PKD COMPRESSOR

The six plots here are graphs of three audio signals in both the time and frequency domains. We analyzed the frequency content so that we can compare the results after we have created a functional compressor. We tried to get tracks of different harmonic and rhythmic content to test the different effects our compressor will have.

 

Plotting these audio files using Matlab posed some difficulties, as we had to figure out how to plot them in a way that made sense for audio. This was alleviated after some research into plotting commands and the FFT operations in Matlab.

 

We recorded the tracks using microphones, preamps, and AD/DA converters in the Audio Studio in the Duderstadt Center. The performer is a singer-songwriter and jazz musician named Rachel Mazer.

 

We have been researching a C++ library called JUCE that facilitates audio processing and plug-in building. This will hopefully allow us to create a standalone application that can both process audio in real-time and be put into a .vst or .au format to be integrated into a Digital Audio Workstation (DAW).
