Wwise Help

To create multiple complete SoundBanks in Wwise:

1. Create the SoundBanks you will need for the game and then name them appropriately, for example, “CommonEvents”, “Level_1”, “Level_2”, and “Level_3”.

2. Group your Events into Virtual Folders in Wwise. Create one Virtual Folder per SoundBank and then drag each Virtual Folder into its corresponding SoundBank. By adding Virtual Folders to your SoundBanks, you can avoid having to edit the contents of your SoundBanks every time a new Event is added to your project. When the contents of your Virtual Folder change, the SoundBank automatically gets updated.

3. Add all Events to their respective SoundBanks. This step is only required to add Events that fall outside the original folders, if any. If an Event needs to be in multiple SoundBanks, then simply add it to the required SoundBanks.

4. Generate the SoundBanks and copy the generated SoundBank folder to the game application.

To integrate the multiple complete SoundBanks in game:

1. In the game, simply load the right SoundBank at the right time. For example, the game could load the general SoundBank at the beginning and then load the other SoundBanks based on the player's actual location in the game. Note that some games will need to have enough memory to load more than one “level” at a time, to allow for transitions between levels.

   The following sample of code gives you an idea how these SoundBanks can be loaded in game.

               
               // Initialize the sound engine here. 
               ...
   
               // Load the Init bank and the Common SoundBank. 
               AkBankID  bankID; // Not used in this sample. 
               AKRESULT eResult = AK::SoundEngine::LoadBank( L"Init.bnk", AK_DEFAULT_POOL_ID, bankID );
               if ( eResult == AK_Success )
               {
                 eResult = AK::SoundEngine::LoadBank( L"MyAllInONeBank.bnk", AK_DEFAULT_POOL_ID, bankID );
               }
   
               ...
               // And at various places in the code, based on the actual needs:
               eResult = AK::SoundEngine::LoadBank( L"Level_1.bnk", AK_DEFAULT_POOL_ID, bankID );
               ...
               eResult = AK::SoundEngine::LoadBank( L"Level_2.bnk", AK_DEFAULT_POOL_ID, bankID );
               ...
               eResult = AK::SoundEngine::LoadBank( L"Level_3.bnk", AK_DEFAULT_POOL_ID, bankID );
               ...
               eResult = AK::SoundEngine::LoadBank( L"Level_1.bnk" );
               ...
               eResult = AK::SoundEngine::LoadBank( L"Level_2.bnk" );
               ...
               eResult = AK::SoundEngine::LoadBank( L"Level_3.bnk" );
             

   	Note
   	As an alternative to the LoadBank() command, you could prepare your SoundBanks using the AkBankContent_All command. The advantage of preparing your SoundBanks is that you avoid the possibility of duplicating media in memory. Refer to the section “Preparing Banks” in the Wwise SDK documentation.
