I like this but it's pretty beginner, learned something though!

My suggestion is to first focus on understanding Sanskrit phonology (Shiva Sutras) and learning to read the Devanagri script.

The "Mother Tongue" video series by Dr. Anuradha Choudry linked below (not available on Youtube) is an excellent resource; I signed up for a free trial recently and honestly I'm blown away by the quality of the content (I've no affiliation; this is just my recommendation):

In particular, both "The Sound of Sanskrit" & "Sounding and Seeing the Consonants" series.

Also see the Maheshwar Sutras by Achyut Karve (think of the Shiva Sutras as an ancient IPA but far more natural) - https://www.youtube.com/watch?v=yGy7f4WhKjU
