How to intercept Post Title on Post-Save

To set the title before it is saved, hook into wp_insert_post_data:

add_filter( 'wp_insert_post_data', 'wpse_75597_change_title' );

function wpse_75597_change_title( $post_data )
{
    $post_data['post_title'] = 'SOMETHING VERY LOUD';

    return $post_data;
}
