Setting Project Properties

Each project has a set of project properties that include sample rate, overlap mode, selection mode, timecode, file management, and music-related properties. You can change the project properties for a particular project using the multitrack project controls at the top of the project pane or the Project tab.

Figure. Multitrack project controls.

Each project property has a default setting. You can also change the default project properties for new projects in the Project pane of the Preferences window. For information on setting preferences, see Setting Soundtrack Pro Preferences.

Automation Mode

You can automatically record movements you make to faders, sliders, and other onscreen controls using the pointer. You record automation in Soundtrack Pro by selecting either Touch or Latch automation mode in the project controls, then changing volume, pan, and effects settings as the project plays.

To set the automation mode
  • Choose Read, Latch, or Touch from the Automation Mode pop-up menu.

For more information about the automation mode, see Recording Automation Data.

Nudge Amount

The nudge amount determines how far your selection is moved when you use the Nudge command.

To set the nudge amount
  • Choose the nudge amount from the Nudge Amount pop-up menu. The choices are:

    • 1 Second

    • 10 Frames

    • 1 Frame

    • 1/4 Frame

    • 1 Subframe

Sample Rate

The project sample rate determines the number of samples per second Soundtrack Pro uses for audio playback and export. When you add audio files to your project, their sample rate is matched (upsampled or downsampled) on the fly to the project sample rate with no change to their pitch or file duration. The available sample rates are 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. The default is 48 kHz, which is the standard for digital video and DVD projects.

Note: When creating a soundtrack for a video, be sure you save and export your project at the same sample rate the final video project will use.

To set the sample rate
  • Choose the sample rate from the Sample Rate pop-up menu. The choices are:

    • 32.0

    • 44.1

    • 48.0

    • 88.2

    • 96.0

    • 176.4

    • 192.0

      Figure. Sample Rate pop-up menu.

Note: If you open your project on a computer that cannot support the project sample rate, the project is resampled to the nearest rate the hardware supports for playback. When you export your project, it is exported at the project sample rate, regardless of hardware limitations. For more information on hardware sample rates, see Setting Up Your System.

Overlap Mode

The project overlap mode determines what happens when you move an audio clip so that it partially or completely overlaps another clip in the Timeline. There are two overlap modes—crossfade mode and truncate mode.

In crossfade mode, when you drag an audio clip so that it partially overlaps another audio clip in a track in the Timeline, a crossfade is created for the overlapped part of the two audio files. You can adjust the boundaries of the crossfade in the Timeline. In truncate mode, when you drag an audio clip so that it partially overlaps another audio clip in a track in the Timeline, the overlapped part of the clip is truncated.

To set the project overlap mode
  • Click the Crossfade Mode button to set the project to crossfade mode, or click the Truncate Mode button to set the project to truncate mode.

Setting the Envelope Selection Mode

The project selection envelope mode determines whether, when you select or move a clip in the Timeline, the associated envelope points are also selected or moved with the clip. You can set Soundtrack Pro to either the Select Only Clips mode or the Select Envelope Points With Clips mode.

Figure. Select Only Clips button and Select Envelope Points With Clips button.
To select and move clips and envelope points together
  • Click the Select Envelope Points With Clips button at the top of the Timeline.

To select and move clips and envelope points independently of each other
  • Click the Select Only Clips button at the top of the Timeline.

To toggle between envelope selection modes
  • Press Option-E.

For more information about the envelope selection mode, see Selecting and Moving Envelope Points with Clips.

Choosing the Project Time Format

Each multitrack project has a project time format, which can be either Time (seconds)-based or Beats-based. Setting the time format controls the appearance of the Time display, Time ruler, Timeline gridlines, and available Snap To values. For projects set to Time-based format, time is displayed using the Time Ruler units chosen in the View menu. For projects set to Beats-based format, the time is displayed in measures, beats, and beat divisions. The default format is Time-based.

Setting the format to Time-based lets you align clips and other items in the Timeline with specific points in time, for example, specific frames in a video file. Setting the format to Beats-based lets you align items in the Timeline with measures, beats, and other musical units of time, regardless of tempo. You can switch between Time-based and Beats-based formats while working on a project. You can also set individual tracks to use a different time format than the project’s time format. For information on setting a track’s time format, see Changing Track Time Format.

Setting the Project Ruler Units

You can switch the ruler units for a project in the Project tab and define the details for the ruler units in the View menu.

To choose the ruler units for a project
  • In the Project tab, use the Ruler Units pop-up menu to choose either Seconds or Beats.

When you import a video file into a Soundtrack Pro project, the Time display and Time ruler adjust to show the timecode format of the video. The Time display and Time ruler can display time in seconds, frames, drop frames, or non-drop frames. You can choose the format for timecode display, and you can set the video frame rate for projects not containing a video file. You can also set the default frame rate for new projects in the Project Preferences pane.

To specify the details of the units shown in the Time display and Time ruler
  1. Choose View > Time Ruler Units, then choose one of the following time formats from the submenu:

    • HH:MM:SS

    • Seconds

    • Samples (Audio file projects only)

    • Frames

    • Drop frame (timecode)

    • Non-drop frame (timecode)

  2. If your project does not contain video, you can also specify the following settings:

    • Set Video Frame Rate: Choose from the following: 23.98, 24, 25, 29.97, 30, 59.94, 60.
    • Set Starting Timecode: Enter the timecode for the first frame of your project.

Time Ruler Units and Gridlines

The number of gridlines drawn will depend on the dominant ruler type and zoom level. For example, when the dominant ruler is Seconds and the Timeline is zoomed out, gridlines appear only on the hour marks. As you zoom in, gridlines are drawn on the minute mark. Zoom in more, and gridlines are drawn on the second marks, and so on.
