To record: Set the recording device and input source, adjust the input level, then press the red Record button.

1) Set Recording Device either in the Audio I/O tab of Preferences or in Device Toolbar. Audio I/O Preferences lets you choose stereo recording if required.

2) Set input source for that device (for example, microphone or line-in) in the dropdown selector of the Mixer Toolbar, or (on some systems) at Recording Device in the Audio I/O tab of Preferences or in Device Toolbar.

3) Adjust input level using the right-hand slider on the Mixer Toolbar. Correct adjustment of level before recording is essential to avoid noise or distortion.
