7 – Appendix

be a problem when your source mic has a substantial bass or treble roll-off and the modeled mic has a corresponding boost or, more likely, when your audio was recorded with a low-cut filter on the source mic and you do not use a low-cut on the modeled mic. In both of these cases, the models will apply substantial gain to the affected frequency ranges, raising the level of added noise along with the desired signal. If the resulting noise level is unacceptable, you should choose a different combination of mics and/or turn on the modeled mic’s low-cut filter.

•• Transient Response One of the key characteristics of various types of microphones is their transient response (i.e., the way that their diaphragms respond to extremely rapid amplitude fluctuations, typically during a sound’s attack phase).

Intuition would suggest that modeling changes in transient response between mics would be next to impossible — particularly changing a source mic with a slow response to a modeled mic with a fast response. Amazingly, that turns out not to be the case. The TA‑1VP’s models do model variations in transient response in both directions.
