hi this is gary with macmost now on
today's episode let me show you how you
can trim audio using QuickTime Player
so my episode 647 I showed you how you
can use the QuickTime Player in Lion to
edit video well you can also do the same
in audio you can trim audio and I got a
lot of questions from people that want
to know how to trim a little bit of
sound off the beginning or end of some
audio or to break up an audio file into
several parts you can do that in
QuickTime Player let me show you so here
I've got an audio file right here I'm
going to just drag and drop that on to
QuickTime Player and it will open up at
a very simple player interface and I can
play it hello this is a test now to trim
this audio what I would need to do is go
to edit and trim command T is the
shortcut now I can see the waveform in
here it's pretty compressed so I want to
grab the right side and drag it over
here to the right so now I can see it a
little bit better and it's easier for me
to select so trim I basically grab the
left side there go to where I want to
start grab the right side right there
once I got exactly what I want
I click the trim button and now I just
have that one portion of the audio now I
can go to file and export and export out
just that one portion as a new audio
file now say I want to split up an audio
file in several parts well I've just
trimmed down and exported the one part I
can do command Z or edit undo trim and I
get the original back then I can go trim
again and grab the next portion it's a
manual process but it's pretty quick so
you can see here I can actually even use
keyboard shortcuts or everything I'm
just going to hit return and that's the
same thing as accepting the trim I can
do for export shift command S and then
command Z for undo command T for trim
again and I'm back to selecting the
third portion there and return shift
command s export it etc
so you don't have all the fancy options
like being able to export as other file
types you'll be able to adjust the audio
things like that you just have the
basics of being able to trim things NASA
can come in very useful if say you have
some audio that you want to bring in to
another project like say iMovie or using
keynote or even pages so it's really
good for that or anything else then
you'll probably want to go into a more
advanced audio editor like for instance
GarageBand is perfect for that kind of
thing until next time this is gary with
