Respuesta:
Como sugiere @fuxia, también debe extender la verificación $wp_filetype para mp3. para la extensión de mp3, puede utilizar audio/mpeg3, audio/x-mpeg-3, video/mpeg, video/x-mpeg . simplemente agregue la condición de verificación en el bloque de try donde verifica el tipo válido de imagen. Lo he probado y me está funcionando bien. avíseme si esto le ayuda.
if ( !substr_count($wp_filetype['type'], "image") && !substr_count($wp_filetype['type'], "audio")) {
throw new Exception( basename($imageurl) . ' is not a valid ' . $wp_filetype['type'] . '' );
}
