4.8 Compressor Timing Laws
The Oxford compressor offers three compression types designated
NORMAL, CLASSIC
and
LINEAR, selected sequentially via a button in the centre of the Dynamics display. The
time constant laws employed define the major difference between these types.
The Oxford Dynamics uses both Exponential dB/time and Linear dB/time laws as
illustrated below:
Exponential/dB curve used in Normal and Classic types
Linear/dB curve
The Oxford Dynamics time settings are displayed as real time constants when in
exponential mode. In linear mode the display is scaled to correspond to the time required
for a 10 dB change of level. This provides a degree of parity between the perceived
timings of the two laws, which facilitates comparison and selection between compression
types. These two laws have very different sonic characteristics.
