## Comentarios

Esta estructura la usan los comandos `ACP_COMMAND_UPDATE_CONTEXTS` y `ACP_COMMAND_UPDATE_ALL_CONTEXTS` para actualizar un único contexto de EQ/Comp. Use el comando para actualizar solo un número pequeño de contextos por fotograma de audio; actualizar un gran número de contextos no es eficiente. Para obtener más detalles, consulte la [sección Representación de audio de Información general sobre ACP](/build/console-features/audio/overviews/acp-overview#ID4E6C).

Esta estructura también incluye métodos insertados:
