Audio Meters

See what you hear. Nine studio meters on your keys and dials.

Level, VU, spectrum, spectrogram, waveform, oscilloscope, stereo field, loudness and musical key. There is no driver to install and no account to make. On Windows it reads the system's own loopback capture, the same way a screen recorder hears your PC; on a Mac it uses Core Audio's own process taps. Play something and it moves.

Listen to exactly what you want

Everything your computer plays

One output - your speakers, your headphones, a second device

One input - a microphone, a line-in, or your interface's own loopback

One app - only Spotify, only the game, only the browser

One press puts the same source on every meter on every page.

Every meter goes deeper

Level: peak and RMS, sample or true peak, peak hold and a CLIP lamp that waits for you

VU: needle, twin needle, bar or LED, with 0 VU at -20, -18, -14 or -12 dBFS

Spectrum: 12 to 56 bars with peak caps

Spectrogram and waveform: frequency and amplitude over time, at the speed you set

Stereo: polar or Lissajous, with correlation

Loudness: momentary, short-term, long, integrated, max, range, true peak and PLR, against your own target

Key: note names or Camelot, with a confidence bar

On a Stream Deck +, turning the dial steps each meter's own setting and a press resets it.

A DAW on ASIO, too

Windows never hears ASIO. Point a meter at your interface's hardware loopback and the DAW shows up with everything else. Tested on an Arturia MiniFuse; the Focusrite route is in the manual.

It never moves on nothing

Silence says QUIET. A closed app says APP NOT RUNNING. A muted output says MUTED. A face that cannot know something says so, rather than drawing a bar that dances on air.

Six palettes, including the shared Firedies color taken from the album cover of whatever is playing, or two colors of your own. Alert red never changes.

Audio Meters is also part of Firedies Complete: all seven Firedies plugins in one, with the same features as each on its own. Until 30 November, Complete is 20% off with code FIREDIES20.

Windows 10 or later, and macOS 13 or later. On a Mac, listening to the system, an output or a single app needs macOS 14.2; an input works on any version.

A tenth meter, loudness standards, a mic that follows your system, and meters that ask far less of your computer.

New in 1.2.0

4-Band Split: a DJ-style waveform with lows, two middles and highs each in their own color, as Mirror around a centre line or Overview standing on the floor. Firedies colors, or four shades built from any palette or album cover

Loudness standards: Streaming, Amazon, Apple, Deezer, EBU R128, ATSC A/85, Netflix and Loudness War, or your own. Each sets the loudness target and a true-peak ceiling, and Level draws the ceiling

Default input: a meter can follow whichever microphone your system uses, and says NO MIC when there is none

Mark clipping in red, off by default: a clipped moment turns red where it happened, and a dot by the title stays lit until you press

Improved in 1.2.0

Meters now take a fraction of the processor. Ten meters running together use about a fifth of what they did, at the same frame rates, and every face looks exactly as before

A new meter shows its source name from the start

Fixed in 1.2.0

Fixed bug where a meter's own source switched back to the one set with "Use this source on every meter" after Stream Deck restarted. A meter whose source you changed afterwards now keeps it.

Your sources, meters and settings carry over as they are.z
