Overview
Barometer is a precision metering and gain staging utility. It passes audio through with zero latency while providing LUFS, true-peak, and dynamic range measurements alongside essential utility controls.
Interface Layout
Metering Display
The central area shows real-time loudness meters: integrated LUFS, short-term LUFS, momentary LUFS, true-peak levels (L/R), and loudness range (LRA). All measurements follow ITU-R BS.1770-4.
Utility Controls
Gain, phase, balance, width, mono, swap, DC filter, and output trim. These let you prep your signal for delivery without leaving the metering view.
Signal Flow
Audio flows through Barometer in this order:
Input Gain adjusts the signal level entering the chain. Range: -96 dB (mute) to +24 dB.
DC Filter is a 5 Hz high-pass filter that removes DC offset — common in some analog hardware chains and certain plugin interactions.
Phase inverts polarity on L, R, or both channels (when linked). Essential for checking phase coherence in multi-mic setups.
Mono / Width controls stereo width from 0% (mono) to 200% (widened). The Mono button forces a mono sum for compatibility checking.
Balance shifts the stereo image left or right (-100 to +100).
Swap exchanges left and right channels.
Solo L / Solo R isolates a single channel for independent monitoring.
Output Trim sets the final level after all processing (-12 to +12 dB).
