(compMus2) Convolution
Convolution is a fundamental process in digital audio processing. Even if you do not specifically know that the process is happening, you know the effects of the process. Filtering, reverberation, and cross synthesis all illustrate convolution. For example, a filter convolves its impulse response (IR) with the input signal to produce filtered output. Sampling reverbs convolve…

The number of sine waves needed could be infinite, and each sine wave would have its own frequency, amplitude, and initial phase. The process of calculating the frequencies present in…
