Audio Display - Audio Regions Audio waveforms represented in the Graphic Editor window are shown as Audio regions. An audio region is a reference to a parent audio file located on one of your local drives. Regions act as pointers to an audio file allowing a graphical playlist to be created within the Notes display. You can display several different parameters of an audio file in the Graphic Editor window. To display audio parameters: In the Graphic Editor window, display an audio track by clicking the track name in the track titlebar and choosing a track from the popup menu. In the track name titlebar, the type of audio data that the Graphic Editor window currently displays is listed next to the track length field. To display different audio data, click the name of the type of data to open up the display data type popup menu. Choose one of the following options: Audiodisplays the audio waveform Volumedisplays audio volume Pandisplays the pan for this track Tempodisplays current tempo graphically Send Vol:displays the send volume of an auxiliary bus Send Pan: displays the send pan level of an auxiliary bus Selecting Import Audio File from the File menu imports an entire audio file within the first open track and displays it as a single audio region starting at the beginning of the track (1:1:000). Metro calculates an overview for the imported audio region so that it can be graphically edited and manipulated nondestructively (the original audio file will never be altered). For example, Copying a 1 Bar selection of an audio region over and over across a track will not create additional copies of the audio file on your hard drive, Metro instead points back to the original audio file using it as a reference for the playback of the copied regions. Such is the beauty of a random access nonlinear digital audio environment, as found here in Metro. You can also record external audio directly into an Audio track. Selecting the 'R' button in the track's titlebar record-enables the track. The Record Device specified within the Digital Audio dialog (Setup menu) determines your record source. Use the track's Levels display in the Tracks window to view the input levels from your record source. When recording into an analog input, such as the Macintosh sound input, you'll need to adjust the input levels on your mixing board or directly from the record source. Note: Metro also allows recording from a digital input if using an audio card that supports it. Input levels cannot be adjusted within Metro when recording from a digital source. Use an external mixer. See Also: Audio Region Editing Working with Audio Tracks and Audio Regions
