LOUDNESS METER
ARMETER is a transparent audio metering plugin that measures loudness, true peak, frequency content, and stereo behavior without processing the signal. Audio passes through unchanged, with sample-for-sample input and output verified on every build. Loudness measurement follows ITU-R BS.1770, providing 400 ms momentary, three-second short-term, and gated integrated readings alongside loudness range and true peak in dBTP. Its K-weighting filter coefficients match the published standard values to machine precision. A logarithmic spectrum analyzer with optional peak hold provides frequency feedback, while correlation and side-energy displays help assess the stereo image and identify potential cancellation. The display automatically stops updating when no audio is playing.
What ARMETER offers
EBU R128 Loudness Metering: Monitor momentary, short-term, and gated integrated loudness
