A collection of professional audio-level metering plugins in LV2 format for digital audio workstations.
meters.lv2 is a collection of LV2 audio plugin meters that provide professional-level audio signal monitoring and analysis tools for digital audio workstations. It includes various meter types such as needle meters, bar-graph meters, spectrum analyzers, and specialized tools like EBU R128 loudness meters and goniometers. The project solves the need for accurate, standards-compliant audio metering within open-source audio production environments.
Audio engineers, music producers, and broadcast professionals who use LV2-compatible digital audio workstations like Ardour or Qtractor and require professional metering tools. It's particularly valuable for those working on audio mastering, broadcast compliance, and detailed signal analysis.
Developers choose meters.lv2 because it offers a comprehensive set of professional audio meters in a free, open-source package that implements international standards like IEC, EBU, and DIN. Its unique selling point is the combination of traditional needle meters with modern digital analyzers like true-peak and spectrum analysis, all with interactive GUIs designed for practical workflow integration.

Includes a wide range of meters from needle and bar-graph to specialized analyzers like EBU R128 and goniometer, covering multiple international standards as detailed in the README.
Supports click-and-drag calibration for needle meters, scalable interfaces, and peak-hold reset, enhancing usability in audio workflows with practical controls.
Implements IEC, EBU, DIN, and other professional audio standards, ensuring accurate metering for production, mastering, and broadcast as highlighted in the features.
Freely available under an open-source license, providing professional-grade tools without licensing costs, ideal for budget-conscious studios.
Requires compilation from source with specific dependencies like LV2 SDK, libcairo, libpango, and openGL, and recent versions for threading safety, which can be daunting for non-technical users.
Only works with LV2 hosts that support resize-port and idle-interface (LV2 SDK >= 1.4.2), excluding some DAWs and potentially limiting integration.
The README warns that older library versions (pre-2013) are not thread-safe, which could cause crashes or instability in multi-threaded audio hosts.
