Hello again David,
Sorry for bothering you, I have just realised that it's Shift and S for solo
and Shift and U for mute.
My brain is getting old and so much is going on here at the moment, we are
in the process of moving house .
Best Regards, Jim.

Hi Mike,
below are a few more details of the auto duck effect. Note, that you have to
import rather than open files if you want to create tracks out of more than
one file in a project. This is because opening a file creates a new
project, unless the project is a newly created empty project. On the file
menu, open the import sub menu, and choose audio (ctrl+shift+I). So if
you've got two files, you can open or import the first one, but you have to
import the second one.
Auto Duck
The Auto Duck effect reduces (ducks) the volume in the selected audio during
the periods in which the level of another track, known as the control track,
exceeds a certain threshold. The Auto duck effect uses the track which comes
immediately after the last selected track as the control track.
So, for example, if you've got one music track, and one voice track in the
project, and you want to reduce the volume of the music when there's speech
in the voice track:
1.Make sure that the music track is the first track. If it isn't, you can
move a track up or down the track table by opening its menu, and choosing
Move Track Up or Move Track Down respectively.
2.Make sure that the voice track is not selected.
3.Select all the audio in the music track. To do this, first make sure that
the track is selected. Then select a time range that includes all the audio
in the track: press J to move the cursor to the start of the audio in the
selected track, and then press Shift + J to select from the cursor to the
end of the audio in the selected track.
4.On the Effects menu, open the Auto Duck dialog, and if you've happy with
the default settings, then just press Enter to press the default OK button.
Auto Duck settings:
- Duck amount. This is the amount of volume reduction of the selected audio
during the periods when the level in the control tracks exceeds the
threshold. Its given in decibels, and its default value is -12dB.
- Maximum pause. If the time between two periods when the level in the
control track exceeds the threshold is less than the Maximum pause
parameter, then the selected audio continues to be ducked in this time
there isn't a fade up and then a fade down. If for example the control track
contains speech, then if there are pauses less than the maximum pause, then
the selected audio continues to be ducked during this period. The default
value of Maximum pause is 1 second. Note that regardless of this setting the
Maximum pause is always at least the sum of the outer fade lengths, which
are described below.
- Fade lengths. The time over which the volume in the selected audio is
faded down to the reduced volume is made up of two parts. The volume of the
selected audio can start to fade down before the level in the control track
starts exceeding the threshold. This time interval is known as the outer
fade down length, because it occurs outside of the time when the threshold
is exceeded, and its default value is 0.5 seconds. In addition, the volume
can finish fading down after the threshold starts to be exceeded. This
interval is known as the inner fade down length, because it occurs inside
the time when the threshold is exceeded, and its default value is 0 seconds.
In an entirely similar manner, the time over which the volume in the
selected audio is faded back up is also made up of two parts: the inner and
the outer fade up lengths, which have default values of 0 and 0.5 seconds
respectively.
- Threshold. The selected audio is ducked during the periods when the level
in the control track exceeds this threshold. It's given in decibels, and its
default value is -16dB.
David.

Hi Robby,Could you explain how to use the audo duck feature in
step-by-step instructions? I looked at the built-in manual that comes with
Audacity, and like many articles we find online that explain how to do
something, theyre assuming that the user is using a mouse, and Im not
able to use the mouse. Im hoping to create a recording that simulates a
radio broadcast like sound. Whereas, at the beginning, theres
approximately 15 seconds of instrumental music, then at the point where the
narration would begin, the music will fade down but continue to play at a
comfortable level so that it doesnt get in the way of the voice track.
Thus, allowing the listener to hear both the music and voice track. Then,
when the voice track ends, the music will fade back up and play for a few
seconds, then fade out.
Thanks.MikeRochester, NY. USA

You can use the Auto Duck effect to create a voice over. Make sure the
voice track is below the music track and use the track align options to
move the voice track to where you want it to start. Then make sure only the
music track is selected, select the audio by pressing j shift-k and apply
Auto Duck. If you want The music to fade to silence during the voice track
cut it off where you want it to end and perform a fade before applying Auto
Duck. Cheers,

Hello fellow Audacity users,I'm in the process of creating a demo
recording for an online radio station to which I'm thinking about joining
in the near future.I'd like to add music to an already existing audio file
in such a way that I can combined the music and the audio file together.
Thus, when the completed file is played back, in the beginning of the
recording, the music will start to play first, then after so much time, the
music will fade slightly and the audio file containing me speaking will
play, creating a smooth balance between my voice and the music, similar to
what happens when someone is talking live over the radio with background
music playing.
Then, once that recording is done, I can fix it so that the music will
either fade back up, or fade to silence completely, when the speaking
portion of the recording is done. Thus, allowing me to create a somewhat
professional sounding recording. I say somewhat professional, because I
don't have any pro audio equipment or anything fancy like a studio would.
Also, is there a way to get audacity to record in stereo?
Thanks.MikeRochester, NY.
