> “Filters are delays” doesn’t imply “delays are filters”. Purely logically, no, but that's not really the practical sense we're talking about. And by introducing a digital delay, you do induce a filter on the sound. So if you have a delay, then you have a filter. > In particular, the type of effect known as a delay (e.g. a delay guitar pedal) isn’t a filter, certainly not in the musical sense, which is the relevant sense here. I think it's best to reconsider my original comment. I was arguing that it isn't useful to suddenly rename subtractive synthesis as a "transformation", because you could just rename all of synthesis "filtering". But that's not useful, and synthesis just means building up sound from parts. I.e., it's best to work at a given level of the parts and think about things like waveforms, envelopes, LFOs, pulses, triggers, delays, reverbs, etc., most of the time. |
