Capturing Data from the Sound Engine

After connecting to a machine, you can begin to profile the audio and motion in your game by capturing data directly from the sound engine. All the information coming from the sound engine is displayed in the Capture Log. An entry is recorded in the Capture Log for the following types of information:

Notifications
Markers
Events
Actions
Properties
States
Switches
SoundBanks
Events Preparation
Errors
Messages
MIDI Events
API Calls
- Events
- RTPCs
- Game
  
  Syncs
- Game Objects
- Listener Spatialization
- Positions
- Auxiliary Bus
- Obstruction/Occlusion
- Motion
- MIDI
- Dynamic Sequence
- Spatial Audio
- Others

You can monitor each of these entries using the Performance Monitor and the Advanced Profiler. These views contain detailed information about memory, voice, and effect usage, as well as on streaming, SoundBanks, plug-ins, and so on. For more information on monitoring performance, refer to Monitoring and Troubleshooting with the Performance Monitor. You can also get Wwise to parse the data captured and provide you with some statistics on certain audio elements in your game or project. For more information on gathering statistics, refer to Gathering Statistical Information from a Capture Session.

Wwise uses the following special indicators and color to help you quickly sort through the many entries that can appear in the Capture Log.

Description

Indicators

Dots

The varying shades of dots, whose colors are set by the theme wherein Classic is turquoise and Dark is orange, indicate which items in the Capture Log were captured within 100 ms of the Performance Monitor time cursor position. The brighter the indicator, the closer the entry is to the time cursor's position. You can force the cursor to the timestamp of a specific log entry by selecting Move Cursor to Timestamp from the shortcut menu (Ctrl+\). Alternatively, just double-click the timestamp.

Connected Dots

The connected dots, whose colors are set by the theme wherein Classic is dark gray and Dark is white, indicate which items in the Capture Log are related to each other. They only appear when you select an entry in the log.

Colors

Selected Entry

The entry that is selected in the Capture Log is highlighted in a contrasting gray tone, which varies according to your selected theme. (The Classic theme uses dark gray highlighting, while the Dark theme uses light gray highlighting.)

	Note
	It's possible to select multiple entries, although some display and shortcut menu options will then not be available. Use standard multi-select options, pressing Shift while selecting a range of entries or pressing Ctrl while selecting multiple individual log entries.

All entries that are related to the selected entry are highlighted in a contrasting tone of gray (lighter or darker than the selected entry), depending on the theme.

Errors

All errors that occur during the capture process display in red.

Messages

All messages display in yellow.

The following illustration shows how the different indicators and colors are used in the Capture Log.

You can also profile some of your ideas or prototypes even before they have been integrated in the game by capturing directly from the Soundcaster in Wwise. For more information on using the Soundcaster, refer to Chapter 32, Creating Simulations.

	Note
	Before profiling your game, you should load all unloaded Work Units back into the project. When Work Units are unloaded, the profiling information may be incomplete and possibly misleading.
