TemperPlayer
TemperPlayer is a macOS player I built for listening to and inspecting a local music library. SwiftUI owns the application and workspace. Zig handles FLAC and WAV decoding, mastering analysis, and pitch processing behind a C ABI.
Implementation
I built the SwiftUI application, SQLite-backed library, queue and playlist flows, menu-bar player, waveform, spectrogram, and multiband goniometer. In Zig, I implemented FLAC and WAV decoding, mastering measurements, and an identity-phase-locked phase vocoder with transient resets and Kaiser-windowed sinc resampling.
The engineering work includes the Swift and Zig C ABI, real-time analysis, bounded visual queues, sample-rate handling, track-switch lifecycle, stereo phase correlation, and native macOS packaging.
