HOW TO CLEAN NOISY AUDIO RECORDINGS
WITH BLAZE AUDIO'S NOISE REDUCTION EFFECT PLUGIN
Remove hiss, hum,
sounds of wind and rain, audience noise, pops, clicks, crackle, and all
background noise from recorded audio with the Noise Reduction Effect.
The
Noise Reduction Effect is sold as a plug-in to Blaze Audio's RipEditBurn Plus,
RipEditBurn, and Wave Creator.
1. Locate a section in your audio file
which contains just noise (hiss, hum, crackle, audience noise, pops, clicks,
rain, and other sounds that persist during the recording) but does not contain
music or voice: a section which otherwise should have been silent. Noise can
often be isolated at the beginning or end of a file, and in pauses in the sound
during the music. This section can be very short. Selecting the area around a
short silence in the music and enlarging the waveform (View menu->Zoom to
Selection) can make it easier to find areas that only contain noise.
The
Noise Reduction Effect includes 8 preset samples of common audio noise, in case
you cannot find a silent section in your file.
2 Charlotte Olympia Kitty Flats.
Select the Noise Only section in your file by holding down the left mouse button
and dragging the cursor over the area with the noise you want to remove. The
selection can be quite short. The selected area will be highlighted.
3.
From the Effects menu, choose Noise Reduction. The Noise Reduction Effect dialog
box opens post by haiyan701. Save your noise profile for future use by checking
"Save Profile" and entering a name in the window. Click on the Calculate Noise
Profile button. This will build and save a noise identity for the selected
section. The dialog box will close automatically.
Select the section of
audio which needs to be cleaned, or select nothing if the entire file needs to
be cleaned.
Once again, choose Noise Reduction from the Effects menu.
In the dialog box, use the Noise Reduction Level slider to set the level
to 3 Charlotte Olympia Kitty
Flats.
Click on the Remove Noise button. The noise will be
subtracted from the file, using the last calculated noise profile, unless you
select a different noise profile from the drop-down menu. Listen to the
results.
The noise in the file on the left has been removed. There is now
silence before the music starts, as represented by the straight line, and the
noise of the audience has also been removed from the music itself.
If
the audio is distorted, click Edit->Undo, select the section of audio to be
cleaned (or select nothing if the entire file needs to be cleaned), select Noise
Reduction from the Effects menu again, and this time, reduce the Noise Reduction
level one step, and try again.
There's no need to calculate Noise Profile
again for the same file (in fact, if you saved your profile, it will now appear
in the drop-down menu next to Load Noise Profile every time you use the Noise
Reduction Effect).
If not enough noise is removed, undo the operation
and, open the Noise Reduction Effect again, and set the level to a higher
number.
Noise Reduction Level: This controls the intensity with which the
noise components are removed. A high value will remove the noise more
aggressively, but might also affect the original voice or music. A low value
will remove the noise less aggressively, affecting the original voice or music
less, but at the cost of leaving some noise in the signal.
The Noise
Reduction Effect is sold as a plug-in to Blaze Audio's RipEditBurn Plus,
RipEditBurn, and Wave Creator.
