如果ashortcode 您可以使用它来构建用于嵌入的soundcloud url，这并不太费劲。

add_shortcode(\'soundcloud_auto\', \'soundcloud_auto_shortcode\');

function soundcloud_auto_shortcode($atts) {
    global $post;

    $title = str_replace(" ", "", $post->post_title);
    $title = str_replace("-", "", $title);
    $title = str_replace("_", "", $title);

    $slug = sanitize_title($title, str_replace("-", "", $post->post_name));

    return wp_oembed_get(esc_url("http://soundcloud.com/$slug"));
}

add_filter(\'the_content\', \'add_soundcloud\');

function add_soundcloud($content){
    global $post;

    $title = str_replace(" ", "", $post->post_title);
    $title = str_replace("-", "", $title);
    $title = str_replace("_", "", $title);

    $slug = sanitize_title($title, str_replace("-", "", $post->post_name));

    return $content . wp_oembed_get(esc_url("http://soundcloud.com/$slug"));
}
