I dont know if this belongs to here but what ever. So I was trying to replace old winning sound with f1 2010 soundtrack. The problem is that I cant use over 5-7sec long sounds. Original WinRace is 13secs so why I cant make 13sec long custom sounds? About ½year ago I could. If I remember right, my horn was 15 seconds.

The limit varies depending on the quality settings of the .wav
I can't help you anymore than that, because I haven't found out what settings yields the longest sound myself.

Sounds like it's based on the filesize to me.

Do you have the correct bitrate?
