AI Analysis

●●SolidCozyBig Brain

Core Audio process tap workaround for Spotify DRM is genuinely clever engineering.

Strengths
  • •Muted-when-tapped process tap captures Spotify audio without virtual devices
  • •Per-song key memory with menu bar UI that never shifts layout
  • •Local build avoids notarization and unidentified developer warnings
Weaknesses
  • •Requires macOS 14.4+, limiting audience to recent Mac users only
  • •Vocal reduction feature is experimental and works inconsistently

Custom ML model – if Spotify was instrumental

This ships a tidy, browsable library of on-demand vocal removals backed by a custom 'BiMamba UNet' trained on a curated ~500-song dataset — the interface actually feels built for music discovery rather than a bare demo. Don't expect SOTA separations (the author trained on one A40 for days and is honest about limits), but the vibe-coded dataset and integrated conversion pool make it a fun, useful tool for quickly grabbing instrumentals.
