Mixing Multitrack Sessions
To change background mixing settings:
Right-click the Mix Gauge, and choose any of the following:
• Disable Background Mixing.
• Lower Mix Priority When In Other Applications.
• A Mix Ahead setting to determine how far ahead of the current time Adobe Audition
begins mixing. Longer settings allow for faster mix editing, but they might cause drop outs.
• Mix Entire Session to create a new background mix each time you edit a mix.
• A Mix Priority setting to determine the processing priority of background mixing
versus other tasks.
Disabling background mixing can improve performance when you need to extensively
edit a mix.
To manually start background mixing:
Choose Edit > Refresh Now.
To view or hide the Load Meter:
Choose Window > Load Meter.
Using sessions as SMPTE masters or slaves
By using sessions as SMPTE masters or slaves, you can synchronize the transport controls
of Multitrack View with a MIDI sequencing application or an external hardware device,
such as a videotape machine. Before using a session as a master or slave, you must set
general SMPTE options that apply to all multitrack sessions. (See “Setting up for SMPTE
synchronization” on page 40.)
As a SMPTE master, a session generates timecode in the SMPTE time format you select for
the timeline. As a SMPTE slave, a session receives timecode generated elsewhere, reporting
the following synchronization statuses in the left of the status bar:
• Opened MIDI Input Device when waiting for incoming timecode.
• Synchronizing when establishing synchronization. (Adobe Audition requires about 5
seconds of timecode, known as preroll, to establish synchronization.)
• Playback Synchronized when synchronization is established.
