When you talk into the microphone, you should see the meters in the middle of the panel move-soft sounds are green and near the bottom of the meter, loud sounds are red or yellow and near the top. Otherwise you can use the default or 44100. Sample rate: click the radio button next to 22050. Source: Click the Radio Button next to the appropriate source. Set the recording conditions in the panel like Figure 1. From the New menu, select Record Mono sound.Ĥ. When you have finished this, close System Preferences.ģ. Ideally, you want the recording level to peak about 3/4 of the way across the meter and you can adjust the Gain slider so as to achieve this. You should try to put your mouth about 5-10 inches from the microphone. When you do so, the level meter below should start to show activity when you speak into the microphone. Click on the sound source you will be using.
