MIC REPLACEMENT SECTION
The Mic Replacement section is Mic Group specific, meaning that original and replacement
Mic selections only affect the currently selected Mic Group.
Different microphones have different sonic characteristics. Microphones come in different
quality levels and they also have different directional characteristics (Omni directional,
Cardioid, Wide Cardioid, Hyper Cardioid, Figure 8…), They may also give different responses
according to the pitch or timbre of the source audio. To cover all these possibilities, GigaPulse
includes a generous selection of Microphone impulse models. You can use these to remove the
characteristics of one microphone and replace it with the characteristics of another.
Experimentation can lead to unique and interesting results.
Note: Using original (inverse) and/or replacement mics (as well as Pattern and Filter
selections) will cause GigaPulse to pause and run a short calculation when the mic models are
chosen, but they do not require additional CPU when processing audio.
Original Mic: This drop-down menu provides a list
of microphones that might have been used in the
original recording being processed by GigaPulse. By
selecting the appropriate mic, you apply the inverse
impulse response, which effectively removes the
character of the selected mic model from the original audio. This is why (inv) is at the
beginning of these choices.
Replacement Mic: This drop-down menu provides a
similar list as the Original Mic list, but these
microphones are used to apply the character of the
selected mic model that will effectively replace the
original.
It is important to understand that the matching a microphone is not an absolutely perfect
process. The impulse characteristics employed by GigaPulse are those of good condition,
unmodified models, and there may be variations according to age and wear. The match should
be fairly close in most cases though.
