Audio How to measure dynamic range (in sense of dynamic compression/ loudness war)

1. How do you calculate dynamic range of audio?
2. Is loudness range same as dynamic range?
3. Does compression affect dynamic range?
4. What is dB in dynamic range?

How do you calculate dynamic range of audio?

The dynamic range for a specific audio file is therefore: the highest RMS value present minus the lowest representable, non-zero (-inf dB) RMS value. For example: 24 bit with 6 dB head room: -6 dB minus -144.5 dB = 138.5 dB Dynamic Range.

Is loudness range same as dynamic range?

The dynamic range is not relative to the loudness of your music, so if your music is over compressed the oscilloscope will turn red regardless of how quiet the track might be. A small dynamic range can come about from over compression and limiting.

Does compression affect dynamic range?

Compression reduces the dynamic range of a sound. It turns down the loudest parts of the sound while bringing the quietest parts up. This makes the volume more consistent but decreases the dynamic range.

What is dB in dynamic range?

Dynamic range describes the ratio of the softest sound to the loudest sound in a musical instrument or piece of electronic equipment. This ratio is measured in decibels (abbreviated as dB) units.
