Acoustic sound from the electric guitar using DSP techniques
Matti Karjalainen, Henri Penttinen, Vesa Välimäki · 2002
The electric guitar has been developed to withstand electric amplification and utilize (mostly analog) signal processing in order to create a multitude of timbres and sound types. Sometimes it would be desirable to play the same electric guitar, yet with a sound that resembles a good acoustic guitar or some other member of the plucked string instrument family. In this study we have investigated DSP techniques that can be used to shape the magnetic pickup output of the electric guitar to simulate acoustic instruments. This includes linear filtering for body simulation, time-varying modulation to generate beating of the harmonic components, and techniques to simulate the general temporal envelope of the plucked notes.
