Configuring a device to accurately represent a known value.
- Calibrated monitoring involves measuring the loudness of your speakers with an SPL meter and ensuring that work is done at a known volume level. For instance, film mixing studios have monitor systems calibrated so that pink noise at -18 dBFS produces 85 dbSPL at the listening position.
- Meter calibration ensures matching gain structures between analog and digital devices. For instance, professional audio line level (+4 dBu) should produce an analog meter reading of 0 VU and a digital meter reading of -18 or -20 dBFS.
