If you have a microphone attached to your computer, you can add audio recordings to your entries.
If you own a newer laptop you already have a microphone. Other Macs may also have built-in microphones.
To find out if you have a mic, open your System Preferences and
choose Sound then Input.
Launch the Audio Recorder by choosing Record Audio from the Insert Audio/Video item in the Edit menu. At launch the Title, Artist, and iTunes Album are automatically set. Press the red circle to begin recording. Press the same button to stop recording.
As soon as you finish recording the audio center switches into preview mode so you can listen to the material you've just recorded. If you're pleased with the record press the now active Insert button to add it to the foremost entry.
Tip: hold down the alt/option key when launching the audio window to keep the recorder visible no matter what application you are using.
