Looking at tempo map in general:
Since the music files are “rendered”, the resulting segment written by the composer contains all or parts of the following:
- A section playing at the original tempo and time signature
- A section where the tempo and time signature is changing over time
- A section with the final tempo and time signature
To accomplish tempo change in Wwise, the composer needs to:
- Separate these three sections in three different segments.
- Include the first and third segments in a Music Playlist Container inside a group set to “Sequence Continuous”.
- Create a new transition rule (in the Transitions tab of the Playlist Container) and insert the second segment (containing the tempo change) as a “Transition Segment” between the first and third segments.
This way, you can set a different tempo and time signature for the 1st and 3rd segment. The tempo and time signature of the 2nd segment becomes irrelevant since it is only possible to “leave” this segment (if a transition were to occur when the second segment is playing) at the “Exit cue”.
