OpenMeters is an audio metering and visualisation application for Linux. It captures audio through PipeWire and provides detailed, real-time information about loudness, frequency content, waveforms and stereo characteristics.
The application is designed for musicians, audio engineers and anyone interested in analysing sound. It combines several complementary visualisation tools in a configurable interface, allowing users to examine different aspects of an audio signal simultaneously.
OpenMeters can monitor individual applications or audio devices. Its visualisations can be rearranged, displayed in separate windows or combined into a compact bar along the edge of the screen on compatible Wayland compositors.
The software supports both Wayland and X11 desktop sessions, with hardware-accelerated rendering through Vulkan or OpenGL.
This is free and open source software.
Key Features
- Captures audio from individual PipeWire applications, devices and default audio outputs.
- Supports audio devices with channel layouts of up to eight channels.
- Loudness metering with momentary and short-term LUFS measurements, true peak levels and fast or slow RMS measurements.
- Oscilloscope with selectable audio channels, zero-crossing triggering and stable waveform tracking.
- Spectrogram with short-time Fourier transforms and time-frequency reassignment for improved frequency resolution.
- Provides musical note and frequency tooltips, a piano-roll overlay and frequency-axis zooming and panning.
- Spectrum analyser with configurable frequency scales, A-weighting, exponential averaging and peak hold.
- Supports line and bar spectrum displays with adjustable colour maps.
- Stereometer with Lissajous and dot-cloud displays for examining stereo imaging.
- Includes single-band and multiband phase-correlation measurements, with configurable time windows.
- Waveform display with adjustable scrolling, channel selection and optional frequency-band history overlays.
- Supports left, right, mid and side channel selection in compatible visualisation modules.
- Configurable display layouts with detachable visualisations and adjustable refresh rates.
- Wayland bar mode positions visualisations along the top or bottom of a monitor on compatible compositors.
- Customisable colour themes, background transparency and persistent application settings.
