Abstract
Instrument amplification systems incorporating reflection cancelling boundary microphones and multiband compression in accordance with embodiments of the invention are disclosed. In one embodiment, an amplification system includes a microphone configured to generate an audio signal based upon acoustic waves within the instrument including audio content within a low frequency band including a fundamental resonant frequency of the instrument, a middle frequency band including at least one harmonic frequency of the instrument, and an upper frequency band, where the frequency response characteristics of acoustic waves generated within the instrument in the low frequency band differ from the characteristics of acoustic waves generated outside of the instrument, and an electronic preamplifier system configured to provide the audio content within the low frequency band to a low frequency band amplification circuit that applies compression to provide audio content having frequency characteristics corresponding to the characteristics of acoustic waves generated outside of the instrument.
