v1.7.0 — Normalize + .pkg installer
What's New
Normalize
Loudness normalization with preset targets:
- -14 LUFS (streaming — Spotify, Apple Music, YouTube)
- -16 LUFS (podcast / spoken word)
- -23 LUFS (EBU R128 broadcast)
- Custom target
Output saved as filename_-14LUFS.ext alongside the original.
.pkg installer
The DMG now contains a .pkg installer instead of a raw .workflow file. This fixes the Gatekeeper block on macOS Tahoe — no Terminal commands needed.
Safe mono conversion
Mono downmix now uses explicit 0.5 channel coefficients — mathematically cannot exceed the original peak level, regardless of channel correlation.
Dual-mono detection
Stereo files with identical L/R channels are flagged in the analysis report.
Install
Download the .dmg, open it, double-click the .pkg, follow the prompts.
Security note
macOS may warn that this installer is from an "unidentified developer." This is expected — the package is not signed with a paid Apple Developer ID certificate, not because anything is wrong with it. The tool is fully open source — you can read every line of code before installing. To proceed: right-click the .pkg and choose Open, or go to System Settings → Privacy & Security → Open Anyway.
