When you select PCM in the Destination area of the Bounce dialog, the following options are available:
File format pop-up menu: Choose the PCM file format (AIFF, Broadcast Wave, or CAF). PCM files can be automatically added to the Project Audio Browser by selecting the Add to Project checkbox.
Resolution pop-up menu: Define the resolution of the bounce file. The options are 16 Bit (for CD delivery), 8 Bit (for multimedia productions,) or 24 Bit (for mastering to DVD).
Sample Rate pop-up menu: Choose the sample rate for your bounce file. Options range from 11,025 to 192,000 Hz, including the three most commonly used sample rates: 44,100 (CD-DA), 48,000 (DAT), and 96,000 (DVD).
File Type pop-up menu: Choose either Split (for use in Pro Tools), or Interleaved (for further use in Logic Pro or with CD writing software).
Note: Choosing Split disables Burn to CD/DVD, if it’s chosen in the Destination area.
Dithering pop-up menu: Dithering is recommended when bouncing 24-bit recordings into 16-bit files. For details on dithering options, see About dithering algorithms.
Surround Bounce checkbox: Available when Additional Surround Options is selected in the Advanced preferences pane. Select this checkbox to bounce all outputs in the project surround format (File > Project Settings > Audio > Surround Format).
All surround outputs are bounced simultaneously, regardless of which output channel’s Bounce button is clicked (or if the Bounce window was opened via File > Bounce). Each surround channel is bounced to a separate file.
The Logic Pro > Preferences > Audio > I/O Assignments pane gives you access to the surround settings.
You set the stereo and surround output formats in the Output pane.
The Bounce Extensions pane displays the extensions that are added to the filenames resulting from a stereo or surround bounce. Select the various fields to edit the extensions.
You set the stereo and surround input formats in the Input pane.
Note: Selecting the Surround Bounce option deselects the MP3, M4A: AAC, and Burn checkboxes in the Destination pane if they’re selected.
Add to Project checkbox: Adds the bounced PCM file to the Project Audio Browser.
