• 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 - particu-
larly 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 AMM-1’s models do model variations in transient
response in both directions.
Rather than explain how this is done (which we are disinclined
to do, anyway), we suggest that you demonstrate it to yourself
with the following experiment:
1. In a computer-based waveform editor, use the Pencil Tool (or
equivalent waveform drawing tool) to create a single high-
amplitude spike.
2. Process this file through the AMM-1 with the Source Mic set to
Bypass (so the spike is passed through the Source section un-
changed) and the Modeled Mic set to the ATM31.
3. Examine the processed signal in the waveform editor. You
should see obvious evidence of the smeared transient.
