[JohnVo]

hi

i'm looling for a deep tutorial about noise redution , precisely the blue line of frequency

i would love to watch a video

i have searched around youtube i found this tutorial

but there is nothing about how use the blue line and point , sorry but i don't know in english the name of the blue line

i know it let me adjust the noise reduction for specific frequency , in the video linked above the author talks about it's like a keyframe and he's confusing

would appreciate a video about use it

thanks

The blue line is called the Control Curve and keyframes can be added to it to vary the amount of Noise Reduction applied against Frequency. So if you need less NR at high frequencies you could add a keyframe at 1k by clicking on the line and pulling down the keyframe at the end to reduce the NR at HF for instance. The is more about it in the Help file Applying noise reduction techniques and restoration effects . However there is not much info in tutorials because it is only really used for fine tuning critical noise reduction along with other techniques. Just have a play with it to see what it does the next time you use the NR effect in Audition.
