Upsampling for data balancing is also distinct from upsampling in image processing. In the latter, high resolution images are first reduced in resolution (removing pixels) for faster computations, after which convolution returns the image to its original dimensions (adding back pixels). The latest AI...
I thought I would put a “how to read this chart” legend as the other charts are easier to read (i.e. mostly we want a straight line ☺ There is a concept ofpreringingwith linear phase filters, so we want to watch for this type of distortion, even though in listening tests I h...

Convolutions in the time domain are equivalent to multiplications in the frequency domain, i.e., given two signals x(t)x(t) and y(t)y(t), then if z(t)=x(t)⋆y(t) z(t)=x(t)⋆y(t) where ⋆⋆ denotes convolution, then the Fourier transform of z(t)z(t) is merel...
