Avid Media Composer Adjusting Audio Levels


Using the Audio Mixer tool is one method of
mixing audio within Avid Media Composer. Let me play through this sequence. “We had a call from fire rescue, that were
three men being extricated from a manhole and unconscious, and not breathing” “Not sure of the cause right away, came to
find out they said it was possibly methane. Inside they were doing work, and I believe
it was a sewer hole. “From the time the run came in, until we got
the victims out was approximately 32 minutes. That’s an excellent time and it just shows
how good of a specialized rescue team we’ve got and how good of a fire department that
we have.” Okay, so the volume level of the music is
too high, and the ambient sound from the rescued workers is too loud. This can be fixed by using the Audio Mixer
tool. If the audio mixer tool isn’t showing, you
can also bring it forward by navigating to the tools menu. The Audio mixer will give you level adjustment
sliders based on the placement of the position indicator within the timeline window. Therefore, since the position indicator is
over these four segments you will have access to four volume sliders. The music segments are on tracks 3 and 4,
which means I should move these volume sliders together. To do this, click on this group icon for each
track you would like to link. So now, I’ll adjust the level of the music
down a bit. You will see a black level indicator within
each clip segment, indicating an audio level adjustment from its original level. It’s important to note that audio level adjustments
are always applied to the entire clip segment. Now, if you do not see a black line after
making an adjustment, make sure you have the clip gain option turned on from the fast menu
that I covered in the previous lesson. Okay, notice the position indicator is parked
over the segment of the second victim being pulled from the sewer. So this means I can also lower its audio level. As you can see, the clip segment is on track
2, which means I’ll move over to the track 2 slider in the audio mixer tool. You can also use the numbered keypad on the
keyboard to type a value, and the volume slider will automatically move to that value as you
type it. You can paste the audio level adjustment from
a single clip segment to other clip segments by marking in and out points in the timeline. Then click on the fast menu at the top of
the audio mixer tool. Choose Set Level on Track in-out. Any clips that are within the marked area
will now match the level of the clip you are parked over. If you need paste an audio level for an entire
track, make sure the timeline window is active, and clear any in and out points by pressing
the G key. Then go back to the audio mixer fast menu,
and notice the menu has changed. This time choose set level on track global. Now, it’s also possible to have audio levels
increase or decrease over time. To do this, you will need to break your clip
segments into pieces. Turn on the sequence tracks for the clip segments
you are working with. Then place the position indicator at the point
where you would like to break the clip segment. Then press the add-edit button. This will break your clip segment in half. Then move the position indicator forward a
bit, and press the add edit button again. Now you should have three pieces of the segment. Park over the segment that you would like
to adjust, and increase the level for that segment within the audio mixer tool. Now, there is going to be a volume jump between
segments. You can soften the transition between volume
adjustments by adding an audio dissolve between the segments. An easy way to do this is mark in and out
points around the areas that you want to cross fade. Then press the quick transition button. Type in a duration of the audio dissolve,
and check the ‘apply to all transitions option.’ Then press the add button. Okay, let’s back up and play to listen to
the audio adjustments. “We had a call from fire rescue, that were
three men being extricated from a manhole and unconscious, and not breathing” “Not sure of the cause right away, came to
find out they said it was possibly methane. Inside they were doing work, and I believe
it was a sewer hole. “From the time the run came in, until we got
the victims out was approximately 32 minutes. That’s an excellent time and it just shows
how good of a specialized rescue team we’ve got and how good of a fire department that
we have.” You should now have a good grasp of using
the audio mixer tool. And don’t forget, GeniusDV also offers classroom
