Rekordbox to CDJ prep toolkit - loudness gain, Key+BPM playlist sort, and CDJ-safe MP3 transcode

Bake'n Deck (baken) is a Rekordbox to CDJ prep toolkit, the successor to headroom (renamed at v3.0.0). The headroom subcommand analyzes audio files for loudness (LUFS) and True Peak headroom, then applies lossless gain adjustment. It supports MP3, AAC/M4A, FLAC, AIFF, and WAV files, with batch processing, lossless MP3/AAC gain via mp3rgain, and a scriptable non-interactive CLI mode. The rbsort subcommand sorts a Rekordbox collection.xml export by Camelot Key and BPM for harmonic mixing prep - no audio touched, no ffmpeg required. The cdjsafe subcommand (new in v3.0.0) converts every track in a playlist to 320 kbps CBR MP3 at 44.1 kHz for pre-NXS2 CDJs, emitting an updated XML in which converted tracks inherit beatgrids and cue points verbatim.
