Luis Andrade fell down the codec rabbit hole while studying Audio Engineering at Full Sail University, eventually publishing a senior thesis on psychoacoustics and streaming bitrates. He spent four years on the user-experience team, fine-tuning interface labs and dark-mode rollouts. Now freelancing from São Paulo, he still A/B tests updates across six devices before writing. Luis’s tutorials demystify playlists, palettes, and hidden tweaks so listeners squeeze every drop of sound and style from their apps.
