While use of ASIO and IM effects can allow the use of effects in realtime, in this particular instance, that of a vocalist with wide dynamic range, it won't provide protection against overloading the input analog circuitry nor the A-to-D of the soundcard because the plugin only works on the digitized numbers and not on the actual real signal.

The way to record the vocalist is either straight in with lowered input gain such that the loudest part sung will not push to 0dB clip point, getting the gain back after the fact with the gainchange algorithm plugin if need (or pgdynamics compressor plugin or a combination of the two) OR -- place a hardware compressor unit adjusted accordingly in series between the mic and the soundcard input. Set the compressor up as a soft Limiter only. Insurance.
