Importing Audio from a Minidisc Recorder
To import audio into Soundtrack Pro from a minidisc recorder, first turn on your minidisc recorder in playback mode.
Then set the headphones audio level to its maximum (we'll use Soundtrack Pro or the Mac computer to set the audio input levels later).
Plug one end of a 1/8th inch mini-to-mini cable into the audio input jack on the computer. Plug the other end of the cable into the headphone jack of the minidisc player.
On your Mac computer, click on the Apple Menu icon at the very top left, and select System Preferences in the menu.
In the System Preferences menu, click on the Sound Icon:
Click on the Input tab at the top and make sure Line In...Audio Line-in port is chosen.
Below move the Output volume slider all the way to the right (the maximum setting). Make sure the Mute box is not checked.
Now you can use the Input volume slider to adjust the volume level of the audio you want to import from the minidisc player to the computer.
To do this, press play on the mindisc recorder. Then use the Input volume slider to adjust the audio levels, which are displayed on the Input level meter.
Make sure the loudest audio in your recorded audio segment registers no more than three bars in from the far right of the Input level meter. This will avoid distortion of the audio when you import it into your computer.
Once you've adjusted your audio, return to Soundtrack Pro to start the importing process.
