WebJun 25, 2003 · Hi Gustave, you want an allpass with modulated order? That's a real challenge! ;-) It could be done with cascaded allpasses and setting the amount needed to "passive" (pole(s) @z=0, zero(s) @z=inifinity <= that is the main problem !!). The other way is to tap a filter-cascade ... maybe with crossfade ...

An all-pass filter is a signal processing filter that passes all frequencies equally in gain, but changes the phase relationship among various frequencies. Most types of filter reduce the amplitude (i.e. the magnitude) of the signal applied to it for some values of frequency, whereas the all-pass filter allows all … See more A common application in electronic music production is in the design of an effects unit known as a "phaser", where a number of all-pass filters are connected in sequence and the output mixed with the raw signal.

WebOct 31, 2016 · In reverbs, you get a thing called an allpass filter (a kind of feedback delay at a specific calibration) which diffuses the sound so it can be fed to delay banks and seem more spatial. Turns out these are the same basic thing. It's also in phase shifters (mixing the phase-shifted part against dry, or inverse dry). What happens?

WebOct 22, 2024 · An allpass filter is a filter with a unity gain across all frequencies. This means that no frequency passing through that filter will be boosted or attenuated. It introduces, however, a frequency-dependent delay.

WebJun 18, 2024 · Using an allpass loop, or a feedback delay network with fewer branches but more density in each branch, is a good idea in this case. Having said this, there is a generalized matrix representation of reverberation structures, where you have separate matrices for the inputs (feedforward), the feedback between the delays, and the outputs. WebNov 8, 2016 · The all-pass filter is a phase manipulator—you can selectively adjust the phase of the signals passing through the filter without altering the amplitude. All-pass filters are used in circuits referred to as “phase …

WebAllpasses are probably the most underrated filters and can be a lifesaver in automotive sound. Although they do not affect the spectrum, they affect the phase of the processed signal. This can be helpful on midrange and midbass channels to make staging and integration perfect, when delay in just a certain frequency band is needed.
