What's New

Every update, in one place

v0.2.0Oct 31, 2026Latest

Cover art, right-click and shareable templates

The queue now looks like your library, every row has a menu, and a template is a file you can send to someone.

  • Album art shows next to every file in the queue.
  • Right-click a row to play it, reveal it, copy its path, re-analyze it or drop it.
  • Export a template to a file and import one back. No account, no sign-in.
  • A short tour on first launch, reopenable from the title bar.
  • Dark and light themes rebuilt for readability: no more unreadable greys or dimmed-out fields.
  • Version and a support link now sit along the bottom of the window.
v0.1.0Oct 31, 2026

First release

Drop in a folder of finished tracks and get them back at one consistent volume, with clipped peaks repaired and the tags still on them.

  • Everything you process lands on the same loudness target, with a true-peak limiter so nothing distorts on the way there.
  • Clipped peaks are repaired before anything else touches the file.
  • Tracks sitting off concert pitch can be corrected, keeping the tempo or moving it with the pitch.
  • Optional warmth and multiband dynamics, saved into named templates you reuse.
  • Reads the formats a library is actually made of, writes AIFF, WAV, FLAC, ALAC or MP3, and carries your tags across.
  • Your originals are never touched: processed files are written somewhere new.
