DSP Audio Effects Project
ABOUT
The goal for this project was to use digital signal processing to implement common audio effects. To do this we used DSP techniques learned in class, as well as additional techniques dealing with nonlinear processes. We utilized both live recordings of piano, clarinet, and guitar as well as professionally recorded songs in mp3 format to demonstrate our different effects. The examples we posted on this website were chosen because they most effectively demonstrate the changes caused by the processing. The Matlab code for all implementations of each effect is available to download from this site and can be used to edit audio files of various formats compatible with matlab.
APPLICATIONS
The effects we implemented are commonly used to enhance and manipulate sounds in music and can easily be combined to create complex and dynamic sounds. All of our implementations are designed to be used for post-processing rather than real time. This means our implementations can be used to edit music that has already been recorded. However, these same effects can also be produced for real time manipulation through hardware systems, such as effects pedals used for electric guitars.
