/** Audio Performance mode.
 * Performance mode tells the framework how to configure the audio path
 * for a player or recorder according to application performance and
 * functional requirements.
 * It affects the output or input latency based on acceptable tradeoffs on
 * battery drain and use of pre or post processing effects.
 * Performance mode should be set before realizing the object and should be
 * read after realizing the object to check if the requested mode could be
 * granted or not.
