Tagalog is an Austronesian language spoken as a first language by a quarter of the population of the Philippines and as a second language by the majority. Its standardized form, officially named Filipino, is the national language of the Philippines, and is one of two official languages alongside English.
IU doesn't offer Tagalog currently. But you could find two audio files here that might be helpful for your learning. You could find free or charged learning material on Duolingo, Mango Languages or Rosetta Stone.
