From EE Times:
Guitarists usually associate digital signal processing with electric, rather than acoustic, guitars, especially after early attempts to apply DSPs to acoustic instruments led to modeling effects that kept the guitars from performing as advertised.
Now Fishman Transducers Inc. says it has repurposed the Analog Devices Inc. Blackfin DSP to perform "digital acoustic imaging" instead of modeling, making acoustic guitars with an inexpensive piezoelectric pickup sound as if they were in a pristine studio in front of an expensive condenser microphone.
"When we first considered digital signal processing for guitars, we were just thinking modeling--making a Gibson sound like a Fender," said Larry Fishman, president of Fishman Transducers (Wilmington, Mass.). "We tried that, but found that it's much too complicated a problem, with all the subtle complexities. Now what we do instead is make an acoustic guitar sound as good in your home recordings, or live onstage, as it does in a professional studio."
The idea, he said, "is to capture that great studio sound and bring it out to real world of performances."
