2.8 Warmth
The WARMTH process confers additional loudness, punch and definition to the sound of the
dynamics section. The operation of this process is to impose a harmonic profile onto the
signal that increases the density of higher value samples within the programme, in order to
boost average modulation levels without an increase in peak levels or the risk of digital
clipping. The Warmth function is engineered to achieve this without the loss of dynamic
information within the programme material.
Another very important purpose of the Warmth function is to accommodate internally
generated levels up to 6dB greater than notional digital maximum, without causing increased
peak levels or hard clipping. The main advantage is that short term level peaks and
overshoots, resulting naturally from the artistic use of compression, can still provide
harmonic information to the programme even though they may represent levels above
maximum digital modulation, that would be subjected to hard clipping if left untreated.
