 For Digital Audio
Metro handles digital audio recording and playback using Apple’s Sound Manager 3.2 (or higher), or for OS X, CoreAudio. Metro also supports a number of dedicated audio cards including the Korg 1212I/O and Sonorus StudI/O. Please refer to the user manual of these particular hardware cards for instructions on proper installation and configurations. When properly configured, Metro utilizes multichannel I/O capabilities as well as the higher quality A/D and D/A converters found on those cards. Use the Digital Audio dialog for configuration of Metro’s built-in audio or to address dedicated digital audio PCI cards.
