Configuring Your Audio
Metro supports digital audio on all of the current Macintosh machines. For the purposes of this tutorial, connect your Macintosh audio output to an input of your mixing board or some other source set up for monitoring the output signal.
To configure your audio setup:
- Choose Digital Audio from the Setup menu.
The Digital Audio Setup dialog box appears.
- Under For Metro Digital Audio, do one of the following:
- Click Direct Support and choose Built-in from the Direct Support popup menu. This configures Metro to use the Macintosh's built-in audio capabilities. Under OS 9, Metro requires Sound Manager 3.2 or higher.
- Click Direct Support and choose your external soundcard from the popup menu.
- OS 9 users, click ASIO and choose your external soundcard from the popup list of ASIO devices, if you have downloaded and installed your soundcard’s ASIO driver. We recommend ASIO as a first choice.
- Set the Sample Rate to 44100 and the Bits to 16 (see your soundcard’s documentation for more options for sample rates and bits).
- Click Device Options to open either your soundcard’s control console (if any) or the Sound Manager Parameters dialog box.
- OS 9 users, in the Sound Manager Parameters dialog box, you can set Playthrough, set Input Gain, or click the More button to set Sound Input options (the
Sound Input dialog box looks different for each soundcard you select in the
Digital Audio Setup dialog box).
- Click OK enough times to get back to the Digital Audio Setup dialog box.
- Click OK to close the Digital Audio Setup dialog box.
You have set Metro to work with either your Mac’s internal soundcard, an external soundcard, or an external soundcard with an
ASIO driver.
Now that your audio is configured, proceed on to Plugging In and Testing a Microphone.
Note: older versions of Metro has a Stereo checkbox in the digital audio dialog to record stereo interleaved AIFF audio files. This function is now specified in the tracks window by configuring input select.
