◉ AIRWAVE — RECEIVE-SIDE DIAGNOSTIC

Measures the actual audio you hear from the live X Space, right in your browser — on any device (tablet, Galaxy S25, laptop). It reads the stream read-only and never touches the broadcast, so unlike a server-side probe it can't degrade the audio. It shows the numbers in a corner overlay and auto-streams them to the station (via a tiny relay tab it opens), so the operator can tune the sound against what you actually hear — no screenshots needed.

Best on Mises / Android: install the one-tap extension — it auto-reports with no relay tab or pop-ups.

1 · Get the tool

Desktop: drag this button to your bookmarks bar:

▸ awmon

Phone / tablet (Chrome, Samsung Internet, Mises): you can't drag, so make a bookmark by hand:

  1. Bookmark any page (tap ⋮ → ☆).
  2. Open your bookmarks, Edit that one.
  3. Set Name = awmon, and replace the URL with the code below (Copy it first):

2 · Run it on the Space

  1. Open the X Space in the same browser and make sure it's playing audio in that tab.
  2. Desktop: click the awmon bookmark.
    Phone/tablet: tap the address bar, type awmon, and tap the bookmark suggestion that appears (tapping it from the bookmark list just reloads the page — the address-bar suggestion is what runs it).
  3. A small ◉ AIRWAVE MON box appears in the corner with live numbers, and a relay tab ("AIRWAVE RELAY") opens — leave that tab open; it forwards your readings to the station. Overlay should say "reporting → VPS". Tap/run awmon again to stop.

First run may ask to allow pop-ups for the relay tab — allow it. If it says "no live audio stream on this tab", start Space playback and run it again.

3 · Live readings — from every reporting device

Note: from an X Space tab, X blocks auto-reporting to this page — read the numbers off the corner overlay instead and screenshot them. This panel only fills in if readings can be posted (e.g. a non-X page or the operator's own tools).

RMS is loudness in dBFS (closer to 0 = louder; healthy program ≈ −20 to −14). low/mid/hi/air are 0–255 energy in 60–250 Hz / 250 Hz–2 kHz / 2–8 kHz / 8–16 kHz.
