TapeDither Redux

I thought I had it all worked out. Put out a proper, well-coded TPDF dither, the highpassed variation on it I've called PaulDither, and move on to the fancy boutique stuff. But there was this one experiment I had in mind. If you could do the highpass by delaying and then subtracting the random noise (and it gained you a bit of efficiency in the bargain), why not delay it more? It'd create comb filtering, a cancellation node. Why not keep delaying until the cancellation node dropped right down to around 1.5K? Surely this would give me a nice cancellation notch right where the ear is most sensitive, and heightened clarity. What could go wrong? Nope! I made a prototype, called it 'NodeDither', began experimenting, and immediately found that I'd made… a flanger! The long delay settings were useless. It made obvious overtones just out of the dither noise, a blatant tone color cast that wouldn't produce the desired effect. It didn't even produce an obvious notch in the response where I wanted it. The only thing it did do, was continue to function as a working TPDF dither no matter what the setting was (more on this later). But, something else turned up in the experiments, and that's what brought you TapeDither. http://www.airwindows.com/tapedither-redux/ http://www.airwindows.com/airwindows-nodal-tempo-guide/ https://www.patreon.com/airwindows/
