi 0 dBFS’i ge\u00e7medi\u011fi zaman sorun olmamas\u0131 gerekiyor. Buna dayanarak y\u0131llardan beri hemen hemen t\u00fcm master ses dosyalar\u0131, biraz da hata i\u00e7in marj b\u0131rakmak ad\u0131na, hep maksimum -0.2 dBFS veya -0.3 dBFS seviyesinde tutuldu.<\/p>\n
Asl\u0131nda durum tam \u00f6yle de\u011fil… \u0130\u015fin farkl\u0131 bir y\u00f6n\u00fc daha var…<\/p>\n
\u015eimdi bir de true peak’e bakal\u0131m… Yukar\u0131da da belirtti\u011fim gibi, sample peak y\u00f6ntemi ile \u00f6l\u00e7\u00fcm yaparken sinyaldeki sample’lar\u0131n y\u00fcksekli\u011fini \u00f6l\u00e7m\u00fc\u015f oluyoruz. Di\u011fer yandan, dijital sinyal hoparl\u00f6rlere g\u00f6nderilmek \u00fczere dijital\/analog \u00e7evrim yap\u0131l\u0131rken a\u015fa\u011f\u0131daki g\u00f6rselde g\u00f6rebilece\u011finiz gibi sinyal seviyesi \u00f6rnekler (sample’lar) aras\u0131nda \u00f6rneklerin seviyesinden daha y\u00fcksek olabiliyor.<\/p>\n
<\/p>\n
\u0130ki \u00f6rnek aras\u0131nda seviyesi \u00f6rneklerin kendisinden daha y\u00fcksek olan noktalara “inter-sample peak” ad\u0131 veriliyor ve bunlar true (ger\u00e7ek) peak olarak nitelendiriliyor.<\/p>\n
Bir\u00e7ok durumda true peak, sample peak de\u011ferine g\u00f6re daha y\u00fcksek oluyor. True peak ile sample peak aras\u0131nda fark \u00e7ok k\u00fc\u00e7\u00fckse hoparl\u00f6rden \u00e7\u0131kan sinyalde bozulma olup olmad\u0131\u011f\u0131 duyulmayabiliyor. Di\u011fer yandan fark b\u00fcy\u00fckse, kulakla duyulabilecek bozulmalar ortaya \u00e7\u0131kabiliyor. Sinyali duymak i\u00e7in mutlaka dijital\/analog \u00e7evrim yap\u0131p hoparl\u00f6re g\u00f6ndermek zorunda oldu\u011fumuzu g\u00f6z \u00f6n\u00fcne ald\u0131\u011f\u0131m\u0131zda, true peak \u00f6l\u00e7\u00fcm metodunun \u00f6nemi ortaya \u00e7\u0131k\u0131yor.<\/p>\n
DAW’lar\u0131n \u00e7o\u011funda \u00f6rneklerin peak noktalar\u0131n\u0131 g\u00f6steren Sample Peak Program Meter (SPPM) bulunuyor. Inter-sample peak noktalar\u0131n\u0131 \u00f6l\u00e7mek i\u00e7in ITU-R BS.1770 ve EBU R128 gibi standartlarla uyumlu plug-in’ler kullanmak gerekiyor.<\/p>\n
