DSP equalization of electret film pickup for the acoustic guitar

The response of a guitar bridge pickup does not correspond to the acoustic radiation of the instrument. Digital signal processing is applied to obtain high-quality acoustic sound using only an elastic electret film pickup and properly designed digital filtering for equalization. The most promising r esults are obtained with long FIR filters with possibly one or more body re sonances modeled with separate digital resonators, or with warped IIR filte rs.
