Even if you dont have a professional recording studio, you can use the speech enhancement and noise reduction features included with GarageBand to make sure your voice is clear and compelling. You can even give your voice a big radio sound using the built-in audio effects. Its like having your own radio engineer.
It all starts with a clear original recording. Make some test recordings before you start rolling to ensure you get the perfect sound.
Ducking automatically lowers the volumes of tracks that you decide are the backing tracks. To turn on ducking, choose Control > Ducking. Ducking control arrows appear in each tracks header. Click the arrow pointing up to make a track a lead track, and click the arrow pointing down to make a track a backing track. To change the amount of ducking for a track, choose Track > Show Track Info, and then click the Details triangle. Drag the Ducking Amount slider to adjust the amount of ducking.
You can record audio from an iChat audio or video conference in GarageBand. GarageBand records the audio of each participant in a separate Real Instrument track. Open iChat and GarageBand and make sure all participants have joined the conference. Click the Record button. A message appears to ask you if you want to record the iChat conference, and reminds you to get permission to record from the other participants. Click OK. When youre finished, click the Record button again to stop recording. You must have Mac OS X v10.4.4 installed to record audio iChats.
The Speech Enhancer settings included with GarageBand offer a variety of ways to reduce noise and optimize the sound of your microphone. If you dont want to use the speech enhancer settings included with GarageBand, you can customize speech enhancer even more. Select the track youre recording to and then click the Info button. Click the Details triangle and then click Edit button (the pencil icon) next to the speech enhancer thats selected for that track.
In addition to making test recordings of yourself before you get rolling, make sure the person you're interviewing is sitting at a comfortable distance from microphone that produces a consistent level. When you're satisfied with the settings for their track, make sure the track is record enabled.
