Why is processing only happening for part of my clips?

Report · Jan 05, 2017

So I've got a Premier Pro CC project where I have then launched the audio from PP in Audition CC.

I have about 20 audio clips to work with of the audio from a camera using a Rode mic.

In Audition under Essential Sound
I click Reduce Noise and great it fixes my problem...

...however at the start of EVERY clip it is not fixed, but for the rest of the clip it does.

Why on earth is this happening and how can I fix it?

Note - I did mix down the clips to one track, opened that in Audition however the Essential Sound menu told me "no clips selected" (even though I had the entire waveform selected - isn't that a clip? I tried going via the Effects menu to reduce the hiss/ noise and the presets did not seem to work as well as the repaired part of the Essential Sound menu option for the 20 separate clips.

PLEASE HELP - thanks in advance.

This may be because Essential Sound uses the Adaptive Noise Reduction effect which needs a bit of preview audio to calculate what noise reduction it needs to do. You may be able to get round the problem by leaving a longer handle at the start of the audio clip and editing it off after processing.

In this case it would be better to use the normal Noise Reduction effect where you can preset the settings for the noise reduction. Alternatively apply the Adaptive Noise Reduction to the whole of the recorded audio file before splitting it up into clips in PP. If you save a copy of the file before working on it you will then be able to use the original file name for the processed audio and PP shouldn't know the difference and should keep the clips as edited but use the noise reduced version instead.
