iMovie 11 allows you to set the volume for specific portions of the audio track. You can adjust the sections of volume control and set fade in and out times for each section. You can also apply audio effects, filter sound using an equalizer and layer multiple tracks of audio.
Hi this is Gary at MacMost Now.On today’s episode lets look at audio editing in iMovie 11.So iMovie 11 introduces some new audio features.So lets learn how to edit audio in iMovie 11.So here I have a project and I’ve placed the clip in the main project area at the top.I can switch it to a single row view which is kinda like a timeline by clicking here.Then I can turn on the audio wave form viewer by clicking this button in the middle of the screen.Now I can see the audio wave form at the bottom.The first thing that I wanna show you is volume control.So you can grab the line here which gives you the volume for the entire track and drag it up or down and you can see a percentage.
This is nothing new , you could’ve done this in the audio inspector in iMovie 09.What is new is that you can select just the audio area by clicking on it and select a section of it like this and then adjust the volume for only that section and you can see what happens.I lowered it just for that section there and I have small little handles here that can actually drag out the fade in and fade out for that section.I can continue to do that for other sections as well say increasing the volume on this one,say decreasing the volume here and I can also grab the line here selecting the entire movie clip drag it up and down.See it changes the non specialized areas.These stay the same while the overall wiring for the rest of the track will change and I can reselect any one of these sections,change its handles, even change the area of the volume change.
Now,before I could also detach the audio by selecting clip detach audio,I can mute the entire clip and I can remove all the volume adjustments that I made just like that.I can also add audio effects.I can select the track and hit I for the inspector.So you see the inspector is clip,video and audio and you think you could use audio for audio effects but in fact for effects you stay on the clip side and you have the audio effect pop up here and theres many things you can choose.Just some basic stuff,here for some special effects that you can play with.
In addition, you can also go to the audio inspector here and there are many things that you can change.You have the ability now to reduce background noise.So,this is pretty simplified for iMovie so it may not work in all cases but you can check that off and then select a percentage and try different amounts to see if you can educe noise in a particularly noisy audio track.You can also set an equalizer here,you can change it to something default like say music enhance or hum reduction and it will show you what its done here.Or you could adjust yourself and lower or raise different frequencies of the sound and you can simply turn it off like that.
And as before you can also normalize clip volume to bring lower levels of volume up to a level that makes sense for the video.
Now, as before you can add multiple layers of audio.So,for instance I’ve taken this bit of audio thats attached to the video itself I can bring it extra bits here and add them either to the entire project or to just this track and you can see its pasted there below and I can do adjustments there as well and I can continue to place extra pieces of audio like that.You can see it places them on top of each other and I can adjust the volume controls there and in addition to that adjust specific pieces of it here.
So,the ability to add a special effects,filters and also adjust specific sections of the audio is something we dint have before iMovie 09.You had to bring it into a garage band in order to have that level of control.You can still bring it into garage band for even more control but most of the reason for that is now gone that we can actually edit audio pretty well in iMovie 11.
So, I hope you liked this look at editing audio in iMovie 11.Till next time, this is Gary with MacMost Now.
