Changing The Headphone Output into a Mic Input
Some Macbook Pro's have a dual 3.5mm jack port. This allows you to change it from being a headphone output, into a Microphone input.
If you don't have a dual port, you can simply use the line in input without any sound preference configuration.
Here is how you do it:
1. Click the APPLE in the top left hand corner of your desktop.
2. Navigate to SYSTEM PREFERENCES.
3. Open the SOUND preference window.

6. Close the sound preference window.
The Macbook Pro 3.5mm port is now setup as a MIC INPUT, and you are now ready to start using Audacity.
Using Audacity
- (For Macbook Pro headphone / microphone port setup refer to page 3 of this article).
- One mic selects the input source. Select your “Built-In Input / LINE input”
- For the second Mic, click the triangle beside it and select “Start Monitoring”
Audacity will now be looking for an audio input signal. If a signal is present you will see two red lines (left, right) pulse up and down in the metering window. This allows you to monitor how loud your recording is. Note: At this stage you should see no audio signal.
- Play the loudest section of the song, in order to get a good reference for your recording level.
- Beside this monitoring bar you have a MIC input volume fader.
- Adjusting this fader will adjust how loud you record your mix.
- Recording too loud will result in distortion / a bad sounding mix.
- Record for 20 seconds then press STOP.
- Listen back to the recorded audio.
- If its distorted turn down the input gain.
- Repeat this process until you are happy.
- Audacity is now ready to start recording your mix.
- Remember to SAVE your mix once you have finished recording.
