The Meridian interface, metering you can actually read.
K-weighting runs as two biquads per channel, a +4dB high-shelf at ~1682Hz and a 38.1Hz Butterworth high-pass, feeding Momentary (400ms), Short-Term (3s) and Integrated readings.
Integrated LUFS uses the actual BS.1770-5 gate sequence, a -70 LUFS absolute gate, then a -10 LU relative gate below the ungated mean, not a simplified single-pass average.
A polyphase-IIR oversampler at 4x catches inter-sample peaks a standard sample-peak meter misses entirely.
Smartphone Trap (mono-summed, 350Hz–6kHz bandpass), Streaming Penalty (auto-gains to your target LUFS, -23 to -6) and Bluetooth Transcode (-6dB HF shelf at 8kHz), all continuously smoothed so toggling never pops.
0 VU reference adjustable from -18 to -6 dBFS in 0.5dB steps, RMS-domain ballistics with a 300ms time constant, 3-second peak hold before decay.
Every control is automatable and plainly named. No hidden presets.
