Sound processing tricks in Flutter that you MUST TRY | Andrii Khrystian

Live from FlutterCon USA in Orlando, Craig sits down with Andrii Khrystian, software engineer at Dynatrace and former physics student, to break down the mechanics of audio processing in Flutter! In this interview, Andrii explains why audio processing relies heavily on native C-libraries like FFmpeg, demonstrates a live voice-changing Flutter app, dives into frequency manipulation, pulse-code modulation (PCM), and shares tips for post-processing audio effects in mobile apps.
