Could you build this?

Partial While basic podcast playback and RSS feed parsing are vibe-codeable, building low-latency custom DSP audio algorithms (dynamic voice boost, real-time silence skipping) and reliable watchOS sync requires specialized audio engineering.

What it would actually take: A production version requires Swift, SwiftUI, AVFoundation, and CoreAudio/AudioUnits on iOS and watchOS. The complex parts include implementing real-time DSP filters for voice clarity and artifact-free silence truncation (smart speed) during variable-rate playback, as well as background audio session management and companion device state synchronization. This demands specialized native iOS audio engineering skills.
