Hi everyone,

I'm the developer behind Audivea, and I've just released my first plugin — Arcoline, a free metering suite for the final delivery check. The idea was to stop juggling three or four separate meters before an export and read the whole picture in one window, at whatever level of detail you need.

Two views, switchable with Tab:
Dive — the full workbench, every reading at once.

Ascend — a stripped-back at-a-glance readout: one big Integrated-LUFS number and a ±LU delta against your target, for a quick "am I safe to deliver?" check.

What it measures
- Loudness — Momentary / Short-term / Integrated LUFS, ITU-R BS.1770-4 K-weighting
- True peak — inter-sample dBTP via oversampling, with a sticky over-flag so a stray transient can't slip past
- Level — per-channel peak & RMS, peak-hold, clip detection
- Dynamics — PSR, PLR and loudness range (LRA)
- Stereo image — goniometer, phase correlation and L/R balance
- Tonal balance — low / mid / high energy split
- Delivery targets — built-in presets for Spotify, Apple Music, YouTube, broadcast and film

Three themes — Deep Blue, Neutral Dark, Light:

Price: Free — no account, no email wall

It's version 1.0 and I'm actively working on it. I'd really value this crowd's feedback — especially whether the Ascend view delivers the "one glance and you know" read it's aiming for, and whether the target presets match how you actually deliver. Thanks for taking a look!
