Hi all,

Does anyone know what program I can use to eliminate the "whine" in the video from the z-750? I have read some people say that an audio filter will eliminate it...what audio filter and how exactly do you do it? I downloaded the free trial of ulead studio 9 but couldn't seem to do it with that...I have adobe premier pro but I can't seem to do it with that...any suggestions would be helpful. thanks!

extract the audio first and save as wave file. use any audio editing program to eliminate the whining sound. best filter to use perhaps is a band stop filter. you just have to determine the exact freq of the noise to effectively reduce it by band stop filter

Mine Z750 emits almost exactly 7600 Hz+-10 Hz but level is a -40 db... Heard only with certain soundcards, none when playing from DVD (without audio tampering/filtering). Seems that various Z750-s vary with this issue :-(

Best, JR
