PCM bounce options in Logic Pro for Mac

When you select PCM in the Destination area of the Bounce dialog, the following options are available:

• File Type pop-up menu: Choose the PCM file type (AIFF, WAVE, or CAF). PCM files can be automatically added to the Project Audio Browser by selecting the Add to Project checkbox.

• Bit Depth pop-up menu: Define the bit depth of the bounce file. The options range from 8-bit to 32-bit float.

• Sample Rate pop-up menu: Choose the sample rate for your bounce file. Options range from 11.025 to 192 kHz, including the three most commonly used sample rates: 44.1 (CD-DA), 48 (DAT), and 96 (DVD).

• Format pop-up menu: Choose a format:

  • Split: Create a separate audio file for the left and right channels of a stereo mix or a separate audio file for each channel of a surround mix. Channel indicators are added to the file names. To customize the indicators, see Bounce Extensions settings.

    Note: Choosing Split disables Burn to CD/DVD, if it’s chosen in the Destination area.

  • Interleaved: Create a single audio file, which contains the left and right channel of a stereo mix or all the channels of a surround mix.

• 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 Enable Complete Features is selected in Logic Pro > Settings > Advanced. 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 > Settings > 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.

• Add to Music checkbox: Check this box if you want to add the .m4a file to your Music library.

  Note: If your Mac is running macOS Mojave or earlier, an “Add to iTunes” checkbox replaces the “Add to Music” checkbox.
