While not perfect, I really liked Will Pirkle’s book[1]. It describes the popular ABIs and has great intro to DSP. I would say the downsides are that the description of various interfaces takes up too many pages and that the book uses his own framework ASPiK for cross-compatability, but it’s easy enough to convert to a more popular framework like JUCE if needed.
