attack, especially to provide adequate control of certain vocal styles,
and the usual consequence that the whole vocal phrase then suffers
from over compression. It is often difficult to achieve the attack
speed without the undesirable over compression.
The P1 compressor achieves this by altering the ratio of the
compressor dynamically. So you can set an average compression
ratio on the front panel control but the actual delivered ratio will alter
to suit the dynamics of the audio as it rises above the threshold level.
These principles are at the heart of the peakride design and are
achieved by mixing the three compressor side-chains at different
levels and with different compression ratios. In effect, the
compressor side-chain is able to ride the peaks of the audio, reacting
quickly but smoothly to fast attack peaks, and then able to track the
dynamics of the continuing audio till it falls below the threshold point.
