MUMT 307: Week #6

There are numerous applications in music technology that make use of frequency-domain processing to achieve a desired result. We investigated one example, additive synthesis, in the last class. The actual implementation of additive synthesis techniques is typically performed using the IFFT (the resynthesis), whereas the estimation of sinusoidal parameters is often performed using the FFT or STFT (the analysis phase). Developing a complete understanding of the relationships between time- and frequency-domain versions of a signal often involves advanced mathematics and courses in signal processing. In this section, we will develop a more intuitive insight into these relationships.
