au / aw usually represent the same long vowel /ɔː/ (sometimes closer to /ɑː/ in American English). au appears often in initial or medial positions, while aw is common word-finally.

Word Analysis

audit /ˈɔːdɪt/: stable long vowel at word onset; augmentation /ˌɔːɡmenˈteɪʃən/: stressed au stays long; autobiographic /ˌɔːtoʊ-/: auto- keeps /ɔː/ quality.

Pitfalls

Do not confuse with /aʊ/ as in out; aw is not /æ/; note accent variation but consistent back-vowel logic.
