Araya hemen not d\u00fc\u015feyim: Burada verilen threshold ve ratio de\u011ferleri ile elde edilen gain reduction miktar\u0131 sadece bir \u00f6rnek. Farkl\u0131 sinyal i\u00e7erikleri farkl\u0131 sonu\u00e7lar verecektir.<\/p>\n\n\n\n
Peki, madem ayn\u0131 miktarda azaltma (gain reduction) elde ediyoruz, threshold ve ratio de\u011ferleri \u00f6nemli mi?<\/p>\n\n\n\n
Evet, \u00f6nemli.<\/p>\n\n\n\n
