When exact is False, it uses the gammaln function to obtain good precision without taking much time. Web-90° means the filter needs some lookahead before it starts working correctly. So an LPF will smear more of the top end, and a HPF will smear more of the bottom end. You can make zero phase filters with no phase smearing (because math) but they have huge latencies compared to normal filters because they need a lot of lookahead (because math.) radly streamer

WebThe notches on the comb filter will appear to “move,” resulting in a searing resonance that sweeps to the rate of the LFO. Flangers also make great use of feedback, sending the output back to the input to receive more processing. This accentuates the notches and resonances, resulting in the harsh, metallic timbre characteristic of flangers. ... WebComb filter example.

This means that there is … radlrast ansbachWebDifferential delay value used in each of the comb sections of the filter, specified as a positive integer. For details, see Algorithms.If the differential delay is a built-in integer data type, the decimation factor must be the same integer data type or double.For example, if the differential delay is an int8, then the decimation factor must be an int8 or double. radlwimmer

"WebWhen the signal is delayed by 50ms or more, it begins to sound like an echo. Time delays from less than 1ms to about 25ms create comb filter effects. Time delays beyond that range create an echo effect. Therefore, for the purposes of discussing comb filtering, we will be working with delay times in the 0ms to 25ms range. " - Comb filter math
