Calculator cluster
Signal, cables & storage
HDMI bandwidth, cable capacitance, audio delay, Plex storage and STC estimates.

Audio Delay Time Calculator
Convert a path-length difference into milliseconds and 48 kHz samples for DSP speaker delay.

Audio Cable Capacitance / Treble Loss Estimator
Model a long RCA/XLR run as an RC low-pass: f-3dB and loss at 20 kHz from pF/m, length and source impedance.

HDMI Bandwidth Calculator
Estimate video Gbit/s from resolution, refresh, bit depth, chroma and blanking. See if HDMI 2.0 TMDS (~14.4) or 2.1 (48) is enough.

Plex / Media Server Bitrate to Storage Size
Convert video bitrate and hours of library into gigabytes and terabytes. 1 Mbit/s for 1 hour is 0.45 GB.

Soundproofing STC Estimator
A mass-law-ish STC estimate from surface mass and an air gap. Higher STC, quieter neighbours — bass still leaks.
